                                  THE COMPANY

     Titan is an independent energy company engaged in the exploitation,
development, exploration and acquisition of oil and gas properties located in
the Permian Basin of West Texas and southeastern New Mexico.  In late 1997, the
Company expanded its core operating areas into the Gulf Coast Region through
acquisitions onshore in South Texas and Louisiana and offshore in the Gulf of
Mexico.  Since its inception in March 1995, the Company has increased its
reserves, production and cash flow through (i) the development and exploration
of its properties and (ii) the acquisition of producing properties that provide
exploitation, development and exploration potential.  As of December 31, 1997,
the Company had proved reserves of 527 Bcfe, with a PV-10 of $435.1 million, and
operated 821 productive gross (724 net) wells.  Natural gas constituted
approximately 66% of the Company's reserves, and approximately 68% of the
Company's reserves were classified as proved developed.

     From its inception through December 31, 1997, the Company has made five
significant acquisitions for an aggregate purchase price of approximately $357.1
million, approximately $277.2 million of which is attributable to proved
reserves and $53.7 million of which is attributable to mid-stream gas gathering
and processing assets acquired in connection with the acquisition of Offshore
Energy Development Corporation.  These acquisitions have added approximately 326
Bcfe of reserves at an average cost of $0.85 per Mcfe.  Subsequently, the
Company has spent approximately $32.3 million on the exploitation, development
and exploration of these acquired properties, adding 175 Bcfe of proved reserves
at an average finding cost of $0.18 per Mcfe.  As a result, the Company's
finding cost from proved properties on these five acquisitions through December
31, 1997 was $0.62 per Mcfe.

                                  RISK FACTORS

     In addition to the other information contained or incorporated by reference
in this Prospectus, the following should be considered carefully by prospective
purchasers in evaluating an investment in the shares of Common Stock offered by
this Prospectus.

VOLATILITY OF OIL AND GAS PRICES; MARKETABILITY OF PRODUCTION
 
     The Company's revenues, operating results and future rate of growth are
highly dependent upon the prices received for the Company's oil and gas.
Historically, the markets for oil and gas have been volatile and may continue to
be volatile in the future.  Various factors beyond the control of the Company
will affect prices of oil and gas, including but not limited to the worldwide
and domestic supplies of oil and gas, the ability of the members of the
Organization of  Petroleum Exporting Countries ("OPEC") to agree to and maintain
oil price and production controls, political instability or armed conflict in
oil-producing regions, the price and level of foreign imports, the level of
consumer demand, the price and availability of alternative fuels, the
availability of pipeline capacity, weather conditions, domestic and foreign
governmental regulations and taxes and the overall economic environment.  The
Company is unable to predict the long-term effects of these and other conditions
on the prices of oil.  Lower oil and gas prices may reduce the amount of oil and
gas the Company can produce economically which may adversely affect the
Company's revenues and operating income and may require a reduction in the
carrying value of the Company's oil and gas properties.  Substantially all of
the Company's sales of oil and gas are made in the spot market or pursuant to
contracts based on spot market prices and not pursuant to long-term fixed price
contracts.  With the objective of reducing price risk, the Company enters into
hedging transactions with respect to a portion of its expected future
production.  There can be no assurance, however, that such hedging transactions
will reduce risk or mitigate the effect of any substantial or extended decline
in oil or natural gas prices.

     The marketability of the Company's production depends in part upon the
availability, proximity and capacity  of natural gas gathering systems,
pipelines and processing facilities.  Most of the Company's natural gas is
delivered through gas gathering systems and gas pipelines that are not owned by
the Company.  Federal and state regulation of oil and gas production and
transportation, tax and energy policies, changes in supply and demand and
general economic conditions all could adversely affect the Company's ability to
produce and market its oil and gas.  Any dramatic change in market factors could
have a material adverse effect on the Company's business, financial condition
and results of operations.

UNCERTAINTY OF RESERVE INFORMATION AND FUTURE NET REVENUE ESTIMATES

      There are numerous uncertainties inherent in estimating quantities of
proved reserves and their values, including many factors beyond the Company's
control.  The reserve information set forth in the Company's filings with the
Commission represents estimates only.  Although the Company believes such
estimates to be reasonable, reserve estimates are imprecise and should be
expected to change as additional information becomes available.

                                       4
<PAGE>
 
     Estimates of oil and gas reserves, by necessity, are projections based on
the evaluation of available geological, geophysical, economic and engineering
data, and there are uncertainties inherent in the interpretation of such data as
well as the projection of future rates of production and the timing of
development expenditures.  Reserve engineering is a subjective process of
estimating underground accumulations of oil and gas that are difficult to
measure.  The accuracy of any reserve estimate is a function of the quality of
available data, engineering and geological interpretation and judgment.
Estimates of economically recoverable oil and gas reserves and of future net
cash flows necessarily depend upon a number of variable factors and assumptions,
such as historical production from the area compared with production from other
producing areas, the assumed effects of regulations by governmental agencies and
assumptions concerning future oil and gas prices, future operating costs,
severance and excise taxes, development costs and workover and remedial costs,
all of which may in fact vary considerably from actual results. For these
reasons, estimates of the economically recoverable quantities of oil and gas
attributable to any particular group of properties, classifications of such
reserves based on risk of recovery and estimates of the future net cash flows
expected therefrom may vary substantially from those estimated in the Company's
filings with the Commission.  Moreover, there can be no assurance that the
Company's reserves will ultimately be produced or that the Company's proved
undeveloped reserves, the recovery of which requires significant capital
expenditures and successful drilling operations, will be developed within the
periods anticipated. Any significant variance in the assumptions could
materially affect the estimated quantity and value of the Company's reserves.
Actual production, revenues and expenditures with respect to the Company's
reserves will likely vary from estimates, and such variances may be material.

