                        REPORT OF INDEPENDENT ACCOUNTANTS


To the Participants and Administrator of
Core Laboratories Profit Sharing and Retirement Plan


In our opinion, the accompanying statement 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 Core Laboratories Profit Sharing and Retirement Plan (the "Plan") at December
31, 2001, and the changes in net assets available for benefits for the year then
ended 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 audit. We conducted our audit 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
audit provides a reasonable basis for our opinion. The financial statements of
the Plan as of December 31, 2000 and for the year then ended were audited by
other independent accountants whose report dated June 25, 2001 expressed an
unqualified opinion on those statements.

Our audit was conducted 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 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 audit 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.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS





To the Plan Administrator of the
Core Laboratories, Inc. Profit Sharing
and Retirement Plan:

We have audited the accompanying statements of net assets available for plan
benefits of the Core Laboratories, Inc. Profit Sharing and Retirement Plan (the
"Plan") as of December 31, 2000 and 1999, and the related statement of changes
in net assets available for plan benefits for the year ended December 31, 2000.
These financial statements and the supplemental schedule referred to below are
the responsibility of the Plan Administrator. Our responsibility is to express
an opinion on these financial statements and supplemental schedule based on our
audits.

We conducted our audits in accordance with auditing standards generally accepted
in the 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 plan benefits of the Plan as
of December 31, 2000 and 1999, and the changes in net assets available for plan
benefits for the year ended December 31, 2000, in conformity with accounting
principles generally accepted in the United States.

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) as of December 31, 2000, 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 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.

1.  SUMMARY OF SIGNIFICANT PLAN PROVISIONS:

The Core Laboratories Profit Sharing and Retirement Plan (the "Plan" or "Core
Lab Plan") was established by Core Laboratories LP (the "Company"), effective
October 1, 1994. Effective May 1, 2001, the Plan was amended to reflect a change
in the Company's name and legal status from Core Laboratories, Inc. to Core
Laboratories LP. The Plan's new name is the Core Laboratories Profit Sharing and
Retirement Plan. The following description of key features of the Plan provides
only general information. Participants should refer to the Plan document, as
amended, for a more complete explanation of the Plan's provisions.

Plan Administrator and Trustee

The Company is the Plan administrator as defined under the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"). The Company contracts with
The 401K Company (the "Recordkeeper") to maintain the Plan's participant account
balances. Austin Trust Company (the "Trustee") is the trustee of all investments
held by the Plan. The issuing fund houses are custodians of the mutual fund
investments and the Pershing Division of Donaldson, Lufkin & Jenrette Securities
Corporation is custodian of Core Laboratories N.V. common stock ("Company Common
Stock").

Eligibility

Substantially all of the Company's employees, including temporary or part-time
employees who have completed at least 1,000 hours of service in a Plan year, are
eligible to participate in the Plan. Employees who are active participants in
another qualified plan sponsored by the company and employees of Owen Oil Tools
LP with less than six months of service are ineligible to participate.
Participation may commence upon the later of the first day of the calendar
quarter coincident with or following such eligible employee's date of hire or
the date on which such employee attains the age of 21.

Contributions

The Plan allows participants to contribute up to 15 percent of their
compensation, as defined by the Plan, on a pretax basis. At its discretion, the
Company makes matching contributions to the account of each participant up to
four percent of each participant's compensation. The Company may, at its
discretion, also contribute for a Plan year an additional amount with respect to
each participant who has completed one year of service and is employed by the
Company on the last day of such Plan year. The Company's board of directors
shall determine whether such contribution shall be made for a Plan year. No
additional contributions were made to the Plan for 2001.

Vesting

Participants are fully vested in their contributions and related earnings/losses
and vest in Company contributions and related earnings/losses at the rate of 20
percent for each year of service. Upon death, total and permanent physical or
mental disability, or normal retirement, all such participants become fully
vested in Company contributions and related earnings/losses.





Investment Program

Participants may invest their contributions, the Company's matching
contributions and any additional Company contributions in any of ten mutual
funds, one collective trust fund and Company Common Stock.

