1.   BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

     The accompanying unaudited consolidated financial statements include the
accounts of Core Laboratories N.V. and have been prepared in accordance with
United States of America ("U.S.") generally accepted accounting principles
("GAAP") for interim financial information using the instructions to Form 10-Q
and Article 10 of Regulation S-X. Accordingly, they do not include all of the
information and footnotes required by GAAP for complete financial statements. In
the opinion of management, all adjustments considered necessary for a fair
presentation have been included. Operating results for the three-month period
ended March 31, 2002 are not necessarily indicative of the results that may be
expected for the year ending December 31, 2002. Balance sheet information as of
December 31, 2001 was derived from the 2001 annual audited financial statements.
These financial statements should be read in conjunction with the financial
statements and the summary of significant accounting policies and notes thereto
included in our Form 10-K for the year ended December 31, 2001.

Recent Pronouncements

     In June 2001, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standard ("SFAS") 143, "Accounting for Asset
Retirement Obligations." SFAS 143 addresses financial accounting and reporting
for obligations associated with the retirement of long-lived assets and the
associated asset retirement costs. SFAS 143 requires that the fair value of a
liability associated with an asset retirement be recognized in the period in
which it is incurred if a reasonable estimate of fair value can be made. The
associated retirement costs are capitalized as part of the carrying amount of
the long-lived asset and subsequently depreciated over the life of the asset.
SFAS 143 will be effective for fiscal years beginning after December 31, 2002.
We do not expect SFAS 143 to have a material adverse effect on our financial
position or results of operations.

     In August 2001, the FASB issued SFAS 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets." SFAS 144 addresses the financial accounting and
reporting for the impairment or disposal of long-lived assets. SFAS 144
supersedes SFAS 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed of." SFAS 144 provides updated guidance
concerning the recognition and measurement of an impairment loss for certain
types of long-lived assets and modifies the accounting and reporting of
discontinued operations. SFAS 144 is effective for fiscal years beginning after
December 31, 2001. We do not expect SFAS 144 to have a material adverse effect
on our financial position or results of operations.

     In November 2001, the Emerging Issues Task Force ("EITF") staff issued
Topic D-103, "Income Statement Characterization of Reimbursements Received for
"Out-of-Pocket" Expenses Incurred." As a result, customer reimbursements,
including those relating to travel and other out-of-pocket expenses and other
similar third-party costs, will be required to be included as revenues effective
January 1,

                                       4


2002, and an equivalent amount of reimbursable expenses will be
included in expenses. We do not expect EITF Topic D-103 to have an impact on our
financial position or results of operations.


2.   INVENTORIES

     Inventories consist of manufactured goods, materials and supplies used for
sales or services provided to customers. Inventories are stated at the lower of
average or standard cost (includes direct material, labor and overhead) or
estimated net realizable value, and are reflected net of valuation reserves of
$1,824,000 and $1,847,000 at March 31, 2002 and December 31, 2001. Respectively,
inventories consisted of the following (in thousands):

                                               March 31,         December 31,

3.   BUSINESS COMBINATIONS, INTANGIBLES AND GOODWILL

     Intangibles include patents, trademarks, service marks and trade names.
Goodwill represents the excess of purchase price over the value of the net
assets and individual intangibles acquired in acquisitions accounted for as
purchases. Intangibles are charged to expense in equal amounts over their
estimated useful lives.

     In June 2001, the FASB issued two statements, SFAS 141, "Business
Combinations", and SFAS 142, "Goodwill and Other Intangible Assets", that amend
Accounting Principles Board ("APB") Opinion No. 16, "Business Combinations", and
supersede APB Opinion No. 17, "Intangible Assets." SFAS 141 eliminates the
pooling-of-interests method of accounting for business combinations and
establishes the purchase method of accounting as the only acceptable method on
all business combinations initiated after June 30, 2001. Goodwill resulting from
a business combination after June 30, 2001 was recognized as an asset but not
amortized, while goodwill existing at June 30, 2001 was amortized through
December 31, 2001. Beginning January 1, 2002, we no longer amortize goodwill but
will test for impairment annually or more frequently if circumstances indicate a
potential impairment. We determined our reporting unit level to be our operating
units. Using the discounted cash flow method under the requirements of SFAS 142,
we have reflected impairment of goodwill of approximately $16.7 million related
to our Reservoir Management Segment as a result of adoption of SFAS 142 on
January 1, 2002. This impairment is reflected in the statement of operations as
a cumulative effect of change in accounting principle. The cessation of goodwill
amortization under the guidelines will result in a reduction of approximately
$4.2 million in annual operating expenses, assuming no additional impairment of
goodwill. The components of intangibles and goodwill are as follows:

equivalency of $5 million. At March 31, 2002, approximately $81 million was
available for borrowing under the revolving credit facility. Loans under the
Credit Facility bear interest from LIBOR plus 1.25% to a maximum of LIBOR plus
1.75%. The average interest rate in effect at March 31, 2002 was 3.51% and the
average for 2002 was 3.33%. The revolving credit facilities require interest
payments only, until maturity in June 2004.

