First Break - Volume 15, Issue 5, 1997

CGG has come up with a novel solution to obtaining detailed ocean bottom surveys in using dynamically positioned vessels to shoot and record seismic in tandem with seabed nodes positioned by ROVs.

Fugro is a name we are going to hear a lot more of. First Break tells how the Fugro Group has spent the last 5 years acquiring a specialist business in survey and positioning.

Featured here are just some of the companies active in the geoscience area of the exploration industry including products on display at the 59th EAGE Conference and Technical Exhibition, Geneva, Switzerland, 26-30 May 1997, based on information supplied by the companies

The CD-ROM (Compact Disc - Read Only Memory) technology, introduced to the general market by Philips and Sony in 1984, became more widely available in the early 1990s. However, only in 1994 was there a breakthrough in the use of CD-ROM technology in both professional and consumer markets. The number of different CD-ROM titles totalled 1500 in 1991. It now well exceeds 10,000 or maybe even 20,000, covering a wide range of fields including databases, educational and scientific applications, and games.

Time-lapse crosshole seismic surveys have been conducted over a naturally fractured reservoir to demonstrate the feasibility of obtaining high-resolution seismic images to monitor changing fluid saturation within the reservoir. The experiment was perforrned at the Chalmers Hot Dry Rock (HDR) geothermal research site in Fjällbacka, Sweden, across a fractured reservoir. in crystalline rock at around 450 m depth. Although the survey technique being demonstrated is intended to be applied to oil reservoirs, the Fjällbacka site was selected as the geothermal reservoir there is analogous to a naturally fractured oilfield reservoir but is far more readily accessible for experimental work.
