                        REPORT OF INDEPENDENT ACCOUNTANTS

The Board of Directors and Stockholders
of Patterson Energy, Inc.:

We have reviewed the accompanying condensed consolidated balance sheet of
Patterson Energy, Inc. and its Subsidiaries as of March 31, 1998, and the
related condensed consolidated statements of operations and cash flows for the
three months ended March 31, 1998 and 1997 and the related condensed
consolidated statement of stockholders' equity for the three months ended March
31, 1998. These financial statements are the responsibility of the Company's
management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants. A review of interim financial
information consists principally of applying analytical review procedures to
financial data and making inquiries of persons responsible for financial and
accounting matters. It is substantially less in scope than an audit conducted in
accordance with generally accepted auditing standards, the objective of which is
the expression of an opinion regarding the financial statements taken as a
whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the accompanying condensed consolidated financial statements for them
to be in conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet as of December 31, 1997 and the
related consolidated statements of income and cash flows for the year then ended
(not presented herein); and in our report dated February 27, 1998, we expressed
an unqualified opinion on those consolidated financial statements. In our
opinion, the information set forth in the accompanying condensed consolidated
balance sheet as of December 31, 1997 is fairly stated, in all material
respects, in relation to the consolidated balance sheet from which it has been
derived.

                     PATTERSON ENERGY, INC. AND SUBSIDIARIES
         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.       BASIS OF CONSOLIDATION AND PRESENTATION

         The consolidated financial statements include the accounts of Patterson
Energy, Inc. ("Patterson") and its wholly-owned subsidiaries, Patterson Drilling
Company, Patterson Onshore Drilling Company, Lone Star Mud, Inc., Patterson
Petroleum, Inc., Patterson Petroleum Trading Company, Inc. and Patterson
Drilling Programs, Inc. (collectively referred to hereafter as the "Company").
All significant intercompany accounts and transactions have been eliminated.

         The interim condensed consolidated financial statements have been
prepared by management of the Company, without audit, pursuant to the rules and
regulations of the Securities and Exchange Commission. Certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been omitted
pursuant to such rules and regulations, although the Company believes the
disclosures included herein are adequate to make the information presented not
misleading. In the opinion of management, all adjustments (consisting of only
normal recurring accruals) considered necessary for presentation of the
information have been included. The unaudited condensed consolidated balance
sheet as of December 31, 1997, as presented herein, was derived from the audited
balance sheet, but does not include all disclosures required by generally
accepted accounting principles.

         The results of operations for the three months ended March 31, 1998,
are not necessarily indicative of the results to be expected for the full year.

         Certain reclassifications have been made to the 1997 consolidated
financial statements in order for them to conform with the 1998 presentation.

         The Company's earnings per share and weighted average number of common
shares outstanding for all periods presented and, as otherwise indicated herein,
reflect two-for-one splits of the Company's common stock effected in July 1997
and in January 1998.

2.       RECENT ACQUISITIONS

         On January 5, 1998, the Company acquired 100% of the outstanding stock
of Lone Star Mud, Inc. ("Lone Star"), a privately-owned, non-affiliated company
based in Midland, Texas. The purchase price of approximately $12.98 million
consisted of $1.430 million in cash, 571,328 million shares of the Company's
common stock valued at $17.41 per share, which was the market price on the
acquisition date, the assumption of $1.6 million of debt and approximately
$3,300 of other direct costs incurred related to the transaction. Pursuant to
certain terms of the Company's existing loan agreement with Norwest Bank Texas,
N.A. ("Norwest"), the outstanding balance of the above mentioned note payable
was paid in full. The fair market values of the assets acquired were estimated
and the purchase price, as of the date of the acquisition, was allocated as
follows (in thousands):

2.       RECENT ACQUISITIONS - CONTINUED

         On February 6, 1998, the Company completed the merger of Robertson
Onshore Drilling Company ("Robertson") a privately-owned, non-affiliated,
contract drilling company based in Dallas, Texas, with and into Patterson
Onshore Drilling Company, a wholly-owned subsidiary of Patterson Drilling
Company. The purchase price of approximately $42.245 million was funded using
cash on hand of approximately $3.695 million, proceeds of $36.75 million
provided by the Company's line of credit and the assumption of $1.8 million of
debt. The assets acquired consisted of 15 operable drilling rigs and a shop and
yard located in Liberty City, Texas. The purchase price, as of the date of the
acquisition, was allocated based on estimated fair values as follows (in
thousands):

