The operating result of the second quarter 2002 is a profit of Euros 9.8 million compared to a profit of Euros 12.7 for the second quarter of 2001.This operating income is a profit of Euros 11.8 million before a loss of € 2 million from the sale of the equity held by CGG in Paradigm Geophysical. The operating result for the Geophysical Services segment for the second quarter is a Euros 1.7 million profit compared to a loss of Euros 4.4 million for the same quarter in 2001. Operating income from Sercel is a Euros 15.5 millions profit compared to Euros 21.0 million for the comparable period of 2001. Taking into account the provision of Euros 2 million, operating profit for the Products segment is Euros 13.5 million in the second quarter of 2002.

The operating result for the first half of 2002 is a Euros 16.9 million profit, increasing 18% compared to the first half of 2001. The operating result for the Geophysical Services for the first half of 2002 is a profit of Euros 1.9 million compared to a loss of Euros 11.6 million in the first half of 2001. The operating profit for Sercel for the first half of 2002 is a profit of Euros 27.3 million compared to a profit of Euros 32.9 million in the first half of 2001. The operating profit for the Products segment is a profit of Euros 25.3 million.

The net Group consolidated result for the second quarter of 2002 is a profit of Euros 5.9 million compared to a profit of Euros 1.0 million for the second quarter of 2001. The net result for the first half of 2002 is a Euros 0.3 million profit, compared to a Euros 5.1 million loss for the first half of 2001.

In the second quarter of 2002 Operating revenues for our Geophysical Services segment were Euros 125.5 million, up 4% when compared to the same period last year.

     Land SBU. In the second quarter of 2002, operating revenues for our Land SBU were Euros 47.5 million, 15% lower than the second quarter of 2001 and increasing sequentially by 35% compared to the first quarter of the year which marked a low point in this sector of activity. On average, 16 crews were in operation during the second quarter of 2002. The current backlog level indicates a sustained level of operations for the second half of the year 2002.

     Offshore SBU. Operating revenues for the second quarter 2002 increased 31% to Euros 49.5 million 2002 compared to same period in 2001. This increase is due to better productivity of the vessels and to a high level of pre-funding of the multi-clients programs. Meanwhile, the CGG Mistral was out of operation during the period, undergoing a major shipyard upgrade to a ten streamers capability.

Multi-client data after sales remained at a satisfactory level. As of June 30th 2002, the net book value of the library was Euros 106.0 million compared to 91M euros at the end of 200   . Backlog covers full fleet utilization throughout 2002.

     Processing & Reservoir SBU.   Operating revenues for the quarter increased 6% to Euros 28.3 million, compared to the same period in 2001. This increase is primarily due to improving volumes of high technology processing services.

     Gross operating revenues for our Products segment for the second quarter of 2002 decreased 2% to Euros 81.4 million compared to the same period in 2001. Excluding intra-group sales, net revenues decreased 30% to Euros 53.2 million compared to the same period in 2001. A decrease in demand for land products from international contractors was essentially offset by increased sales of marine products with the first delivery of the Solid Seal. The Solid Seal product line is based on the technology of the 408 system.

The backlog as of September 1^st 2002, stands at Euros 310 million, corresponding to a significant increase for the Geophysical Services, now above the pre-crisis high levels of 1997/1998.

For the first half of the year 2002, the EBITDA of Euros 95 million increased 23% compared to the first half of the year 2001 and represents 28% of the revenues.

Chairman and CEO Robert Brunck stated:

“These financial results are in line with our expectations. Our Geophysical Services have returned to profitability and Sercel, despite a more difficult market, maintains strong performance. The events at the end of last year, combined with the recent turmoil in the financial markets, have clearly negatively impacted our environment. As a result, our market in 2002 will most likely finish below our expectations. We remain nevertheless extremely confident about the growth potential of the seismic activity. Our first half, driven by a strong focus on internal performance and delivery of new technologies sets us on the right course to reach our year end objectives.”