     Approximately 32% of the Company's total proved reserves at December 31,
1997 were undeveloped, which are by their nature less certain.  Recovery of such
reserves will require significant capital expenditures and successful drilling
operations.  The reserve data set forth in the Company's estimates assumes that
substantial capital expenditures by the Company will be required to develop such
reserves.  Although cost and reserve estimates attributable to the Company's oil
and gas reserves have been prepared in accordance with industry standards, no
assurance can be given that the estimated costs are accurate, that development
will occur as scheduled or that the results will be as estimated.

     In addition, the PV-10 referred to in this report should not be construed
as the current market value of the estimated oil and gas reserves attributable
to the Company's properties.  In accordance with applicable requirements, the
estimated discounted future net cash flows from proved reserves are generally
based on prices and costs as of the date of the estimate, whereas actual future
prices and costs may be materially higher or lower.  Actual future net cash
flows also will be affected by factors such as the amount and timing of actual
production, supply and demand for oil and gas, curtailments or increases in
consumption by gas purchasers and changes in governmental regulations or
taxation.  The timing of actual future net cash flows from proved reserves, and
thus their actual present value, will be affected by the timing of both the
production and the incurrence of expenses in connection with development and
production of oil and gas properties.  In addition, the 10% discount factor,
which is required by the Commission to be used to calculate discounted future
net cash flows for reporting purposes, is not necessarily the most appropriate
discount factor based on interest rates in effect from time to time and risks
associated with the Company or the oil and gas industry in general.

RESERVE REPLACEMENT RISK

     The Company's future success depends upon its ability to find, develop or
acquire additional oil and gas reserves that are economically recoverable.  The
proved reserves of the Company will generally decline as reserves are depleted,
except to the extent that the Company conducts successful exploration or
development activities or acquires properties containing proved reserves, or
both.  In order to increase reserves and production, the Company must continue
its development and exploration drilling and recompletion programs or undertake
other replacement activities.

     Exploratory drilling and, to a lesser extent, development drilling involve
a high degree of risk that no commercial production will be obtained or that the
production will be insufficient to recover drilling and completion costs.  The
costs of drilling, completing and operating wells are uncertain.  The Company's
drilling operations may be curtailed, delayed or canceled as a result of
numerous factors, including title problems, weather conditions, compliance with
governmental requirements and shortages or delays in the delivery of equipment.
Furthermore, completion of a well does not assure a profit on the investment or
a recovery of drilling, completion and operations costs.

     There are certain risks associated with secondary recovery operations,
especially the use of waterflooding techniques. Part of the Company's inventory
of development prospects consists of waterflood projects.  Waterflooding
involves significant capital expenditures and uncertainty as to the total amount
of secondary reserves that can be recovered.  In waterflood operations, there is
generally a delay between the initiation of water injection into a formation
containing hydrocarbons and any increase in production that may result.  The
operating cost per unit of production of waterflood projects is generally higher
during the initial phases of such 

                                       5
<PAGE>
 
projects due to the purchase of injection water and related costs, as well as
during the later stages of the life of the project as production declines. The
degree of success, if any, of any secondary recovery program depends on a large
number of factors, including the porosity of the formation, the technique used
and the location of injector wells.

     The Company's current strategy includes increasing its reserve base through
acquisitions of producing properties, continued exploitation of its existing
properties and exploration of new and existing properties.  There can be no
assurance, however, that the Company's planned development and exploration
projects and acquisition activities will result in significant additional
reserves or that the Company will have continuing success drilling productive
wells at low finding and development costs.  Furthermore, while the Company's
revenues may increase if prevailing oil and gas prices increase significantly,
the Company's finding costs for additional reserves could also increase.

ACQUISITION RISKS

     The Company expects to continue to evaluate and pursue acquisition
opportunities available on terms management considers favorable to the Company.
The successful acquisition of producing properties involves an assessment of
recoverable reserves, future oil and gas prices, operating costs, potential
environmental and other liabilities and other factors beyond the Company's
control.  This assessment is necessarily inexact and its accuracy is inherently
uncertain.  In connection with such an assessment of the subject properties, the
Company performs a review it believes to be generally consistent with industry
practices. This review, however, will not reveal all existing or potential
problems, nor will it permit a buyer to become sufficiently familiar with the
properties to assess fully their deficiencies and capabilities.  Inspections may
not be performed on every well, and structural and environmental problems are
not necessarily observable even when an inspection is undertaken.  The Company
generally assumes preclosing liabilities, including environmental liabilities,
and generally acquires interests in the properties on an "as is" basis.  With
respect to its acquisitions to date, the Company has no material commitments for
capital expenditures to comply with existing environmental requirements.  In
addition, volatile oil and gas prices make it difficult to estimate the value of
producing properties for acquisition and often cause disruption in the market
for oil and gas producing properties, as buyers and sellers have difficulty
agreeing on such value.  Price volatility also makes it difficult to budget for
and project the return on acquisitions and development and exploration projects.
There can be no assurance that the Company's acquisitions will be successful.
Any unsuccessful acquisition could have a material adverse effect on the
Company.