     In July 1999, we issued $75 million in Senior Notes which bear an average
interest rate of 8.16% and require annual principal payments beginning in July
2005 and continuing through July 2011.

     The terms of the Credit Facility and Senior Notes require us to meet
certain financial covenants, including certain minimum equity and cash flow
tests. We believe that we are in compliance with all such covenants contained in
our credit agreements. All of our material wholly owned subsidiaries are
guarantors or co-borrowers under both credit agreements.

5.   RESTRUCTURING CHARGES

     During the fourth quarter of 2001, we had several transactions which
impacted certain operations that were not viewed as ongoing. We restructured
certain operations in Mexico, the United Kingdom, the U.S. and other countries
to improve operating efficiencies. This restructuring expense included
write-offs of assets and leasehold improvements, and an accrual for facility
restoration, severance benefits and lease termination costs. Approximately 100
field employees were terminated. During 2002, we intend to relocate one of our
operations from Dallas to the Houston Advanced Technology Center and another
facility from Mexico City, Mexico to Villahermosa, Mexico. This charge of
approximately $3.0 million affected each of our operating segments as follows:
Reservoir Description - $0.8 million; Production Enhancement - $0.1 million;
Reservoir Management - $2.1 million. Substantially all employee terminations
were completed by the end of the first quarter of 2002. Total cash required for
this restructuring charge of $2.1 million will be funded from operating
activities. Cash required for the costs incurred through March 31, 2002 was $0.9
million. This charge is summarized in the following table:

1) The fixed assets and leasehold improvements were disposed of by the end of
December 2001. The write-off approximates the carrying amount as these assets
were abandoned or sold for salvage value. Depreciation expense was reduced by
approximately $20 in 2001, and will be reduced by $82 in 2002 and $281
thereafter. The asset write-offs of $862 were attributable to the Reservoir
Management segment.

6.   SEGMENT REPORTING

     Our business units have been aggregated into three complementary segments
which provide products and services for improving reservoir performance and
increasing oil and gas recovery from new and existing fields.

o        Reservoir  Description:  Encompasses the characterization of petroleum
         reservoir rock, fluid and gas samples.  We provide analytical and field
         services to characterize properties of crude oil and petroleum products
         to the oil and gas industry.

o        Production Enhancement: Includes products and services relating to
         reservoir well completions, perforations, stimulations and production.
         We provide integrated services to evaluate the effectiveness of well
         completions and to develop solutions aimed at increasing the
         effectiveness of enhanced oil recovery projects.

                                      7



o        Reservoir Management: Combines and integrates information from
         reservoir description and production enhancement services to increase
         production and improve recovery of oil and gas from our clients'
         reservoirs.


Segment Analysis

     We manage our business segments separately due to the different
technologies each segment utilizes and requires. Results of these segments are
presented below using the same accounting policies as used to prepare the
Consolidated Balance Sheets and Statements of Operations. We evaluate
performance based on income or loss from operations before income tax, interest
and other non-operating income (expense). Summarized financial information
concerning our segments is shown in the following table (in thousands):

7.   EARNINGS PER SHARE

     We present earnings per share in accordance with SFAS No. 128, "Earnings
per Share" which requires dual presentation of both basic and diluted earnings
per share on the Consolidated Statement of Operations. Basic earnings per common
share is computed by dividing net income available to common stockholders by the
weighted average number of common share outstanding during the period. Diluted
earnings per share reflects the net additional shares which would be issued if
all dilutive stock options outstanding were exercised.

                                       8



     The following table summarizes the calculation of weighted average common
shares outstanding used in the computation of earnings per share:

                             CORE LABORATORIES N.V.
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS


General

     This discussion includes forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933 and Section 21E of the
Securities Exchange Act of 1934. We have based the forward-looking statements
relating to our operations on our current expectations, estimates and
projections. We caution you that these statements are not guarantees of future
performance and involve risks and uncertainties that we cannot predict. In
addition, we have based many of these forward-looking statements on assumptions
about future events that may prove to be inaccurate. Accordingly, our actual
outcomes and results may differ materially from what we have expressed or
forecast in the forward-looking statements. Our forward-looking statements are
based on assumptions that we believe to be reasonable but that may not prove to
be accurate. All of our forward-looking information is, therefore, subject to
risks and uncertainties that could cause actual results to differ materially
from the results expected. Although it is not possible to identify all factors,
these risks and uncertainties include the risk factors discussed below.