Contributions may be invested in one fund or divided among two or more funds.
Participants may transfer some or all of the balances out of any fund into one
or any combination of the other funds on a daily basis. Participants who are
seeking guidance in their investment direction can choose from four Asset
Allocation Models: Short-Term Model (1-5 years); Medium-Term Model (5-10 years);
Long-Term Model (10-15 years) or Longer-Term Model (15+ years) which represent a
designated blend of the available mutual funds. Participants who select one of
the Asset Allocation Models can also choose to invest a portion of their account
balances in the Company Common Stock.

Administrative Expenses

The Plan pays all administrative expenses.

Loans

The Plan permits participants to borrow a minimum of $1,000 up to a maximum
amount equal to the lesser of $50,000 or 50 percent of their vested account
balances in the Plan. New loans bear interest at treasury rates plus four
percent and are repaid through payroll deductions over a period not to exceed
five years.

Withdrawals and Forfeitures

A participant may elect to receive benefit payments through any one of the
several methods provided by the Plan upon termination, retirement or financial
hardship. Participants can withdraw their after-tax contributions, if any from
previous plans, in cash without being suspended from making additional
contributions to the Plan. Participants may also make an in-service withdrawal
at age 59 1/2 of their vested account balance. Participants may elect an in-kind
distribution of Core Laboratories N.V. stock in lieu of cash upon termination,
retirement or upon electing an in-service withdrawal at age 59 1/2.

Hardship withdrawals are allowed in the event of immediate and heavy financial
need, subject to the provisions of the Internal Revenue Code of 1986, as amended
(the "Code"). The participants can withdraw up to 100 percent of their pre-tax
contributions and are suspended for at least 12 months from making additional
contributions to the Plan.

Upon termination of employment with the Company, any unvested Company
contributions and related earnings/losses are forfeited. Participants returning
to the Company within 60 months of their initial termination are entitled to
have their previous account balance reinstated by the Company. During 2001,
$223,934 of forfeited balances were utilized to reduce the Company's
contributions. At December 31, 2001 and 2000, forfeited amounts of $77,840 and
$215,684, respectively, were available to reduce future employer contributions
or Plan expenses.

Priorities Upon Plan Termination

Although it has not expressed any intent to do so, the Company has the right
under the Plan to discontinue its contributions at any time and to terminate the
Plan subject to the provisions of ERISA. In the event of Plan termination,
participants will become 100 percent vested in their accounts.







2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Basis of Accounting

The financial statements of the Plan are prepared on the accrual basis of
accounting in accordance with accounting principles generally accepted in the
United States. Distributions to participants are recorded when paid.

Investment Valuation

Pursuant to the Department of Labor Rules and Regulations for Reporting and
Disclosure under ERISA, the Plan reports the investments in the financial
statements at fair value in accordance with accounting principles generally
accepted in the United States.

Investments in mutual funds and common stock are reported at fair value based on
quoted market prices. The fair value of the investment in the collective trust
fund is based on the market value of the underlying assets, as determined by the
investment issuer. The collective trust fund holds investment contracts which
are recorded at contract value, which approximates fair value. The average yield
of the collective trust fund for the year ended December 31, 2001, was 6.49
percent. Investment income is recorded as earned. Purchases and sales are
recorded on a trade-date basis.

Net realized gains or losses on the sale of investments and unrealized
appreciation (depreciation) in the fair value of investments are recorded in the
accompanying statement of changes in net assets available for plan benefits as
net appreciation (depreciation) in fair value of investments.

Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires the use of estimates and
assumptions that affect the accompanying financial statements and disclosures.
Actual results could differ from those estimates.

4.   RISKS AND UNCERTAINTIES:

The Plan provides for various investments in a collective trust fund, mutual
funds and common stock. Investment securities, in general, are exposed to
various risk, such as interest rate, credit and overall market volatility risks.
Due to the level of risk associated with certain investment securities, it is
reasonably possible that changes in the values of investment securities will
occur in the near term.


5.   TAX STATUS:

The Plan obtained its latest determination letter on November 12, 1996, in which
the Internal Revenue Service stated that the Plan, as then designed, was in
compliance with the applicable requirements of the Code. The Plan has been
amended since receiving the determination letter. However, the Company believes
that the Plan is currently designed and being operated in compliance with the
applicable requirements of the Code. Therefore, the Company believes that the
Plan was qualified and tax-exempt as of December 31, 2001 and 2000.