LIMITED OPERATING HISTORY; RAPID GROWTH

     The Company, which began operations in March 1995, has a brief operating
history, including three years of net losses, and has experienced rapid growth.
As a result, the Company's historical results are not readily comparable to and
may not be indicative of future results.  There can be no assurance that the
Company will continue to experience growth in, or maintain its current level of,
revenues, oil and gas reserves or production.  In addition, the Company's
predecessor was classified as a partnership for federal income tax purposes.
Therefore, no income taxes were paid by the Company prior to the conversion to a
corporation.  Future tax amounts, if any, will be dependent upon several
factors, including, but not limited to, the Company's results of operations.

     The Company's rapid growth has placed significant demands on its
administrative, operational and financial resources. Any future growth of the
Company's oil and gas reserves, production and operations would place
significant further demands on the Company's financial, operational and
administrative resources.  The Company's future performance and profitability
will depend in part on its ability to successfully integrate the administrative
and financial functions of acquired properties and companies into the Company's
operations, to hire additional personnel and to implement necessary enhancements
to its management systems to respond to changes in its business.  There can be
no assurance that the Company will be successful in these efforts.  The
inability of the Company to integrate acquired properties and companies, to hire
additional personnel or to enhance its management systems could have a material
adverse effect on the Company's results of operations.

SUBSTANTIAL CAPITAL REQUIREMENTS

     The Company makes, and will continue to make, substantial capital
expenditures for the exploration, development, acquisition and production of its
oil and gas reserves.  The Company intends to finance such capital expenditures
primarily with funds provided by operations, the incurrence of debt, the
issuance of equity and the sale of non-core assets.  The Company's direct
capital expenditures for oil and gas producing activities were $2.0 million for
the nine months ended December 31, 1995 and $12.6 million and $47.8 million for
the years ended December 31, 1996 and 1997, respectively.  If revenues decrease
as a result of lower oil or gas prices or otherwise, the Company may have
limited ability to expend the capital necessary to replace its reserves or to
maintain production at current levels, resulting in a decrease in production
over time.  If the Company's cash flow from operations 

                                       6
<PAGE>
 
and availability under the its credit agreement are not sufficient to satisfy
its capital expenditure requirements, there can be no assurance that additional
debt or equity financing will be available to meet these requirements.

EFFECTS OF LEVERAGE

     The Company has certain debt obligations that may have several important
effects on its operations, including (i) a substantial portion of the Company's
cash flow from operations will be dedicated to the payment of interest on its
indebtedness and will not be available for other purposes; (ii) the covenants
contained in the Company's credit facility limit its ability to borrow
additional funds or to dispose of assets and may affect the Company's
flexibility in planning for, and reacting to, changes in business conditions and
(iii) the Company's ability to obtain additional financing in the future for
working capital, capital expenditures, acquisitions, general corporate purposes
or other purposes may be impaired.  Moreover, future acquisition or development
activities may require the Company to alter its capitalization significantly.
These changes in capitalization may significantly alter the leverage of the
Company.  The Company's ability to meet its debt service obligations and to
reduce its total indebtedness will be dependent upon the Company's future
performance, which will be subject to general economic conditions and to
financial, business and other factors affecting the operations of the Company,
many of which are beyond its control.  There can be no assurance that the
Company's future performance will not be adversely affected by such economic
conditions and financial, business and other factors.

DRILLING AND OPERATING RISKS; UNINSURED RISKS

     Drilling activities are subject to many risks, including well blow outs,
cratering, uncontrollable flows of oil, natural gas or well fluids, fires,
formations with abnormal pressures, pollution, releases of toxic gases and other
environmental hazards and risks, any of which could result in substantial losses
to the Company.  The Company's offshore operations are also subject to the
additional hazards of marine operations such as severe weather, capsizing and
collision.  In addition, the Company incurs the risk that no commercially
productive reservoirs will be encountered through its drilling operations.
There can be no assurance that new wells drilled by the Company will be
productive or that the Company will recover all or any portion of its investment
in wells drilled.  Drilling for oil and gas may involve unprofitable efforts,
not only from dry wells, but from wells that are productive but do not produce
net reserves to return a profit after drilling, operating and other costs.  The
cost of drilling, completing and operating wells is often uncertain.  The
Company's drilling operations may be curtailed, delayed or canceled as a result
of numerous factors, many of which are beyond its control, including economic
conditions, mechanical problems, title problems, weather conditions, compliance
with governmental requirements and shortages and delays in the delivery of
equipment and services.  In accordance with industry practices, the Company
maintains insurance against some, but not all, of these risks.  There can be no
assurance that any insurance of the Company will be adequate to cover losses or
liabilities.

