Item 2.           Acquisition or Disposition of Assets

           On August 1, 1997, Stone Energy Corporation (the "Company") closed
the purchase of certain interests in Vermilion Block 255 Field (the "Property")
from three entities for $36.6 million. The sellers were Aviara Energy
Corporation, Forest Oil Corporation and TOTAL Minatome Corporation. The field
consists of interests in four Vermilion blocks (255, 256, 267 and 268), and the
working interests acquired range from 66.7% to 83.3%. The effective date of the
acquisition was April 1, 1997, and net cash flow from the property from April
through July 1997, estimated at $2.4 million, will be recorded as a reduction of
the investment in the property.

           Eight platforms and 48 wells exist on the field, with 10 wells
currently producing at the aggregate daily rates of approximately 1,500 barrels
of oil and 18 million cubic feet of gas. Stone Energy is now the field operator,
and the remaining interests in the property are owned by CNG Producing Company.
In addition to the purchase price, Stone Energy provided a bond in the amount of
$8.8 million to secure abandonment obligations.

           The Company funded the purchase of the Property with an advance under
its line of credit with a bank group led by NationsBank of Texas, N.A.

                          INDEPENDENT AUDITORS' REPORT



The Board of Directors
Stone Energy Corporation:



We have audited the accompanying statement of revenues and direct operating
expenses of Aviara Energy Corporation's Interest in the Vermilion Block 255
Field for the year ended December 31, 1996, acquired by Stone Energy
Corporation. This financial statement is the responsibility of Stone Energy
Corporation's management. Our responsibility is to express an opinion on this
financial statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the statement of revenues and direct operating expenses
is free of material misstatement. An audit of a statement of revenues and direct
operating expenses includes examining, on a test basis, evidence supporting the
amounts and disclosures in that financial statement. An audit of a statement of
revenues and direct operating expenses also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audit of the statement of revenues and direct operating expenses provides a
reasonable basis for our opinion.

The accompanying statement of revenues and direct operating expenses was
prepared for the purpose of complying with the rules and regulations of the
Securities and Exchange Commission and excludes material expenses, described in
note 1 to the financial statement, that would not be comparable to those
resulting from the proposed future operations of the oil and gas properties and
is not intended to be a complete presentation of revenues and expenses.

In our opinion, the statement of revenues and direct operating expenses referred
to above presents fairly, in all material respects, the revenues and direct
operating expenses of Aviara Energy Corporation's Interest in the Vermilion
Block 255 Field as described in note 1 for the year ended December 31, 1996 in
conformity with generally accepted accounting principles.

                       NOTES TO STATEMENT OF REVENUES AND
                            DIRECT OPERATING EXPENSES
                      FOR THE YEAR ENDED DECEMBER 31, 1996

1.       BASIS OF PRESENTATION:

The accompanying financial statement presents the revenues and direct operating
expenses of Aviara Energy Corporation's ("Aviara") interest in the Vermilion
Block 255 Field ("Properties")for the year ended December 31, 1996. These
properties were purchased by Stone Energy Corporation ("Stone") effective April
1, 1997 for approximately $13.7 million. The Properties consist of royalty and
working interests in the Vermilion Block 255 Field (which includes interests in
Vermilion Blocks 255, 256, 267 and 268).

The accompanying statement of revenues and direct operating expenses of the
Properties does not include general and administrative expenses, interest
expense, depreciation, depletion and amortization, or any provision for income
taxes since historical expenses of this nature incurred by Aviara are not
necessarily indicative of the costs to be incurred by Stone.

Revenues in the accompanying statement of revenues and direct operating expenses
are recognized on the sales method. Direct operating expenses are recognized on
the accrual basis and consist of monthly operator overhead costs and other
direct costs of operating the Properties which were charged to the joint account
of working interest owners by the operators of the wells.

Historical financial information reflecting financial position, results of
operations, and cash flows of the Properties is not presented because the
purchase price was assigned to the oil and gas property interests and related
equipment acquired. Other assets acquired and liabilities assumed were not
material. In addition, the Properties were a part of a much larger enterprise
prior to acquisition by Stone and representative amounts of general and
administrative expenses, depreciation, depletion and amortization, interest and
other indirect costs were not necessarily allocated to the Properties acquired,
nor would such allocated historical costs be relevant to future operations of
the Properties. Development and exploration expenditures related to these
Properties were insignificant in the relevant period. Accordingly, the
historical statement of revenues and direct operating expenses of Aviara's
Interest in the Vermilion Block 255 Field is presented in lieu of the financial
statements required under Item 3-05 of Securities and Exchange Commission
Regulation S-X.