         On June 12, 1997, the Company consummated an acquisition to purchase
the contract drilling assets of Wes-Tex Drilling Company ("Wes-Tex"), a
privately-held, non-affiliated company based in Abilene, Texas, for a purchase
price of approximately $35.4 million; consisting of $25 million in cash, 283,000
shares of Patterson common stock valued at $31.50 per share, which represented
the approximate fair market value on the date the terms of the acquisition were
agreed to and announced, a three-year stock purchase warrant (valued at $6.24
per share) to purchase 200,000 additional shares of Patterson common stock at an
exercise price of $32.00 per share and approximately $190,000 of other direct
costs incurred relative to the transaction. The acquisition was funded using
$19.0 million of the Company's cash on hand and $6.0 million provided by the
Company's $30.0 million line of credit. The assets acquired consisted of 21
contract drilling rigs, all related rolling stock and a shop and yard. The
purchase price, as of the date of acquisition, was allocated based on estimated
fair values as follows (in thousands):

         As the acquisitions of both Robertson and Wes-Tex are significant to
the Company's operations, the following summary for the three months ended March
31, 1997 and 1998, prepared on a pro forma basis, combines the consolidated
results of operations as if Robertson and Wes-Tex had been acquired on January
1, 1997, after including the impact of certain adjustments, such as restatement
of depreciation using the fair values instead of the book values of the assets
acquired, the increased interest expense on the acquisition debt, increased
amortization expense on intangible assets and the related income tax effects.

would have occurred if the acquisition had been in effect for the entire periods
presented. In addition, they are not intended to be a projection of future
results and do not reflect any synergies that might be achieved from combined
operations.

         The aforementioned acquisitions have been accounted for as purchases
and the results of operations and cash flows of the acquired entities have been
included in the unaudited condensed consolidated financial statements since the
date of acquisition. The purchase price allocations as detailed above are
preliminary in nature and subject to change.

3.       INTANGIBLE ASSETS

         Intangible assets as of the balance sheet date consist of covenants not
to compete and goodwill arising from the Company's acquisitions completed during
fiscal year 1997 and the three months ended March 31, 1998 (as described above
in Note 2). The covenants are being amortized on a straight line basis over
their contractual lives of five years. Goodwill, representing the excess of the
purchase price over the estimated fair value of the assets acquired, is being
amortized on a straight line basis over fifteen years.

         Intangible assets consisted of the following at March 31, 1998 (in
thousands):

                                                     =========
</TABLE>

         Management continually reviews the carrying amounts of goodwill for
recoverability based on the anticipated undiscounted cash flows of the assets to
which it relates. The Company considers operating results, trends and prospects
of the Company, as well as competitive comparisons. The Company also takes into
consideration competition within the industry and any other events or
circumstances which might indicate potential impairment. If goodwill is
determined to not be recoverable an impairment charge will be recognized to the
extent that the carrying value of the related assets, including goodwill,
exceeds the estimated fair value.

4.       NOTE PAYABLE

         During February 1998, the Company amended its loan agreement with
Norwest increasing its line of credit from $60 million to $70 million. The
Company's debt to tangible net worth ratio requirement increased from 1.2:1.0 to
1.50:1.00 and the Company's current ratio requirement increased from 1.25:1.00
to 1.40:1.00. In conjunction with the increased credit facility, the Company
paid a $25,000 origination fee.

5.       STOCKHOLDERS' EQUITY

         On December 8, 1997, Patterson's Board of Directors authorized a
two-for-one stock split in the form of a 100% stock dividend payable on January
23, 1998. The stockholders of Patterson, at a Special Meeting of Stockholders on
December 30, 1997, approved an amendment to Patterson's Certificate of
Incorporation increasing the number of authorized shares of common stock from
18,000,000 to 50,000,000. Par value of the Company's common stock remained at
$0.01 per common share. Accordingly, earnings per share and weighted average
number of common shares outstanding for all periods presented herein reflect the
effects of the stock split.

         During January 1998, the Company issued 571,328 shares of its common
stock as partial consideration for the Company's acquisition of Lone Star (See
Note 2). The common stock was valued at $17.41 per share for purposes of the
transaction.

