Copenhagen, Denmark –The second day of the annualEuropean Association of Geoscientists & Engineers Conference and Exhibition has seen additional technology announcements:

Sercel – CGGVeritas announced that Sercel has launched its latest generation Sentinel solid streamer, the RD. Compatible with Sercel’s Seal 428 and Sentinel, the Sentinel RD has a reduced diameter and a 15% weight reduction, providing reduced cable drag and increased storage capacity onboard seismic vessels. “Sentinel RD can be deployed for a wider range of layout options including denser or longer configurations to meet growing demand for high-end marine seismic techniques such as broadband, high-density and long-offset acquisition,” says Jean-Georges Malcor, CEO, CGGVeritas.

Schlumberger – Also at EAGE, Schlumberger released its IsoMetrix marine isometric seismic technology and the IsoMetrix family of products. This technology outputs isometrically sampled point-receiver data in both crossline and inline directions – capturing the returning wavefield in three dimensions to provide the most accurate images of the subsurface ever recorded, says Schlumberger. The system uses calibrated, multi-sensor MEMS technology as part of the new WesternGeco Nessie-6 point-receiver seismic streamer. The sensors measure acoustic pressure as well as vertical and crossline acceleration throughout the frequency range, and these measurements are provided as customer deliverables.

Paradigm – Cairn Energy Plc has selected Paradigm’s toolkit as its next generation 2D and 3D seismic data interpretation program. Cairn says it will use the system on the 3D survey data acquired in 2011 offshore Greenland. Paradigm says the system is designed to handle large 2D and 3D surveys with multiple well databases.