RISK OF HEDGING ACTIVITIES

     The Company's use of energy swap arrangements and financial futures to
reduce its sensitivity to oil and gas price volatility is subject to a number of
risks.  If the Company's reserves are not produced at the rates estimated by the
Company due to inaccuracies in the reserve estimation process, operational
difficulties or regulatory limitations, the Company would be required to satisfy
obligations it may have under fixed price sales and hedging contracts on
potentially unfavorable terms without the ability to hedge that risk through
sales of comparable quantities of its own production.  Further, the terms under
which the Company enters into fixed price sales and hedging contracts are based
on assumptions and estimates of numerous factors such as cost of production and
pipeline and other transportation costs to delivery points.  Substantial
variations between the assumptions and estimates used by the Company and actual
results experienced could materially adversely affect the Company's anticipated
profit margins and its ability to manage the risk associated with fluctuations
in oil and gas prices.  Additionally, fixed price sales and hedging contracts
limit the benefits the Company will realize if actual prices rise above the
contract prices.  In addition, fixed price sales and hedging contracts are
subject to the risk that the counter-party may prove unable or unwilling to
perform its obligations under such contracts.  Any significant nonperformance
could have a material adverse financial effect on the Company.  As of June 30,
1998, 7,820 and 6,544 MMcfe of the Company's 1998 and 1999 production,
respectively, were subject to hedging contracts.

GAS GATHERING, PROCESSING AND MARKETING

     The Company's gas gathering, processing and marketing operations depend in
large part on the ability of the Company to contract with third party producers
to produce their gas, to obtain sufficient volumes of committed natural gas
reserves, to maintain throughput in the Company's processing plant at optimal
levels, to replace production from declining wells, to assess and respond to
changing market conditions in negotiating gas purchase and sale agreements and
to obtain satisfactory margins between the purchase price of its natural gas
supply and the sales price for such residual gas volumes and the natural gas
liquids processed. 

                                       7
<PAGE>
 
In addition, the Company's operations are subject to changes in regulations
relating to gathering and marketing of oil and gas. The inability of the Company
to attract new sources of third party natural gas or to promptly respond to
changing market conditions or regulations in connection with its gathering,
processing and marketing operations could materially adversely affect the
Company's business, financial condition and results of operations.

COMPLIANCE WITH GOVERNMENT REGULATIONS

     The Company's business is subject to federal, state and local laws and
regulations relating to the exploration for, and the development, production and
transportation of, oil and gas, as well as safety matters that change from time
to time in response to economic or political conditions.  Although the Company
believes it is in substantial compliance with all applicable laws and
regulations, the requirements imposed by such laws and regulations are
frequently changed and subject to interpretation, and the Company is unable to
predict the ultimate cost of compliance with these requirements or their effect
on its operations.  Significant expenditures may be required to comply with
governmental laws and regulations and may have a material adverse effect on the
Company's business,  financial condition and results of operations.

COMPLIANCE WITH ENVIRONMENTAL REGULATIONS

     The Company's operations are subject to complex and constantly changing
environmental laws and regulations adopted by federal, state and local
governmental authorities.  The implementation of new, or the modification of
existing, laws or regulations could have a material adverse affect on the
Company's business, financial condition and results of operations.  The
discharge of oil, gas or other pollutants into the air, soil or water may give
rise to significant liabilities on the part of the Company to the government and
third parties and may require the Company to incur substantial costs of
remediation.  Moreover, the Company has agreed to indemnify sellers of producing
properties purchased in each of its substantial acquisitions against
environmental claims associated with such properties.  No assurance can be given
that existing environmental laws or regulations, as currently interpreted or
reinterpreted in the future, or future laws or regulations will not materially
adversely affect the results of operations or financial condition of the Company
or that material indemnity claims will not arise against the Company with
respect to properties acquired by it.

COMPETITION

     The Company operates in the highly competitive areas of oil and gas
exploration, development, acquisition and production with other companies, many
of which have substantially larger financial resources, staffs and facilities.
In seeking to acquire desirable producing properties or new leases for future
exploration and in marketing its oil and gas production, the Company faces
intense competition from both major and independent oil and gas companies.  Many
of these competitors have financial and other resources substantially in excess
of those available to the Company.  This highly competitive environment could
have a material adverse affect on the Company.

DEPENDANCE ON KEY PERSONNEL

     The Company's success has been and will continue to be highly dependent on
Jack Hightower, its Chairman of the Board and Chief Executive Officer, and a
limited number of other senior management personnel.  Loss of the services of
Mr. Hightower or any of those other individuals could have a material adverse
effect on the Company's operations.  The Company maintains a $3.0 million key
man life insurance policy on the life of Mr. Hightower, but no other senior
management personnel.  In addition, as a result of the Company's acquisitions,
the Company has significantly increased its number of employees and employed 110
employees at June 30, 1998.  As the Company increases its workforce, it will
face competition for such personnel from other companies.  There can be no
assurance that the Company will be successful in hiring or retaining key
personnel.  The Company's failure to hire additional personnel or retain its key
personnel could have a material adverse effect on the Company's business,
financial condition and results of operations.

CONTROL BY EXISTING STOCKHOLDERS

     Directors, executive officers and principal stockholders of the Company,
and certain of their affiliates, beneficially own approximately 48.7% of the
Company's outstanding Common Stock on a fully-diluted basis (45.4% assuming the
sale of the Shares).  Accordingly, these stockholders, as a group, are able to
control the outcome of stockholder votes, including votes concerning the
election of directors, the adoption or amendment of provisions in the Company's
Amended Certificate of Incorporation or Bylaws and the approval of mergers and
other significant corporate transactions.  The existence of these levels of
ownership concentrated 

                                       8
<PAGE>
 
in a few persons makes it unlikely that any other holder of Common Stock will be
able to affect the management or direction of the Company. These factors may
also have the effect of delaying or preventing a change in the management or
voting control of the Company.