     Industry risks

     The oil and gas industry is highly cyclical and there are numerous
factors affecting the supply of and demand for oil and natural gas, which
include:

o        market prices of oil and gas;
o        cost of producing oil and natural gas;
o        the level of drilling and production activity;
o        mergers, consolidations and downsizing among our clients;
o        coordination by the OPEC; and
o        the impact of commodity prices on the expenditure levels of our
         customers.

     Business risks

     Our results of operations could be adversely affected by risks and
uncertainties in the business environment in which we operate, including:

o        competition in our markets;
o        the realization of anticipated synergies from acquired businesses and
         future acquisitions; o our ability to continue to develop or acquire
         new and useful technology; and
o        interest rates and the cost of capital.

     International risks

     We conduct our business in over 50 countries and are subject to
political and economic instability and the laws and regulations in the countries
in which we operate. These include:

                                       10



o        global economic conditions;
o        political actions and requirements of national governments including
         trade restrictions, and embargos and expropriations of assets;
o        potential income tax liabilities in multiple jurisdictions;
o        civil unrest;
o        fluctuations and changes in currency exchange rates; and
o        the impact of inflation.

     Other risks

     The events of September 11, the economic downturn and political events
that followed and continue to unfold could result in lower demand for our
products and services. Our client base could be impacted by events we cannot
predict or we could be impacted by a change in the conduct of business,
transportation and security measures. In addition we are subject to other risk
factors such as the impact of environmental regulations, litigation risks as
well as the dependence on the oil and gas industry. Many of these risks are
beyond our control. In addition, future trends for pricing, margins, revenues
and profitability remain difficult to predict in the industries we serve and
under current economic and political conditions. We do not feel obligated to
publicly update any of our forward-looking statements.

     Our operations are subject to various risk and other factors including,
but not limited to:

o       our ability to continue to develop or acquire new and useful technology.
o       the realization of anticipated synergies from acquired businesses and
        future acquisitions.
o       our dependence on the oil and gas industry, and the impact of commodity
        prices on the expenditure levels of our customers.
o       competition in our markets.
o       the risks and uncertainties attendant to adverse industry, political,
        economic and financial market conditions, including stock prices,
        government regulations, interest rates and credit availability.

     Core Laboratories was established in 1936 and is one of the world's leading
providers of proprietary and patented reservoir description, production
enhancement and reservoir management services to the oil and gas industry. These
services are directed toward enabling our clients to improve reservoir
performance and increase oil and gas recovery from their producing fields. We
have over 70 offices in more than 50 countries and have approximately 4,200
employees.

Results of Operations

     Service revenues for the first quarter of 2002 decreased $3.9 million, or
5% from the same period last year, primarily due to decreased worldwide oilfield
activities.

     Cost of services expressed as a percentage of service revenue were 79% and
77% in the first quarter of 2002 and the same period last year, respectively.
Our relatively fixed cost structure for our services caused our cost of
services, in relation to revenues, to rise in the first quarter of 2002 compared
to same time period in the prior year.

                                       11



     Sales revenues decreased to $15.5 million in the first quarter of 2002 from
$17.8 million in the first quarter of 2001, a 13% decrease. This decrease was
caused, in most part, to the deep decline in drilling for natural gas in the
North American markets. Consequently, there was lower demand for our well
completion products.

     Cost of sales in the first quarter of 2002 was 90% of sales revenue as
compared to 85% the same period last year. We have taken further actions,
including reducing headcount an additional 15%, in our manufacturing operations
in an effort to reduce cost of sales.

     General and administrative expenses are comprised of corporate management
and centralized administrative services which benefit our operating
subsidiaries. Although general and administrative expenses are generally more
fixed in nature as a percentage of revenues, we did experience an increase of
$1.1 million in 2002 compared to the prior year which was largely attributable
to growth in the number of people necessary to support increases in the scope of
our operations. Part of the increase was due to an increase in our direct
marketing effort focused on providing integrated solutions to our clients.

     Depreciation and amortization expense for the first quarter of 2002
increased $0.4 million as compared to the corresponding period in 2001. This
increase was due to additional capital investments, which include an extension
to the new Houston facility.

     As a result of adoption of SFAS 142 beginning January 1, 2002, we no longer
amortize goodwill but will test for impairment annually or more frequently if
circumstances indicate a potential impairment. Under the requirements, we have
reflected impairment of goodwill of approximately $16.7 million related to our
Reservoir Management segment. This impairment is reflected in the statement of
operations as a cumulative effect of a change in accounting principle. The
cessation of goodwill amortization under the guidelines will result in a
reduction of approximately $4.2 million in annual operating expenses, assuming
no additional impairment of goodwill.

     Included in other income are foreign exchange charges of $0.9 million
primarily related to Venezuela.

     The effective income tax rate remained at 28% for both periods.

