   99.1   Certification accompanying Annual Report pursuant to Section 906 of
          the Sarbanes-Oxley Act of 2002 executed by Steven J. Shapiro, on
          behalf of Burlington Resources Inc. Benefits Committee, the

                         REPORT OF INDEPENDENT AUDITORS



To the Participants and Administrator of
Burlington Resources Inc. Retirement Savings Plan


In our opinion, the accompanying statements of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of Burlington Resources Inc. Retirement Savings Plan (the "Plan") at December
31, 2002 and 2001, and the changes in its net assets available for benefits for
the year ended December 31, 2002, in conformity with accounting principles
generally accepted in the United States of America. These financial statements
are the responsibility of the Plan's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States of America which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule listed in the
accompanying table of contents is presented for the purpose of additional
analysis and is not a required part of the basic financial statements but is
supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in the audits of the basic financial statements and, in our
opinion, is fairly stated in all material respects in relation to the basic
financial statements taken as a whole.

NOTES TO FINANCIAL STATEMENTS

--------------------------------------------------------------------------------


1.       PLAN DESCRIPTION

         The following description of the Burlington Resources Inc. ("BR" or the
         "Company") Retirement Savings Plan (the "Plan") provides only general
         information. Participants should refer to the Plan Document for a more
         complete description of the Plan's provisions.

         GENERAL

         The Plan is a trusteed, defined contribution plan, administered by a
         committee of BR executives, for participants of the employer companies
         BR and Burlington Resources Oil & Gas Company LP (formerly known as
         Burlington Resources Oil & Gas Company), which is a wholly-owned
         subsidiary of BR. The Plan is subject to the provisions of the Employee
         Retirement Income Security Act of 1974 ("ERISA"), as amended. The
         Plan's assets are held by Charles Schwab Trust Company and individual
         participant accounts are maintained by Charles Schwab Retirement Plan
         Services.

         INVESTMENTS

         A participant may direct his or her contributions and account balances
         among the following investment funds.

         Company Stock Fund

         Invested in common stock of BR.

         S&P 500 Institutional Index Fund

         Invested in a portfolio of common stock and other equity securities.
         This fund is managed to achieve results similar to those of the overall
         stock market as measured by the Standard & Poor's 500 Index.

         International Equity Fund

         Invested primarily in the equity securities of companies based outside
         the United States of America.

         Balanced Fund

         Invested in equity securities, which attempt to mirror the Willshire
         5000 Equity Index and in high-quality bonds, which attempt to mirror
         the Lehman Brothers Aggregate Bond Index.

         Small-Cap Equity Fund

         Invested in common stocks, or other equity securities including
         preferred stocks, rights and warrants of the second 1,000 largest U.S.
         corporations.

         Growth Equity Fund

         Invested primarily in common stocks of corporations that the trust
         advisor believes are undervalued and capable of generating strong
         earnings growth in the near term.

         Large Capital Value Fund

         Invested primarily in common stocks and other instruments convertible
         into common stock issued by large corporations.

BURLINGTON RESOURCES INC. RETIREMENT SAVINGS PLAN
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2002
--------------------------------------------------------------------------------


         Global Equity Fund

         Invested primarily in equity instruments issued by corporations from
         the U.S. and abroad.

         Stable Value Fund

         Invested primarily in a diversified portfolio of investment contracts
         offered by major insurance companies and financial institutions.

         Small Cap Growth Fund

         Invested primarily in common stocks of U.S. and foreign companies
         within the range of capitalizations of companies included in the
         Lipper, Inc. Small Cap category.

         ELIGIBILITY

         All employees are eligible to participate in the Plan beginning the
         first day of the month following full time employment, or upon
         completion of 1,000 hours of service.

         PARTICIPANT ACCOUNTS

         A separate account is maintained for each participant that reflects the
         participant's contributions and the participant's share of Company
         contributions and Plan investment income net of withdrawals. Each
         participant can authorize the transfer of account balances among funds
         or change investment options for future contributions.

         Appreciation (depreciation) is allocated to participants based upon
         their proportionate share of assets in each investment fund.