ANTI-TAKEOVER PROVISIONS

      Delaware law includes a number of provisions that may have the effect of
delaying or deterring a change in the control of management of the Company and
encouraging persons considering unsolicited tender offers or other unilateral
takeover proposals to negotiate with the Company's Board of Directors rather
than pursue non-negotiated takeover attempts.  These provisions may make it more
difficult for shareholders of the Company to benefit from certain transactions
which are opposed by the incumbent Board of Directors.

YEAR 2000 COMPLIANCE

     Many currently installed computer systems and software products are coded
to accept only two digit entries in the data code field.  These data code fields
will need to accept four digit entries to distinguish the 21st century dates
from 20th century dates. As a result, computer systems and software used by many
companies may need to be upgraded to comply with such "Year 2000" requirements.
Although the Company believes that its software products are Year 2000
compliant, there can be no assurance that the Company's software products
contain all necessary software routines and programs necessary for the accurate
calculation, display, storage and manipulation of data involving dates.
Moreover, the Company cannot determine what effect, if any, the Year 2000
requirements will have on its vendors, customers, other businesses with which
its conducts business and the numerous local, state, federal, and other U.S. and
foreign governmental entities by which it is regulated, governed or taxed.  No
assurance can be given that the computer systems and software of such entities
will be Year 2000 compliant or that compliance costs or the impact of the
Company's failure to achieve substantial Year 2000 compliance will not have a
material adverse effect on the Company's business, financial position and
results of operations.

                           FORWARD-LOOKING STATEMENTS

     Certain statements contained in or incorporated by reference into this
Prospectus, including, but not limited to, those regarding the Company's
financial position, business strategy and other plans and objectives for future
operations and any other statements which are not historical facts constitute
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995.  Such forward-looking statements involve known
and unknown risks, uncertainties and other important factors that could cause
the actual results, performance or achievements of the Company, or industry
results, to differ materially from any future results, performance or
achievements expressed or implied by such forward-looking statements. Although
the Company believes that the expectations reflected in these forward-looking
statements are reasonable, there can be no assurance that the actual results or
developments anticipated by the Company will be realized or, even if
substantially realized, that they will have the expected effects on its business
or operations.  Among the factors that could cause actual results to differ
materially from the Company's expectations are inherent uncertainties in
interpreting engineering and reserve data, operating hazards, delays or
cancellations of drilling operations for a variety of reasons, competition,
fluctuations and volatility in oil and gas prices, the ability of the Company to
successfully integrate the business and operations of acquired companies,
compliance with government and environmental regulations, increases in the
Company's cost of borrowing or inability or unavailability of capital resources
to fund capital expenditures, dependence on key personnel, changes in general
economic conditions and/or in the markets in which the Company competes or may,
from time to time, compete and other factors including but not limited to those
set forth in "Risk Factors" or in "The Company."  All subsequent oral and
written forward-looking statements attributable to the Company or persons acting
on its behalf are expressly qualified in their entirety by these factors.  The
Company assumes no obligation to update any of these statements.

1, 1997 with respect to the unaudited pro forma combined statement of
operations.  Each acquisition is recorded using the purchase method of
accounting, any future adjustments to the initial allocation of the purchase
price are not anticipated to be material to the unaudited pro forma combined
statement of operations.

     Following is a description of the individual columns included in the
unaudited pro forma combined statement of operations:

     TITAN.  Represents the consolidated statement of operations of Titan
Exploration, Inc. (the "Company") for the year ended December 31, 1997.

NOTE 3. INCOME TAXES

     The Company accounts for income taxes pursuant to the provisions of
Statement of Financial Accounting Standards No. 109 "Accounting for Income
Taxes."

NOTE 4. SUPPLEMENTAL OIL AND GAS RESERVE INFORMATION (UNAUDITED)

     The following unaudited pro forma combined supplemental information
regarding the oil and gas activities of the Company is presented pursuant to the
disclosure requirements promulgated by the Securities and Exchange Commission
and Statement of Financial Accounting Standards No. 69, "Disclosures About Oil
and Gas Producing Activities".  The pro forma combined reserve information is
presented as if the OEDC Acquisition, Pioneer Acquisition and the Carrollton
Acquisition had occurred on January 1, 1997.

     Management emphasizes that reserve estimates are inherently imprecise and
subject to revision and that estimates of new discoveries are more imprecise
than those of producing oil and gas properties.  Accordingly, the estimates are
expected to change as future information becomes available; such changes could
be significant.

Quantities of oil and gas reserves

     Set forth below is a pro forma summary of the changes in the net quantities
of oil and natural gas reserves for the year ended December 31, 1997.

Standardized measure of discounted future net cash flows

     The pro forma combined standardized measure of discounted future net cash
flows is computed by applying year-end prices of oil and gas (with consideration
of price changes only to the extent provided by contractual arrangements) to the
estimated future production of oil and gas reserves less estimated future
expenditures (based on year-end costs) to be incurred in developing timing of
the future cash flows.  Future income taxes are calculated by comparing
discounted future cash flows to the tax basis of oil and gas properties, plus
available carryforwards and credits, and applying the current tax rate to the
difference.