The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.

2.       SUPPLEMENTARY FINANCIAL INFORMATION FOR OIL AND GAS PRODUCING 
         ACTIVITIES (UNAUDITED):


The following reserve estimates present Stone's estimate of the proved oil and
gas reserves and net cash flow of the properties, all of which are off-shore
United States properties. Stone emphasizes that reserve estimates are inherently
imprecise 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. The estimates have been prepared
by Stone's petroleum reservoir engineers.

(A)      RESERVE QUANTITY INFORMATION

Below are the net quantities of proved reserves and proved developed reserves
of the Properties.

                                                   Oil                Gas

                                              =============      =============

(B)      STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO 
         PROVED OIL & GAS RESERVES:

The Standardized Measure of Discounted Future Net Cash Flows Relating to Proved
Oil and Gas Reserves ("Standardized Measure") is a disclosure requirement under
Statement of Financial Accounting Standards No. 69.

The Standardized Measure of discounted future net cash flows does not purport to
be, nor should it be interpreted to present, the fair value of the oil and gas
reserves of the properties. An estimate of fair value would also take into
account, among other things, the recovery of reserves not presently classified
as proved, the value of unproved properties, and consideration of expected
future economic and operating conditions.

                      FOR THE YEAR ENDED DECEMBER 31, 1996


The estimates of future cash flows and future production and development costs
are based on period-end sales prices for oil and gas, estimated future
production of proved reserves, and estimated future production and development
costs of proved reserves, based on current costs and economic conditions. The
estimated future net cash flows are then discounted at a rate of 10%.

Estimates of economically recoverable gas and oil reserves and of future net
revenues are based upon a number of variable factors and assumptions, all of
which are to some degree speculative and may vary considerably from actual
results. Therefore, actual production, revenues, development and operating
expenditures may not occur as estimated. The reserve data are estimates only,
are subject to many uncertainties and are based on data gained from production
histories and on assumptions as to geologic formations and other matters. Actual
quantities of gas and oil may differ materially from the amounts estimated.

                               NOTE -- UNAUDITED

        The above presented Statement of Revenues and Direct Operating Expenses
for the six months ended June 30, 1997 is unaudited; however, it includes
all adjustments (consisting only of normal recurring adjustments) which, in the
opinion of Stone Energy Corporation's management, are necessary for a fair
presentation for such periods. Accounting measurements at interim dates
inherently involve greater reliance on estimates than at year end. The results
of operations for the interim periods presented are not necessarily indicative
of the results to be expected for the entire year.

        Certain footnote disclosures normally included in annual consolidated
financial statements prepared in accordance with generally accepted accounting
principles have been omitted herein. The interim information should be read in
conjunction with the accompanying annual financial statements and notes.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To the Stockholder and Board of Directors of
TOTAL Minatome Corporation:



We have audited the accompanying statement of historical oil and gas revenues
and direct operating expenses relating to TOTAL Minatome Corporation's interest
in the Vermilion 255 Field (see Note 1) for the year ended December 31, 1996.
This statement is the responsibility of the Company's management. Our
responsibility is to express an opinion on this statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the statement of historical oil and gas revenues and
direct operating expenses is free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the statement. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

In our opinion, the statement of historical oil and gas revenues and direct
operating expenses referred to above presents fairly, in all material respects,
the historical oil and gas revenues and direct operating expenses relating to
the Company's interest in the Vermilion 255 Field for the year ended December
31, 1996, in conformity with generally accepted accounting principles.

                      FOR THE YEAR ENDED DECEMBER 31, 1996


 1.       THE VERMILION 255 FIELD:

On July 2, 1997, TOTAL Minatome Corporation (TMC) and its partners in the
Vermilion 255 Field entered into a purchase and sale agreement (the Agreement)
to sell their interests in certail oil and gas properties and related assets
(collectively, the Vermilion 255 Field or the properties) to Stone Energy
Corporation (Stone). The purchase price at the effective date of April 1, 1997
was subject to certain adjustments (as defined in the Agreement) between the
effective date and the closing date of August 1, 1997. TMC's share of the net
purchase price at the closing date was approximately $13.7 million. The purchase
price is subject to future adjustments not previously determined, up to 120 days
after the closing date.

