Sercel 508XT land acquisition system passes 1 million VP milestone in Saudi Arabia

Paris, France – February 23, 2016

CGG announced today the successful large-scale deployment of Sercel's new-generation 508XT land seismic acquisition system on a high-productivity super crew conducting a seismic survey in Saudi Arabia. The system is currently deployed on a crew operated by ARGAS, CGG's joint venture with TAQA, and achieved the milestone of one million VPs (Vibrated Points) in January 2016. Since its launch in 2013, the 508XT has been successfully fieldproven in the toughest 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 consistently provided outstanding vibroseis production rates while recording highly accurate seismic data. The crew is currently operating with 12 fleets of two Sercel Nomad 65 Neo allterrain 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 a 150 km² active spread.

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

Pascal Rouiller, Sercel CEO, said: "This new performance milestone underlines Sercel's success at designing the most advanced equipment solutions to meet the needs of highproductivity seismic acquisition programs. We believe that our 508XT's unique X-Tech recording capabilities represent a breakthrough for all our customers, whether they wish to maximize crew productivity or increase their operating flexibility."

Saad S. Al-Akeel, ARGAS CEO, said: "In addition to the direct benefits of its X-Tech architecture, the 508XT's low power consumption combined with a requirement for less field units and batteries brings a significant weight saving, directly impacting our crew productivity and minimizing our HSE exposure. In addition, the 508XT equipment is easy to manage and its reliability so far has been excellent."