                                                             December 31,

                              PLAN OF DISTRIBUTION

     The Shares may be sold from time to time by the Selling Stockholders,
subject to certain restrictions, including the contractual restriction limiting
the Selling Stockholders to the sale of one-half of their Shares prior to
December 12, 1998 (see "Selling Stockholders"), after June 10, 1998.   All sales
may be made by the Selling Stockholders on the Nasdaq, in privately negotiated
transactions or otherwise at prices and at terms related to the then current
market price, or in negotiated transactions. The Shares may be sold by any one
or more of the following methods:

     (a) a block trade in which the broker or dealer so engaged will attempt to
sell the Shares as agent, but may position and resell a portion of a block as
principal to facilitate the transaction;

     (b) underwritten public offering;

     (c) purchases by a broker or dealer as principal, and resale by such broker
or dealer, for its account pursuant to this Prospectus;

     (d) ordinary brokerage transactions and transactions in which the broker
solicits purchasers; and

     (e) privately negotiated transactions.

     The Selling Stockholders may effect such transactions by selling the Shares
through or to brokers or dealers, and such brokers or dealers will receive
compensation in the form of discounts or commissions from the Selling
Stockholders, and may receive commissions from the purchasers of the Shares for
whom they may act as agent (which discounts or commissions from the Selling
Stockholders or such purchasers might exceed those customary in the types of
transactions involved).

     Any Shares covered by this Prospectus which qualify for sale pursuant to
Rule 144 or Rule 145 under the Securities Act may be sold under that Rule rather
than pursuant to this Prospectus.

     There can be no assurance that the Selling Stockholders will sell any or
all of the Shares offered by them hereunder.

     The Company will pay all fees and expenses incident to the preparation and
filing of the Registration Statement and this Prospectus, including legal and
accounting fees and expenses and any printing expenses other than any
underwriting discounts, any selling commissions payable in respect of sales of
the Shares; all of which will be paid by the Selling Stockholders.  The Company
will receive no part of the proceeds from sales of the Shares.  The Company
intends to keep the Registration Statement effective until the earlier of such
time as the number of Shares held by the Selling Stockholders represents less
than 10% of the initial number of Shares and December 12, 1999.

     The Selling Stockholders and any broker-dealer acting in connection with
the sale of the Shares offered hereby may be deemed to be "underwriters" within
the meaning of the Securities Act, in which event any discounts, concessions or
commissions received by them, which are not expected to exceed those customary
in the types of transactions involved, or any profit on resales of the Shares by
them, may be deemed to be underwriting commissions or discounts under the
Securities Act.

                                 LEGAL MATTERS

     The legality of the Shares offered hereby will be passed upon for the
Company by Thompson & Knight, P.C., Dallas, Texas.

and in most instances are rounded to the nearest major multiple.  BOEs are
determined using the ratio of six Mcf of natural gas to one Bbl of oil.

     "1995 Acquisition" means the acquisition of a concentrated group of Permian
Basin producing oil and gas properties from a large independent company for
approximately $40.6 million in December 1995.

     "1996 Acquisition" means the acquisition of Permian Basin producing
properties from a major integrated company for approximately $135.7 million in
October 1996.

     "Bbl" means a barrel of 42 U.S. gallons of oil.

     "Bcf" means billion cubic feet of natural gas.

     "Bcfe" means billion cubic feet equivalent, determined using the ratio of
six Mcf of natural gas to one Bbl of crude oil, condensate or natural gas
liquids.

     "BOE" means barrels of oil equivalent.

     "Completion" means the installation of permanent equipment for the
production of oil or gas.

     "Development well" means a well drilled within the proved area of an oil or
gas reservoir to the depth of a stratigraphic horizon known to be productive.

     "EBITDAX" means net income (loss) plus income taxes, exploration and
abandonment expense, interest expense, depletion, depreciation and amortization,
impairment of long-lived assets and amortization of stock option awards.

     "Exploratory well" means a well drilled to find and produce oil or gas in
an unproved area, to find a new reservoir in a field previously found to be
productive of oil or gas in another reservoir, or to extend a known reservoir.

     "Gross," when used with respect to acres or wells, refers to the total
acres or wells in which the Company has a working interest.

     "Horizontal drilling" means a drilling technique that permits the operator
to contact and intersect a larger portion of the producing horizon than
conventional vertical drilling techniques and can result in both increased
production rates and greater ultimate recoveries of hydrocarbons.

     "MBbls" means thousands of barrels of oil.

     "Mcf" means thousand cubic feet of natural gas.

     "Mcfe" means 1,000 cubic feet equivalent, determined using the ratio of six
Mcf of natural gas to one Bbl of crude oil, condensate or natural gas liquids.

     "MMBOE" means millions of barrels of oil equivalent on a 6:1 basis.

     "MMcf" means million cubic feet of natural gas.

     "MMcfe" means million cubic feet equivalent, determined using the ratio of
six Mcf of natural gas to one Bbl of crude oil, condensate or natural gas
liquids.

                                       18
<PAGE>
 
     "Net," when used with respect to acres or wells, refers to gross acres of
wells multiplied, in each case, by the percentage working interest owned by the
Company.

     "Net production" means production that is owned by the Company less
royalties and production due others.

     "Oil" means crude oil or condensate.

     "Operator" means the individual or company responsible for the exploration,
development, and production of an oil or gas well or lease.

     "Present Value of Future Revenues" or "PV-10" means the pretax present
value of estimated future revenues to be generated from the production of proved
reserves calculated in accordance with SEC guidelines, net of estimated
production and future development costs, using prices and costs as of the date
of estimation without future escalation, without giving effect to non-property
related expenses such as general and administrative expenses, debt service and
depreciation, depletion and amortization, and discounted using an annual
discount rate of 10%.

