      measure to the net debt-to-capital ratio provided in our conference call
      is debt-to-equity, which is calculated as total long-term debt divided by
      equity. Debt-to-equity, as calculated, is 40.2% versus 23.3% for net
      debt-to-capital at December 31, 2005.</font></td>

      <b>Return on Equity:
      </b>The calculation for return on equity is earnings before

      Management utilizes return on equity in evaluating how much profit the
      Company generates on the shareholders' equity in the Company and is useful
      for comparing the profitability of companies in the same industry. Had we used net income in the
      calculation of return on equity, which represents the most comparable GAAP
      measure, return on equity for the year ended December 31, 2005 would have
      been 14.6% versus 35.3%.</font></td>

Item 2.02 Results of Operations and Financial Condition
On February 15, 2006, Core Laboratories N.V. issued a press release
announcing its 2005 fourth quarter and full year financial results. The
full text of the press release including
certain updates as noted below is set forth in Exhibit 99 attached hereto and is
incorporated in this Report as if fully set forth herein.
In addition to financial results
determined in accordance with generally accepted accounting principles (GAAP)
that are included in the attached press release, certain other non-GAAP financial measures (as defined under the SEC's
Regulation G) were used in the press release and subsequent conference call:
Non-GAAP
      Financial Measures Included In Press Release
*
Net Income Before Impact of Equity-Based Stock Compensation Plans and Debt
      Prepayment Charge; or Earnings From Continuing Operations Before Costs
      Associated With the Prepayment of Senior Notes and Expenses Related to Two
      EBSCP:
Management
      believes that the exclusion of certain expenses and credits enables it to
      evaluate more effectively the Company's operations period over period and
      to identify operating trends that could otherwise be masked by the
      excluded items.  For this reason, we used certain the non-GAAP of these
      measures that excluded these non-recurring items and explained in the same sentence how they relate to the
      most directly comparable GAAP measure;
      we felt that presentation provides the public a clearer comparison with the numbers reported
      in prior quarters.
*
Operating Earnings Before
      Impact of Equity-Based Stock Compensation Plans
:
Management believes that the exclusion of
      certain expenses and credits enables it to evaluate more effectively the
      Company's operations period over period and to identify operating trends
      that could otherwise be masked by the excluded items.
*
Incremental Operating
      Margins:
Incremental operating margins is
      computed as (1) the increase or decrease in income from continuing
      operations before equity-based stock compensation, interest expense and income tax expense between two
      periods, divided by (2) the increase or decrease in revenues between the
      same two periods. Management believes that incremental margins provide
      useful information regarding the growth over the two periods being
      compared.
*
Free Cash Flow:
Free cash flow is an important measurement as it represents
      the cash from operations before the impact of the debt prepayment charge, in excess of capital expenditures, available to
      operate the business and fund non-discretionary obligations.
Non-GAAP
      Financial Measures Included In Conference Call In Addition To Those Listed
      Above
*
Net Debt-to-Capital:
Net debt-to-capital is calculated as long-term debt
      less cash divided by the sum of shareholders' equity plus long-term debt
      plus cash. Management
      believes this capital structure ratio can provide a more accurate view of
      a company's long-term leverage and risk, since it considers only long-term
      debt and capital.
The most comparable GAAP
      measure to the net debt-to-capital ratio provided in our conference call
      is debt-to-equity, which is calculated as total long-term debt divided by
      equity. Debt-to-equity, as calculated, is 40.2% versus 23.3% for net
      debt-to-capital at December 31, 2005.
*
Return on Equity:
The calculation for return on equity is earnings before
      equity-based stock compensation,
      interest expense and tax expense divided by shareholders' equity.
      Management utilizes return on equity in evaluating how much profit the
      Company generates on the shareholders' equity in the Company and is useful
      for comparing the profitability of companies in the same industry. Had we used net income in the
      calculation of return on equity, which represents the most comparable GAAP
      measure, return on equity for the year ended December 31, 2005 would have
      been 14.6% versus 35.3%.
The following have been updated from the issued press release:
The Company disclosed operating income for the Twelve Months Ended December 2005
in the Reconciliation of Operating Income as $60,391 which has been updated to
reflect $60,931.

Core uses the non-GAAP measure of free cash flow to evaluate its cash flows and results of operations.  Free cash flow is an important measurement because it represents the cash from operations
before the impact of the debt prepayment charge, in excess of capital expenditures, available to operate the business and fund non-discretionary obligations.

net income, cash flows or other measures of financial performance prepared in
accordance with GAAP as more fully discussed in Core Laboratories financial
statements and filings with the Securities and Exchange Commission.