6.       RECENT ACCOUNTING STANDARDS

         During the quarter ended March 31, 1998, the Company adopted Statement
of Financial Accounting Standards No. 130, "Reporting Comprehensive Income"
("Statement 130") which establishes standards for reporting and presentation of
comprehensive income and its components (revenues, expenses, gains and losses)
in a full set of general-purpose financial statements. Statement 130 requires
that all items that are required to be recognized under accounting standards as
components of comprehensive income be reported in a financial statement that is
displayed with the same prominence as other financial statements. Statement 130
requires that an enterprise (i) classify items of other comprehensive income by
their nature in a financial statement and (ii) display the accumulated balance
of other comprehensive income separately from retained earnings and additional
paid-in capital in the equity section of a statement of financial position. The
Company's adoption of Statement 130 did not result in any significant changes to
its related reporting disclosures.

         During the quarter ended March 31, 1998, the Company adopted Statement
of Financial Accounting Standards No. 131, "Disclosures About Segments of an
Enterprise and Related Information" ("Statement 131"). Statement 131 establishes
revised guidelines for determining an entity's operating segments and the type
and level of financial information to be disclosed. The Company's adoption of
Statement 131 did not result in any significant changes to its related reporting
disclosures.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
RESULTS OF OPERATIONS.

LIQUIDITY AND CAPITAL RESOURCES

         As of March 31, 1998, the Company had working capital of approximately
$41 million and cash and cash equivalents of approximately $16.3 million as
compared to a working capital of approximately $46.5 million and cash and cash
equivalents of approximately $23.3 million as of December 31, 1997. The decrease
in the Company's working capital at March 31, 1998 was largely attributable to
cash expended by the Company related to acquisitions completed during the three
months then ended. Approximately $5.1 million of the aggregate purchase price of
such acquisitions was funded using cash on hand at the respective dates of
acquisition. Additionally, as a result of the above mentioned transactions the
Company assumed approximately $3.4 million of debt which was subsequently paid
in full using cash on hand. For the three months ended March 31, 1998, the
Company generated net cash from operations of approximately $4.237 million,
received proceeds of approximately $208,000 from the exercise of stock options,
sold property and equipment for proceeds of approximately $159,000, received
approximately $566,000 from the sale of investment securities and borrowed
$40.15 million under an existing credit facility. These funds were used
primarily to acquire drilling and other related equipment and associated
intangible assets of approximately $48.390 million, to fund leasehold
acquisition, exploration and development of approximately $1.0 million and to
reduce certain notes payable by approximately $3.4 million.

         On January 5, 1998, the Company completed the acquisition of Lone Star
Mud, Inc. ("Lone Star"), a privately-owned, non-affiliated company based in
Midland, Texas for a purchase price of approximately $12.98 million consisting
of $1.430 million in cash, 571,328 shares of the Company's common stock valued
at $17.41 per share, which was the market price on the acquisition date, the
assumption of $1.6 million of debt and approximately $3,300 of direct costs
incurred related to the acquisition. Lone Star is a provider of drilling fluids
to the oil and natural gas industry. Management of the Company viewed the
acquisition as an opportunity to enter into a related segment of the oilfield
service industry, which would integrate well with the Company's existing
operations.

         On February 6, 1998, the Company completed its merger with Robertson
Onshore Drilling Company ("Robertson"), a privately owned, non-affiliated
contract drilling company based in Dallas, Texas. The purchase price of $42.245
million consisted of $3.25 million in cash, $36.75 million provided by the
Company's line of credit, the assumption of $1.8 million of debt and
approximately $444,000 of direct costs incurred related to the acquisition. As a
result of the merger, the Company acquired 15 operable drilling rigs, increasing
the Company's rig fleet to 114 drilling rigs, and a shop and yard located in
Liberty City, Texas.

         During February 1998, the Company amended its existing line of credit
agreement with Norwest Bank Texas, N.A. increasing the credit facility from $60
million to $70 million. Certain of the underlying covenants were amended;
however, the basic terms of the agreement remained unchanged. Currently, the
Company has $10 million of available credit facility remaining under the
agreement.

         Management believes that the current level of cash and short-term
investments, together with cash generated from operations should be sufficient
to meet the Company's immediate capital needs. From time to time, the Company
reviews acquisition opportunities relating to its business. The timing, size or
success of any acquisition and the associated capital commitments are
unpredictable. Should further opportunities for growth requiring capital arise,
the Company believes it would be able to satisfy these needs through a
combination of working capital, cash from operations, and either debt or equity
financing. However, there can be no assurance that such capital would be
available.