     "Proved developed reserves" means reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery will be included as "proved developed
reserves" only after testing by a pilot project or after the operation of an
installed program has confirmed through production response that increased
recovery will be achieved.

     "Proved reserves" means the estimated quantities of crude oil, natural gas,
and natural gas liquids which geological and engineering data demonstrate with
reasonable certainty to be recoverable in future years from known reservoirs
under existing economic and operating conditions, i.e., prices and costs as of
the date the estimate is made.  Prices include consideration of changes in
existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.

          i.  Reservoirs are considered proved if economic producibility is
     supported by either actual production or conclusive formation test.  The
     area of a reservoir considered proved includes (A) that portion delineated
     by drilling and defined by gas-oil and/or oil-water contacts, if any; and
     (B) the immediately adjoining portions not yet drilled, but which can be
     reasonably judged as economically productive on the basis of available
     geological and engineering data.  In the absence of information on fluid
     contacts, the lowest known structural occurrence of hydrocarbons controls
     the lower proved limit of the reservoir.

          ii.  Reserves which can be produced economically through application
     of improved recovery techniques (such as fluid injection) are included in
     the "proved" classification when successful testing by a pilot project, or
     the operation of an installed program in the reservoir, provides support
     for the engineering analysis on which the project or program was based.

          iii.  Estimates of proved reserves do not include the following:  (A)
     oil that may become available from known reservoirs but is classified
     separately as "indicated additional reserves"; (B) crude oil, natural gas,
     and natural gas liquids, the recovery of which is subject to reasonable
     doubt because of uncertainty as to geology, reservoir characteristics, or
     economic factors; (C) crude oil, natural gas, and natural gas liquids that
     may occur in undrilled prospects; and (D) crude oil, natural gas, and
     natural gas liquids that may be recovered from oil shales, coal, gilsonite
     and other such sources.

     "Proved undeveloped reserves" means reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion.  Reserves on
undrilled acreage shall be limited to those drilling units offsetting productive
units that are reasonably certain of production when drilled.  Proved reserves
for other undrilled units can be claimed only where it can be demonstrated with
certainty that there is continuity of production from the existing productive
formation.  Under no circumstances should estimates for proved undeveloped
reserves be attributable to any acreage for which an application of fluid
injection or other improved recovery technique is contemplated, unless such
techniques have been proved effective by actual tests in the area and in the
same reservoir.

     "Recompletion" means the completion for production of an existing well bore
in another formation from that in which the well has been previously completed.

                                       19
<PAGE>
 
     "Reserve Life Index" means how long it will take to produce a quantity of
proved reserves, calculated by dividing year-end proved reserves by annual
production for the most recent year.

     "Reserves" means proved reserves.

     "Royalty" means an interest in an oil and gas lease that gives the owner of
the interest the right to receive a portion of the production from the leased
acreage (or of the proceeds of the sale thereof), but generally does not require
the owner to pay any portion of the costs of drilling or operating the wells on
the leased acreage.  Royalties may be either landowner's royalties, which are
reserved by the owner of the leased acreage at the time the lease is granted, or
overriding royalties, which are usually reserved by an owner of the leasehold in
connection with a transfer to a subsequent owner.

     "Secondary recovery" means

     "3-D seismic" means seismic data that are acquired and processed to yield a
three-dimensional picture of the subsurface.

     "Tcf" means trillion cubic feet of natural gas.

     "Tertiary recovery" means enhanced recovery methods for the production of
oil or gas.  Enhanced recovery of crude oil requires a means for displacing oil
from the reservoir rock, modifying the properties of the fluids in the reservoir
and/or the reservoir rock to cause movement of oil in an efficient manner, and
providing the energy and drive mechanism to force its flow to a production well.
The Company injects chemicals or energy as required for displacement and for the
control of flow rate and flow pattern in the reservoir, and a fluid drive is
provided to force the oil toward a production well.

     "Working interest" means an interest in an oil and gas lease that gives the
owner of the interest the right to drill for and produce oil and gas on the
leased acreage and requires the owner to pay a share of the costs of drilling
and production operations. The share of production to which a working interest
owner is entitled will always be smaller than the share of costs that the
working interest owner is required to bear, with the balance of the production
accruing to the owners of royalties.  For example, the owner of a 100% working
interest in a lease burdened only by a landowner's royalty of 12.5% would be
required to pay 100% of the costs of a well but would be entitled to retain
87.5% of the production.

     "Workover" means operations on a producing well to restore or increase
production.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 102(b)(7) of the Delaware General Corporation Law ("DGCL") enables
a corporation to include in its certificate of incorporation a provision
eliminating or limiting the personal liability of members of its board of
directors to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director.  Such a provision may not eliminate or limit
the liability of a director (1) for any breach of a director's duty of loyalty
to the corporation or its stockholders, (2) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of a law,
(3) for paying an unlawful dividend or approving an illegal stock repurchase (as
provided in Section 174 of the DGCL), or (4) for any transaction from which the
director derived an improper personal benefit.

     Under Section 145 of the DGCL, a corporation has the power to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding (other than an
action by or in the right of the corporation) by reason of the fact that the
person is or was a director, officer, employee or agent of any corporation,
partnership, joint venture, trust or other enterprise, against any and all
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement and reasonably incurred in connection with such action, suit or
proceeding.  The power to indemnify applies only if the person acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and with respect to any criminal action or
proceeding, had no reasonable cause to believe the person's conduct was
unlawful.

