Second CGG BroadSeis multi-client survey in Norway offers new seismic footprint in Barents Sea

Paris, France – 9 October, 2013

CGG announced today that it has successfully completed a second BroadSeisTM multi-client survey offshore Norway. The survey covers a 2,300 km² area in the Barents Sea. Fast-track processing deliverables will be available by the end of 2013 and final processing products by August 2014.

This second BroadSeis 3D survey is located in the southeastern part of the Barents Sea adjacent to the recent eastward extension of Norwegian territory as a result of the border agreement between Norway and Russia. New data is required to assess the petroleum potential in this region.

The Barents Sea BroadSeis survey follows on from CGG's recent first BroadSeis multi-client survey offshore Norway which targeted the Halten Terrace. The industry has shown strong interest in this new multi-client data acquired with CGG's broadband technology and initial results just released show a significant improvement in the imaging of deeper targets.

Jean-Georges Malcor, CEO, CGG, said: "CGG regards Norway as an important region for the expansion of its multi-client activities and is working on several new projects including the Barents Sea survey. Our geologists are optimistic about this region's oil potential and we consider it to be a strong candidate for inclusion in Norway's 23rd licensing round set to take place in the second half of 2014. Our recently expanded team of multi-client experts in Norway drew on their extensive knowledge of the Barents Sea region to design this BroadSeis survey and we are convinced that the resulting images will enhance the industry's geological understanding of this promising region."