2.         BASIS OF PRESENTATION:

During the period presented, the above property was not accounted for or
operated as a separate division by TMC. Certain costs, such as depreciation,
depletion and amortization, general and administrative expenses, and corporate
income taxes were not allocated to the individual properties. Accordingly,
complete separate financial statements prepared in accordance with generally
accepted accounting principles do not exist and are not practicable to obtain in
these circumstances.

Revenues and direct operating expenses for the oil and gas properties included
in the accompanying statement represent TMC's interest in the properties and are
presented on the accrual basis of accounting and may not be representative of
future operations. The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of revenues and direct
operating expenses during the reporting period. Actual results could differ from
those estimates.

3.      COMMITMENTS AND CONTINGENCIES:

Pursuant to the terms of the Agreement, liability for certain claims, litigation
or disputes pending as of the effective date and certain matters arising in
connection with ownership of the properties prior to the effective date is
retained by TMC.

                  OIL AND GAS PRODUCING ACTIVITIES - UNAUDITED



Reserve information presented below is based on the December 31, 1996 reserve
report prepared in accordance with guidelines established by the Securities and
Exchange Commission ("SEC"). Accordingly, the following reserve estimates are
based upon existing economic and operating conditions at the respective dates.

There are numerous uncertainties inherent in estimating quantities of proved
reserves and in providing the future rates of production and timing of
development expenditures. The following reserve data represents estimates only
and should not be construed as being exact. In addition, the present values
should not be construed as the current market value of the related oil and gas
properties or the cost that would be incurred to obtain equivalent reserves.

The following table sets forth Stone's analysis of TOTAL Minatome Corporation's
("TMC") share of the Vermilion 255 Field estimated quantities of net proved and
proved developed oil (including condensate) and gas reserves:

The following tables present Stone's analysis of TMC's share of the standardized
measure of future net cash flows related to proved oil and gas reserves together
with changes therein, as defined by the Financial Accounting Standards Board.
The oil, condensate and gas price structure utilized to project future net cash
flows reflects current prices at each year end. Future production and
development costs are based on current costs with no escalations. Estimated
future cash flows have been discounted to their present values based on a 10%
annual discount rate.

                          INDEPENDENT AUDITORS' REPORT



BOARD OF DIRECTORS
FOREST OIL CORPORATION:


We have audited the accompanying statement of oil and gas revenue and direct
lease operating expenses of certain oil and gas properties (the Forest
Properties) of Forest Oil Corporation (FOC) acquired by Stone Energy Corporation
for the year ended December 31, 1996. This financial statement is the
responsibility of FOC's management. Our responsibility is to express an opinion
on this financial statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the statement of oil and gas revenue and direct lease
operating expenses is free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the statement of oil and gas revenue and direct lease operating expenses. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

The accompanying statement of oil and gas revenue and direct lease operating
expenses was prepared for the purpose of complying with the rules and
regulations of the Securities and Exchange Commission and excludes material
expenses, described in Note 1 to the financial statement, that would not be
comparable to those resulting from the proposed future operations of the oil and
gas properties, as described in Note 1 and is not intended to be a complete
presentation of the Forest Properties' revenue and expenses.

In our opinion, the statement of oil and gas revenue and direct lease operating
expenses referred to above presents fairly, in all material respects, the oil
and gas revenue and direct lease operating expenses of the Forest Properties as
described in Note 1 for the year ended December 31, 1996, in conformity with
generally accepted accounting principles.

1.      PURCHASE OF OIL AND GAS PROPERTIES AND BASIS OF PRESENTATION:

The accompanying financial statement presents the revenues and direct operating
expenses of certain oil and gas properties and related equipment of Forest Oil
Corporation (Forest Properties) for the year ended December 31, 1996. These
properties were purchased by Stone Energy Corporation (Stone) effective April 1,
1997 for approximately $6.52 million. The properties consist of revenue and
working interests in oil and gas properties located offshore, in the Gulf of
Mexico.

The accompanying statement of oil and gas revenue and direct lease operating
expenses of the Forest Properties was prepared to comply with certain rules and
regulations of the Securities and Exchange Commission and does not include
general and administrative expenses, interest expense, a provision for
depreciation, depletion and amortization, or any provision for income taxes
since historical expenses of this nature incurred by Forest Oil Corporation are
not necessarily indicative of the costs to be incurred by Stone.

