CORE LAB OPERATIONS POST EPS OF $0.29 FOR Q3 2004;
SEQUENTIAL QUARTERLY REVENUE GROWTH EXCEEDS 6%

AMSTERDAM (27 October 2004) - Core Laboratories' (NYSE: "CLB") continuing operations posted third quarter 2004 earnings of $0.29 per diluted share equaling the highest quarterly earnings per share ever reported by the Company. Net income from continuing operations was $8,234,000. Third quarter revenues reached $108,779,000, an all-time quarterly high, up over 6% sequentially from second quarter 2004 levels and up 11% over third quarter revenues of a year ago. Third quarter 2004 operating margins were over 12%, up over 100 basis points sequentially from second quarter 2004 margins, with sequential quarterly incremental margins of 30%, excluding the impact of performance-based stock compensation expense. Net cash provided by continuing operations was $13,309,000 for the quarter. The Company's record quarterly results were due to ongoing internationally-based Reservoir Description projects, the increased demand for new Core Lab technology, services and products recently introduced by Production Enhancement operations, and the increasing growth and success of several recently introduced Reservoir Management studies.

For the first nine months of 2004, revenues, earnings per diluted share, net income, and net cash from operating activities of Core's continuing operations were among the highest ever posted for the first three quarters by the Company. Revenues reached a record $311,327,000, up 14% over revenues for the first three quarters of 2003. Earnings per diluted share for continuing operations were $0.64, up from $0.43 for the same nine-month period in 2003. Net income from continuing operations for the first three quarters of 2004 increased 36% to $18,481,000 while cash provided by continuing operations was $36,858,000.

"Core Laboratories' commitment to develop new technologies and services to optimize reservoir performance and maximize hydrocarbon recovery has resulted in all-time record quarterly and nine-month financial results," said Chairman, President, and CEO David M. Demshur. "We remain uniquely focused on helping our clients produce the incremental barrel equivalent of oil, thereby increasing the net present value and cash flow from their producing assets. The prospect of incremental production from existing fields is generating new levels of interest as worldwide spare productive capacity has recently dropped to historical lows. This new dynamic, coupled with our global network, positions Core for additional growth in a world of tighter energy supplies."

Reservoir Description

Reservoir Description operations posted revenues of $63,649,000 and profit of $7,402,000 yielding operating margins of 12%. Sequentially, quarterly operating margins increased over 70 basis points. Large-scale Reservoir Description projects continued in Europe, the Middle East, West Africa, and Asia-Pacific. Demand for reservoir fluid phase-behavior studies and analytical characterization of refined products in European operations was strong during the quarter. The Middle East reservoir studies are primarily related to expanding crude-oil production while limiting water production from existing fields. Deepwater reservoir projects offshore West Africa involve characterizing complex, semi-consolidated sandstone formations to establish the most effective and efficient production programs, and several Asia-Pacific studies are establishing petrophysical and reservoir fluid databases that will be used to design future enhanced recovery programs. Many of the Asia-Pacific projects h ave recently increased in scope in response to higher crude oil prices and increased returns for oil companies producing incremental barrels of oil.

Production Enhancement

Production Enhancement operations posted third quarter 2004 revenue of $39,409,000, its all-time quarterly record, and operating profit of $5,053,000, its second highest quarterly total in Company history. Year-over-year quarterly revenue grew 24%, while sequential quarterly revenue growth exceeded 19%. Sequential quarterly incremental margins reached 23%.

The record results were due to increased market acceptance and penetration of Core's proprietary and patented SpectraFlood™ and SpectraChem™ services and High Efficiency Reservoir Optimization (HERO™) perforating charges and gun systems. The SpectraFlood service, a new technology for evaluating the effectiveness of field floods, is currently being used in Mexico, the United States, and Nigeria. The new SpectraChem technology for evaluating near-wellbore clean-up of frac fluids, has been employed in several stimulations in Louisiana, Texas, and New Mexico. HERO perforating charges and gun systems, which minimize formation damage when wellbore casing is perforated, are now being utilized in shallow to medium-depth natural gas producing provinces in Canada, the United States, and Mexico.

Reservoir Management

Reservoir Management generated its third straight profitable quarter with revenues of $5,721,000 and operating profit of $900,000. Sequentially, quarterly revenue increased 23% while operating margins reached 16%. The introduction of several new integrated regional engineering and geological studies contributed to the results. The Petroleum Geology of Libya, which evaluates cores and drill cuttings samples from over 75 wells from the onshore portions of the Sirte, Murzuq, and Ghadames basins, now has 20 company participants. Core will be extending the study to include offshore Libya in the first quarter of 2005.

A regional study of the Natural Gas Reservoirs of the Western Anadarko and Arkoma Basins is now underway and has been very well received by the industry. Also, in the United States, the Eocene Provenance Study in the Gulf of Mexico has received strong interest and participation. Petrophysical, sedimentological, and mineralogical data sets from core and cuttings samples will be used to project reservoir quality for deep-shelf and deepwater Eocene targets. Recent deepwater discoveries in the Mississippi Fan and Perdido fold belts in the Alaminos Canyon and Walker Ridge blocks provide evidence of prolific Eocene potential in a wide area of the deepwater Gulf of Mexico.

Stock Repurchase Program

Core continued its Share Repurchase Program during the third quarter by buying approximately 407,000 shares in open-market purchases. Since the inception of the Share Repurchase Program in October 2002, Core has repurchased over 7,670,000 shares at an average price of approximately $14.60. Currently, Core has approximately 26,247,000 shares outstanding and 28,870,000 diluted weighted average shares outstanding. To date, Core has invested over $112,000,000 in the Stock Repurchase Program, maintaining an industry average net debt-to-capitalization ratio. During the quarter the Company also paid down revolver debt to $42,000,000 from $44,000,000 at the end of the second quarter of 2004.

Fourth Quarter 2004 Targets

For the fourth quarter of 2004, Core expects revenue from continuing operations to be approximately $108,000,000 to $113,000,000, with earnings from those operations to range from $0.29 to $0.31 per diluted share. The Company expects fourth quarter 2004 net cash provided by continuing operations to be approximately $15,000,000.

Core is currently reviewing its operating plans for 2005 and believes it is too early to issue 2005 revenue and earnings guidance. However, the Company has finalized its capital expenditure budget for 2005 and expects it to range from $13,000,000 to $15,000,000, similar to 2004 levels.

The Company has scheduled a conference call to discuss this quarter's earnings announcement. The call will begin at 7:30 a.m. CDT on Thursday, 28 October, 2004. To listen to the call, please go to Core's website at www.corelab.com.