     During the fourth quarter of 2001, we had several transactions which
impacted certain operations that were not viewed as ongoing. We restructured
certain operations in Mexico, the United Kingdom, the U.S. and other countries
to improve operating efficiencies. This restructuring expense included
write-offs of assets and leasehold improvements, and an accrual for facility
restoration, severance benefits and lease termination costs. Approximately 100
field employees were terminated. During 2002, we intend to relocate one of our
operations from Dallas to the Houston Advanced Technology Center and another
facility from Mexico City, Mexico to Villahermosa, Mexico. This charge of
approximately $3.0 million affected each of our operating segments as follows:
Reservoir Description - $0.8 million; Production Enhancement - $0.1 million;
Reservoir Management - $2.1 million. Substantially all employee terminations
were completed by the end of the first quarter of 2002. Total cash required for
this restructuring charge of $2.1 million will be funded from operating
activities. Cash required for the costs incurred through March 31, 2002 was $0.9
million. This charge is summarized in the following table:

         1) "Corporate and Other" represents those items that are not directly
            related to a particular segment.


Reservoir Description

     Revenues from the Reservoir Description segment increased $1.5 million in
the first quarter of 2002. Increased international demand for our existing
services and deepwater services, as well as the introduction of new technologies
into international arenas, bolstered revenue in this segment. Income before
interest and taxes decreased by $1.1 million due to decreased margins due to
seasonal slowness and the reduced worldwide economic activity causing a negative
impact on our crude oil and petroleum product characterization unit.

                                       13


Production Enhancement

     Revenues from the Production Enhancement segment were $23.4 million in the
first quarter of 2002 compared to $26.8 million in the same period in the prior
year, a decrease of 13%, due to decreased demand for our well completion and
stimulation technologies; primarily in North American markets. Income before
interest and taxes decreased $2.9 million to $0.9 million, a 76% decrease, again
caused by the severity of the reduction in activity. The rig count in North
America dropped by 38% compared to the corresponding period in the prior year.

Reservoir Management

     Revenues from the Reservoir Management segment in the first quarter of 2002
were $12.0 million, a decrease of $4.4 million compared to the same period in
the prior year due to decreasing activity levels of our clients and our decision
not to attain business with unacceptable earnings' margins. Despite this
decrease in revenue our income before interest and taxes remained at a constant
level, as we were able to significantly reduce our cost structure in this unit
after taking the restructuring charge in the fourth quarter of 2001.

Liquidity and Capital Resources

     We have historically financed our activities through cash flows from
operations, bank credit facilities, equity financing and the issuance of debt.

     During the first quarter of 2002, cash flows from operating activities were
$6.0 million, a decrease of $2.4 million from the same period in 2001. At March
31, 2002, we had working capital of $142.5 million and a current ratio of 5.7 to
1.0, compared to working capital of $139.3 million and a current ratio of 4.5 to
1.0 at December 31, 2001. We are a Netherlands holding company and we conduct
substantially all of our operations through subsidiaries. Consequently, our cash
flow is dependent upon the ability of our subsidiaries to pay cash dividends or
otherwise distribute or advance funds to us.

     Our investing activities used $4.2 million in the first quarter of 2002
compared to $5.4 million in the same period in 2001 due to a reduction in our
capital expenditure program. Our financing activities used $0.8 million in the
first quarter of 2002, and $1.8 million in the same period in 2001.

     Our ability to maintain and grow our operating income and cash flows is
dependent upon continued investing activities. We believe our future cash flows
from operations, supplemented by our borrowing capacity and issuances of
additional equity should be sufficient to fund debt requirements, capital
expenditures, working capital and future acquisitions.

             QUANTITATIVE AND QUALITATIVE DISCLOSURES OF MARKET RISK

Market Risk

     We are exposed to market risk, which is the potential loss arising from
adverse changes in market prices and rates. We do not enter, or intend to enter,
into derivative financial instruments for trading or speculative purposes. We do
not believe that our exposure to market risks, which are primarily related to
interest rate changes and fluctuations in foreign exchange rates, are material.
During 1999, we issued fixed rate Senior Notes denominated in U.S. dollars. The
proceeds were used to pay off variable rate term loans. This significantly
reduced our exposure to market risk. This section should be read in conjunction
with "Note 4 - Long-Term Debt" of the Notes to Consolidated Financial
Statements.

Interest Rate Risk

     We are exposed to interest rate risk on our Credit Facility debt that
carries a variable interest rate. At March 31, 2002, our variable rate debt
outstanding of $19.0 million approximated its fair value. A one percent change
in the interest rate would not cause a material change in interest expense on an
annual basis. We attempt to balance the benefit of variable rate debt that has
inherent increased risk with fixed rate debt that has less market risk.

Item 1.     Legal Proceedings.