         PARTICIPANTS' NOTES RECEIVABLE

         The Plan may make loans to actively employed participants of up to 50
         percent of their account balance (excluding any remaining Individual
         Retirement Account balance that was entered into prior to 1998),
         subject to a minimum loan of $1,000 and a maximum loan of $50,000. The
         $50,000 limit is reduced by the participant's highest outstanding loan
         balance during the prior one-year period. Loans are secured by the
         balance in a participant's account. Interest on loans accrues at 1
         percent above the Wall Street Journal published prime rate, which is
         determined at the time the loan is taken, and remains fixed for the
         term of the loan. Interest rates ranged from 5.25 percent to 10.50
         percent for the year ended December 31, 2002. The repayment period may
         be from 12-60 months. Repayments are made through payroll deductions
         and are reinvested in Plan funds according to the borrowing
         participant's current investment elections. Loan balances due from
         terminated participants are deemed distributed to the participants
         during the quarter following the quarter in which the last loan payment
         was made. During 2002, $397,251 of such distributions are included in
         participant withdrawals and distributions in the accompanying financial
         statements.

         There were no loans in default as of December 31, 2002 and 2001.

         CONTRIBUTIONS

         A participant may elect to make regular semi-monthly pre-tax and/or
         after-tax contributions from 1 percent to 13 percent of his or her
         total eligible compensation via regular payroll deduction. Pre-tax
         contributions are subject to an Internal Revenue Service (IRS)
         limitation of $11,000 for the 2002 plan year. The Company matches 100
         percent of employee contributions up to 6 percent of total eligible
         compensation for a participant with less than 10 years of service and
         up


                                        5


BURLINGTON RESOURCES INC. RETIREMENT SAVINGS PLAN
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2002
--------------------------------------------------------------------------------


         to 8 percent of total eligible compensation for a participant with 10
         or more years of service. In addition, a participant may make an
         approved rollover contribution from another qualified employee benefit
         plan, subject to IRS rules. All regular Company and participant
         contributions are paid to the Plan's trustee semi-monthly, and
         allocated among the investment options consistent with participant
         investment elections.

         VESTING

         Participant accounts are 100 percent vested and nonforfeitable at all
         times.

         PARTICIPANT WITHDRAWALS AND DISTRIBUTIONS

         The Plan provides for in-service withdrawals by participants from
         certain funds depending on their source. Upon separation from service,
         a participant's account balance is either distributed as a lump sum or
         deferred until 70-1/2, at which time funds are to be distributed in a
         lump sum. A participant whose account balance exceeds $5,000 may elect
         to defer distribution until 70-1/2 but no later.

         TERMINATION OF THE PLAN

         While the Board of Directors of BR has not expressed any intention to
         do so, it may at any time terminate the Plan. Upon termination, the
         Plan's assets will be distributed to the participants on the basis of
         their account balances existing at the date of termination.

         INCOME TAXES

         The Plan received a determination letter dated October 25, 2002, from
         the IRS advising that the Plan constitutes a qualified plan under
         Section 401(a) of the Internal Revenue Code, and is therefore, exempt
         from income taxes.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         BASIS OF ACCOUNTING

         In accordance with generally accepted accounting principles ("GAAP"),
         the accounting records of the Plan are maintained on the accrual basis,
         except for participant withdrawals and distributions, which are
         reported when paid. Amounts for benefit claims that have been processed
         and approved for payment prior to December 31, but not paid as of that
         date, are reported on Form 5500 as withdrawals. No such unpaid claims
         exist at December 31, 2002 or 2001.

         USE OF ESTIMATES

         The preparation of the Plan's financial statements in conformity with
         GAAP requires certain estimates and assumptions by Plan management.
         Actual results could differ from estimates.

         RISKS AND UNCERTAINTIES

         Due to the level of risk associated with certain investment securities
         and the level of uncertainty related to changes in their value, it is
         at least reasonably possible that changes in the near term could
         materially affect the amounts reported in the Statement of Net Assets
         Available for Benefits.

--------------------------------------------------------------------------------


         VALUATION OF INVESTMENTS

         The Plan's investments, except for its investment contracts, are stated
         at fair value. Investment contracts, which are fully benefit
         responsive, are stated at contract value. Fair values for investments
         other than participants' notes receivable and cash are determined by
         quoted market prices. Participants' notes receivable are carried at
         original loan principal balance, less principal repayments, which
         approximates fair value. Cash is stated at account value. Investment
         transactions are recorded on a settlement date basis.

         CASH AND CASH EQUIVALENTS

         All short-term investments purchased with an original maturity of three
         months or less are considered cash equivalents. Cash equivalents are
         stated at fair value.

         DIVIDEND AND INTEREST INCOME

         Dividend and interest income from investments are recorded as earned
         and allocated to participants based upon their proportionate share of
         assets in each investment fund.

         ADMINISTRATIVE EXPENSES

         Certain administrative expenses and professional fees incurred by the