RESULTS OF OPERATIONS

Comparison of the three months ended March 31, 1998 and 1997

         For the three months ended March 31, 1998, contract drilling revenues
were approximately $54.3 million as compared to $27.6 million for the same
period in 1997; an increase of 97%. Average rig utilization was 70% for the
three months ended March 31, 1998, as compared to 86% for the same period in
1997. Direct contract drilling expenses for the three months ended March 31,
1998 were approximately $40 million, or 74% of the contract drilling revenues,
as compared to approximately $22.3 million, or 81% of the contract drilling
revenues, for the same period in 1997. The increase in contract drilling
revenues and direct contract drilling expenses is largely attributable to the
addition of 50 drilling rigs to the Company's operable drilling fleet since
April 1997. General and administrative expense for the contract drilling segment
was approximately $1.9 million for the three months ended March 31, 1998 as
compared to $1.0 million for the same period in 1997. The increase in general
and administrative expense for the three months ended March 31, 1998 was largely
attributable to the addition of the Dallas, Texas administrative office acquired
in the Company's merger with Robertson. As a result of the Company's
acquisitions, depreciation and amortization expense for the contract drilling
segment increased from approximately $2.2 million for the three months ended
March 31, 1997 to approximately $5.1 million for the same period in 1998. For
the three months ended March 31, 1998, operating income from this segment was
approximately $7.2 million as compared to approximately $2.157 million for the
same period in 1997.

         The Company derives substantially all of its operating revenues and
profit from its contract drilling operations; however, the Company realized
revenues from other operating activities of approximately $6.5 million for the
fiscal quarter ended March 31, 1998 as compared to $3.1 for the same quarter in
1997. The increase in the current year revenues was attributable to the
Company's addition of Lone Star during January 1998, which generated
approximately $4.3 million of from its drilling fluid services. For the quarter
ended March 31, 1998, the Company incurred operating costs of approximately $5.8
million related to its other operating activities, including approximately $1.1
million of depreciation, depletion and amortization and approximately $712,000
of general and administrative expense. This compares to operating costs of
approximately $2.5 million, including $1.1 million of depreciation, depletion
and amortization and approximately $337,000 of general and administrative
expense for the same period in 1997. Operating income from the Company's other
operating activities for the three months ended March 31, 1998 was approximately
$711,000 as compared to approximately $637,000 for the fiscal quarter ended
March 31, 1997.

         For the three months ended March 31, 1998, interest expense was
approximately $899,000 as compared to $483,000 for the same period in 1997. The
1997 interest expense amount includes approximately $265,000 of prepayment
penalties and fees incurred as a result of the Company's early retirement of its
notes payable during the first quarter of 1997 using proceeds provided by its
equity offering completed during that time. Interest income for the first three
months of 1998 was approximately $165,000 as compared to approximately $284,000
in 1997. The Company recognized a net gain on the sale of property and equipment
of approximately $159,000 for the three months ended March 31, 1998 as compared
to a net gain of approximately $135,000 for the same period in 1997.

         As a result of the Company's increased profitability and reduced
benefit of certain deferred tax assets, the Company incurred income tax expense
of approximately $2.8 million as compared to approximately $955,000 in 1997. As
previously reported, the Company fully reduced its valuation allowance existing
against its deferred tax assets in prior periods recognizing the related
benefit. To the extent the Company generates income in excess of its remaining
deferred tax assets, it will incur income tax expense at its effective statutory
rate.

VOLATILITY OF OIL AND NATURAL GAS PRICES AND ITS IMPACT ON OPERATIONS

         The Company's revenue, profitability and future rate of growth are
substantially dependent upon prevailing prices for oil and natural gas, both
with respect to its contract drilling and its oil and natural gas segments.
Historically, oil and natural gas prices and markets have been extremely
volatile. Prices are affected by market supply and demand factors as well as
actions of state and local agencies, the United States and foreign governments
and international cartels. All of these are beyond the control of the Company.
Any significant or extended decline in oil and/or natural gas prices will have a
material adverse effect on the Company's financial condition and results 




                                       15


<PAGE>   16

of operations. The sharp decline in crude oil prices beginning in the fourth
quarter of 1997 has adversely impacted the Company's operations. Should oil
prices remain at current levels or continue to decline or natural gas prices
begin to decline, the Company's operations could be further adversely affected.

