CGG deploys land seismic system in Saudi Arabia

CGG, a global geoscience company. has deployed Sercel's new-generation 508XT land seismic acquisition system for a large-scale seismic survey in Saudi Arabia.

The system is currently deployed with a crew operated by ARGAS, CGG's joint venture with TAQA. In January, the system achieved the milestone of one million vibrated points (VPs). Since its launch in 2013, the 508XT system has been utilized in tough conditions in various environments, such as Arctic, farmland, and desert areas.

The ARGAS land crew has been working in Saudi Arabia since October 2015, where it has provided vibroseis production rates while recording seismic data. The crew is currently operating with 12 fleets of two Sercel Nomad 65 Neo all-terrain broadband vibrators using the DS4 (Distance-Separated Simultaneous Slip-Sweep) vibroseis source method. For data recording, the crew is employing nearly 40,000 channels and 360,000 sensors in an active 150-square-kilometer spread.

Its deployment on this high-channel-count survey enables the Sercel 508XT system to demonstrate the full benefits of its cross-technology (X-Tech) architecture, which combines cabled and wireless system characteristics to optimize crew productivity and reduce operational downtime.