     In the case of an action by or in the right of the corporation, no
indemnification may be made with respect to any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the court of chancery or the court in which
such action or suit was brought shall determine that despite the adjudication of
liability such person is fairly and reasonably entitled to indemnity for such
expenses which the court shall deem proper.  Section 145 of the DGCL further
provides that to the extent a director or officer of a corporation has been
successful in the defense of any action, suit or proceeding referred to above or
in the defense of any claim, issue or matter therein, he shall be indemnified
against expenses (including attorney's fees) actually and reasonably incurred by
him in connection therewith.

     A corporation also has the power to purchase and maintain insurance on
behalf of any person covering any liability incurred by such person in his
capacity as a director, officer, employee or agent of the corporation, or
arising out of his status as such, whether or not the corporation would have the
power to indemnify him against such liability.

     The Registrant's Certificate of Incorporation and Bylaws provide that no
director of the Registrant will be personally liable to the Registrant or any of
its stockholders for monetary damages arising from the director's breach of
fiduciary duty as a director. However, this does not apply with respect to any
action in which the director would be liable under Section 174 of Title 8 of the
DGCL nor does it apply with respect to any liability in which the director (i)
breached his duty of loyalty to the Registrant; (ii) did not act in good faith
or, in failing to act, did not act in good faith; (iii) acted in a manner
involving intentional misconduct or a knowing violation of law or, in failing to
act, shall have acted in a manner involving intentional misconduct or a knowing
violation of law; or (iv) derived an improper personal benefit.

     The Certificate of Incorporation and Bylaws provide that the Registrant
will indemnify its officers and directors and former officers and directors
against any expenses, judgments or settlement payments sustained or paid by such
persons as a result of having acted as an officer or director of the Registrant,
or, at the request of the Registrant, as an officer, director, agent or employee
of another business entity. The Certificate of Incorporation and Bylaws further
provide that the Registrant may, by action of its Board 
<PAGE>
 
of Directors, provide indemnification to employees and agents of the Registrant,
individually or as a group, with the same scope and effect as the
indemnification of directors and officers.

 
ITEM 16.  EXHIBITS.

     The information required by this Item 16 is set forth in the Index to
Exhibits accompanying this Registration Statement.


ITEM 17.  UNDERTAKINGS.

     (a)  Rule 415 Offering.

     The undersigned Registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement:

               (i)    to include any prospectus required by Section 10(a)(3) of
          the Securities Act of 1933;

               (ii)   to reflect in the prospectus any facts or events arising
          after the effective date of the Registration Statement (or the most
          recent post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the Registration Statement.  Notwithstanding the foregoing, any
          increase or decrease in volume of securities offered (if the total
          dollar value of securities offered would not exceed that which was
          registered) and any deviation from the low or high end of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Commission pursuant to Rule 424(b) if, in
          the aggregate, the changes in volume and price represent no more than
          a 20% change in the maximum aggregate offering price set forth in the
          "Calculation of Registration Fee" table in the effective registration
          statement; and

               (iii)  to include any material information with respect to the
          plan of distribution not previously disclosed in the Registration
          Statement or any material change to such information in the
          Registration Statement;

     provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
     the information required to be included in a post-effective amendment by
     those paragraphs is contained in periodic reports filed by the Registrant
     pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of
     1934 that are incorporated by reference in the Registration Statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

     (b) Filings incorporating subsequent Exchange Act documents by reference.

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's Annual Report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (h) Request for acceleration of effective date.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described in Item 15 above, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as 
<PAGE>
 
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

Re:    TITAN EXPLORATION, INC.;
       FORM S-3 REGISTRATION STATEMENT

Gentlemen:

     We have acted as counsel for Titan Exploration, Inc. (the "Company"), in
connection with the preparation of the Company's Registration Statement on Form
S-3 (the "Registration Statement"), filed with the Securities and Exchange
Commission (the "Commission") under the Securities Act of 1933, as amended (the
"Securities Act"), covering the proposed sale of up to 1,749,445 shares (the
"Shares") of Common Stock, par value $.01 per share, of the Company by the
Selling Stockholders named therein (the "Selling Stockholders").  The Shares are
proposed to be sold by the Selling Stockholders in the manner set forth in the
Prospectus constituting Part I of the Registration Statement under the caption
"Plan of Distribution".

     In connection with the foregoing, we have examined the originals or copies,
certified or otherwise authenticated to our satisfaction, of such corporate
records of the Company, certificates of public officials and other instruments
and documents as we have deemed necessary to require as a basis for the opinion
hereinafter expressed.  As to questions of fact material to such opinion, we
have, where relevant facts are not independently established, relied upon
statements of officers of the Company.

     On the basis of the foregoing and in reliance thereon, we advise you that
in our opinion the Shares to be sold by the Selling Stockholders pursuant to the
Registration Statement have been duly and validly authorized by the Company and,
when sold by the Selling Stockholders as described in the Registration
Statement, will be legally issued, fully paid and nonassessable.

     We hereby consent to the filing of this opinion with the Commission as
Exhibit 5.1 of the Registration Statement and to the reference to us in the
Prospectus under the caption "Legal Matters".  In giving this consent, we do not
thereby admit that we come within the category of persons whose consent is
required under Section 7 of the Securities Act or the rules or regulations of
the Commission thereunder.

                              Respectfully submitted,

                              THOMPSON & KNIGHT, P.C.
                                A Professional Corporation