IMPACT OF INFLATION

         The Company believes that inflation will not have a significant impact
on its financial position.

RECENT ACCOUNTING STANDARDS

         During the quarter ended March 31, 1998, the Company adopted Statement
of Financial Accounting Standards No. 130, "Reporting Comprehensive Income"
("Statement 130") which establishes standards for reporting and presentation of
comprehensive income and its components (revenues, expenses, gains and losses)
in a full set of general-purpose financial statements. Statement 130 requires
that all items that are required to be recognized under accounting standards as
components of comprehensive income be reported in a financial statement that is
displayed with the same prominence as other financial statements. Statement 130
requires that an enterprise (i) classify items of other comprehensive income by
their nature in a financial statement and (ii) display the accumulated balance
of other comprehensive income separately from retained earnings and additional
paid-in capital in the equity section of a statement of financial position. The
Company's adoption of Statement 130 did not result in any significant changes in
its reporting disclosures.

         During the quarter ended March 31, 1998, the Company adopted Statement
of Financial Accounting Standards No. 131, "Disclosures About Segments of an
Enterprise and Related Information" ("Statement 131"). Statement 131 establishes
revised guidelines for determining an entity's operating segments and the type
and level of financial information to be disclosed. The Company's adoption of
Statement 131 did not result in any significant changes in its reporting
disclosures.

YEAR 2000 COMPLIANCE PROGRAM

        The Company has conducted a review of its computer systems to identify
the systems that could be affected by the Year 2000 Issue (as defined below) and
has developed an implementation plan. The "Year 2000 Issue" is whether the
Company's computer systems will properly recognize date sensitive information
when the year changes to 2000, or "00." Systems that do not properly recognize
such information could generate erroneous data or cause a system to fail. The
Company uses purchased software programs for a variety of functions, including
general ledger, accounts payable and accounts receivable accounting packages.
The companies providing these software programs have represented that they are
Year 2000 compliant. The Company's Year 2000 implementation plan also includes
ensuring that all individual workstations are Year 2000 compliant. Costs
associated with ensuring the Company's systems are Year 2000 compliant are not
expected to be material to the Company's operations. Additionally, the Company
does not anticipate an interruption in its operations relative to Year 2000
concerns of its customers and vendors. The Company believes that the Year 2000
Issue will not pose significant operational problems for the Company's computer
systems and, therefore, will not have a significant impact on the operations of
the Company.

    CAUTIONARY STATEMENT FOR PURPOSES OF THE "SAFE HARBOR" PROVISIONS OF THE
                PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

         "Management's Discussion and Analysis of Financial Condition and
Results of Operations" included in Item 2 of this Report contains
forward-looking statements which are made pursuant to the "safe harbor"
provisions of The Private Securities Litigation Reform Act of 1995. These
statements include, without limitation, statements relating to: liquidity;
financing of operations; continued volatility of oil and natural gas prices;
source and sufficiency of funds required for immediate capital needs and
additional rig acquisitions (if further opportunities arise); and such other
matters. The words "believes," "plans," "intends," "expected" or "budgeted" and
similar expressions identify forward-looking statements. The forward-looking
statements are based on certain assumptions and analyses made by the Company in
light of its experience and its perception of historical trends, current
conditions, expected future developments and other factors it believes are
appropriate in the circumstances. The Company does not undertake to update,
revise or correct any of the forward-looking information. Factors that could
cause actual results to differ materially from the Company's expectations
expressed in the forward-looking statements include, but are not limited to, the
following: intense competition in the contract drilling industry; volatility of
oil and natural gas prices; market conditions for contract drilling services;
drill-pipe shortage; operational risks (such as blow outs, fires and loss of
production); labor shortage, primarily qualified drilling rig personnel;
insurance coverage limitations and requirements; potential liability imposed by
government regulation of the contract drilling industry (including environmental
regulation); the substantial capital expenditures required to fund its
operations; no assurance of additional growth through acquisitions; risk
associated with recent rapid growth; and the loss of key personnel, particularly
Cloyce A. Talbott and A. Glenn Patterson, the Chairman and Chief Executive
Officer and the President and Chief Operating Officer of the Company,
respectively. For a more complete explanation of these various factors, see
"Cautionary Statement for Purposes of the 'Safe Harbor' Provisions of the
Private Securities Litigation Reform Act of 1995" included in the Company's
Annual Report on Form 10-K for the year ended December 31, 1997, beginning on