Revenue in the accompanying statement of oil and gas revenue and direct lease
operating expenses is recognized on the sales method. Direct lease operating
expenses are recognized on the accrual basis and consist of monthly
administrative overhead costs, production taxes, and other direct costs of
operating the Forest Properties.

2.      SUPPLEMENTARY FINANCIAL INFORMATION FOR OIL AND GAS PRODUCING ACTIVITIES
        (UNAUDITED):
        (A)  RESERVE QUANTITY INFORMATION

The following table presents Stone's estimate of the proved oil and gas reserves
attributable to the Forest Properties, all of which are located in the United
States. Stone emphasizes that reserve estimates are inherently imprecise 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. The estimates have been prepared by Stone's
petroleum reservoir engineers.

(B)  STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO
      PROVED OIL AND GAS RESERVES:

The Standardized Measure of Discounted Future Net Cash Flows Relating to Proved
Oil and Gas Reserves (Standardized Measure) is a disclosure requirement under
Statement of Financial Accounting Standards No. 69.

The Standardized Measure of discounted future net cash flows does not purport to
be, nor should it be interpreted to present, the fair value of the oil and gas
reserves of the properties. An estimate of fair value would also take into
account, among other things, the recovery of reserves not presently classified
as proved, the value of unproved properties, and consideration of expected
future economic and operating conditions.

Future oil and gas sales and production and development costs have been
estimated using prices and costs in effect at the end of the year. Future income
tax expense has not been considered as the properties are not a tax paying
entity. Future general and administrative and interest expenses have also not
been considered.

Estimates of economically recoverable gas and oil reserves and of future net
revenues are based upon a number of variable factors and assumptions, all of
which are to some degree speculative and may vary considerably from actual
results. Therefore, actual production, revenues, development, and operating
expenditures may not occur as estimated. The reserve data are estimates only,
are subject to many uncertainties and are based on data gained from production
histories and on assumptions as to geologic formations and other matters. Actual
quantities of gas and oil may differ materially from the amounts estimated.

                            STONE ENERGY CORPORATION
                               NOTES TO PRO FORMA
                        CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


NOTE 1 -  BASIS OF PRESENTATION

         On August 1, 1997, Stone Energy Corporation (the "Company") closed the
purchase of certain interests in Vermilion Block 255 Field (the "Property") from
three entities for $36.6 million. The sellers were Aviara Energy Corporation,
Forest Oil Corporation and TOTAL Minatome Corporation. The field consists of
interests in four Vermilion blocks (255, 256, 267 and 268), and the working
interests acquired range from 66.7% to 83.3%. The effective date of the
acquisition was April 1, 1997, and net cash flow from the property from April
through July 1997, estimated at $2.4 million, will be recorded as a reduction of
the investment in the property.

         Eight platforms and 48 wells exist on the field, with 10 wells
currently producing at the aggregate daily rates of approximately 1,500 barrels
of oil and 18 million cubic feet of gas. Stone Energy is now the field operator,
and the remaining interests in the property are owned by CNG Producing Company.
In addition to the purchase price, Stone Energy provided a bond in the amount of
$8.8 million to secure abandonment obligations.

         The pro forma consolidated balance sheet at June 30, 1997 and the
related pro forma consolidated statement of operations for the year ended
December 31, 1996 and the six months ended June 30, 1997 have been prepared
assuming that the Property acquisition was consummated on January 1, 1996. The
preparation of the combined pro forma financial statements is based on certain
adjustments to the historical financial statements of the Company and the
historical statements of revenues and direct operating expenses of the Property
and are not necessarily indicative of the financial position or results of
operations had the above described property acquisition occurred on the assumed
date. These pro forma financial statements should be read in conjunction with
the financial statements of the Property included in this Form 8-K/A and of the
Company contained in the Company's Annual Report on Form 10-K for the year ended
December 31, 1996 and Quarterly Report on Form 10-Q for the period ended June
30, 1997.

NOTE 2 - PRO FORMA ADJUSTMENTS

         Pro forma entries necessary to adjust the historical financial
statements are as follows:

                (a) To record net purchase price of the Property and related
                borrowings under Company's credit facility and interest expense
                at the bank's prime rate.

                (b) To adjust depreciation, depletion and amortization amounts
                on a historical basis

                been included in the financial statements effective January 1,
                1996.

                (c) To record a provision for Federal and state income taxes at
                a corporate statutory rate of 38.5%.
