             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Employee Benefits Committee and Participants
Noble Energy, Inc. Thrift and Profit Sharing Plan:

We have audited the accompanying statements of net assets available for benefits
of the Noble Energy, Inc. Thrift and Profit Sharing Plan (the Plan) as of
December 31, 2003 and 2002, and the related statements of changes in net assets
available for benefits for the years then ended. 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 in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards 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. 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 audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Noble
Energy, Inc. Thrift and Profit Sharing Plan as of December 31, 2003 and 2002,
and the changes in its net assets available for benefits for the years then
ended, in conformity with accounting principles generally accepted in the United
States of America.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) is presented for purposes 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. The
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.

                NOBLE ENERGY, INC. THRIFT AND PROFIT SHARING PLAN

                          Notes to Financial Statements

                           December 31, 2003 and 2002

(1)   DESCRIPTION OF THE PLAN

      The Noble Energy, Inc. Thrift and Profit Sharing Plan (the Plan), as
      amended, is a defined contribution plan covering certain employees who
      have completed specified terms of service with Noble Energy, Inc.,
      formerly Noble Affiliates, Inc., and its wholly owned subsidiaries
      (collectively referred to as the Company). The Plan is subject to the
      provisions of the Employee Retirement Income Security Act of 1974 (ERISA),
      as amended.

      The following description of the Plan provides only general information.
      Participants should refer to the plan document for a complete description
      of the Plan's provisions.

      Employees are eligible to participate in the Plan on the first day of any
      calendar month following employment. Participants may contribute up to 15%
      of their basic compensation, subject to annual limitation established by
      the Internal Revenue Service (IRS). The employer matching contribution
      percentage is 100% of the participant's contribution up to 6% of the
      participant's basic compensation and is funded subsequent to each pay
      period. However, discretionary contributions may be made to the Plan at
      the discretion of the President of the Company.

      The Plan is to continue indefinitely; however, the right to terminate
      participation in the Plan is reserved to each participating company. Upon
      notice of termination or permanent suspension of contributions with
      respect to all or any one of the participating companies, the accounts of
      all participants affected thereby shall become fully vested, and the
      balances in their accounts shall be distributed in accordance with the
      provisions of the Plan, as determined by the Noble Energy, Inc. Employee
      Benefits Committee (the Committee).

      The Plan is exempt from federal income taxes under Sections 401 and 501(a)
      of the Internal Revenue Code and has received a favorable determination
      letter from the IRS dated March 8, 2003. Therefore, management of the
      Company is of the opinion that the Plan meets IRS requirements and
      continues to be tax-exempt.

      The Plan incorporates the following provisions: (1) participants fully
      vest after three years of service (prior to January 1, 2002, participants
      vested after five years of service), (2) participants may borrow from the
      Plan, as discussed below, (3) overtime is included in the participant's
      basic compensation, and (4) the Plan provides a definition of early
      retirement. On termination of service due to death, disability,
      retirement, or other reasons, a participant will receive a lump-sum amount
      equal to the value of the participant's vested interest in his or her
      account.

      Participating employees have an option as to the manner in which their
      contributions may be invested. Employer contributions are invested as
      designated by the participants in the individual funds.

      A participant may borrow from the Plan up to the lesser of $50,000 or
      one-half of the participant's vested account balance. Interest is charged
      at the current prime rate and loans are required to be repaid within five
      years through payroll deductions. Repayments of principal and interest are
      credited to the borrowing participant's account.

      The Plan is administered by the Committee. Investment decisions are
      recommended by a professional investment advisory firm appointed by the
      Committee.

(2)   SIGNIFICANT ACCOUNTING POLICIES

      The accompanying financial statements are prepared on the accrual basis of
      accounting in conformity with accounting principles generally accepted in
      the United States of America.

      (a)   USE OF ESTIMATES

            The preparation of financial statements in conformity with
            accounting principles generally accepted in the United States of
            America requires management to make estimates and assumptions that
            affect the reported amounts of assets and liabilities and disclosure
            of contingent assets and liabilities at the date of the financial
            statements and the reported amounts of revenues and expenses during
            the reporting period. Actual results could differ from those
            estimates.

      (b)   INVESTMENTS

            Investments traded on national securities exchanges are valued at
            closing prices on the last business day of the year. Investments are
            accounted for on a trade-date basis. Participant loans and cash are
            valued at cost, which approximates fair value.

            Fidelity Investments Institutional Operations Company, Inc.
            (Fidelity) is the trustee of the Plan. Under the terms of the Plan,
            Fidelity (the Trustee), on behalf of the trust fund, is allowed to
            acquire, hold, and dispose of the common stock of Noble Energy, Inc.

            As of December 31, 2003 and 2002, the Plan held the following
            investments which separately represented more than 5% of the Plan's
            net assets available for benefits:

                NOBLE ENERGY, INC. THRIFT AND PROFIT SHARING PLAN

                          Notes to Financial Statements

                           December 31, 2003 and 2002

      (c)   EXPENSES OF THE PLAN

            Some expenses and fees incurred in the administration of the Plan
            are charged to and paid by the Plan. The remaining expenses and fees
            are paid by the Company including expenses and fees of the trustee.

      (d)   FORFEITURES

            Under the provisions of the Plan, all amounts forfeited as of the
            end of that year may be applied to reduce required employer
            contributions. Forfeitures amounted to $14,439 and $31,660 in 2003
            and 2002, respectively, and reduced the required employer
            contributions.

      (e)   RISKS AND UNCERTAINTIES

            The Plan may invest in various types of investment securities.
            Investment securities are exposed to various risks, such as interest
            rate, market, and credit risks. Due to the level of risk associated
            with certain investment securities, it is at least reasonably
            possible that changes in the values of investment securities will
            occur in the near term and that such changes could materially affect
            the amounts reported in the statements of net assets available for
            benefits.

(3)   NET APPRECIATION (DEPRECIATION) IN FAIR VALUE

      During 2003 and 2002, the Plan's investments, including investments
      bought, sold, and held during the year, appreciated (depreciated) in value
      as follows:



                                                        2003          2002

                                                     ----------   ----------
     Net appreciation (depreciation) in fair value   $9,549,800   (5,135,168)
                                                     ==========   ==========


      Realized gains (losses) are calculated based on proceeds from the sale of
      assets and the fair value of the assets at the beginning of the Plan year
      or at time of purchase if acquired during the current Plan year.
      Unrealized appreciation (depreciation) of investments is calculated based
      on the fair value of the assets at the end of the Plan year and the fair
      value of the assets at the beginning of the Plan year or at time of
      purchase if acquired during the current Plan year. Purchases and sales of
      investments are recorded on a trade-date basis.
