CGG Completes Airborne Survey of Eagle Ford Shale

New High-Resolution Magnetic Multi-Client Survey Supports Texas Shale Play Exploration and Development

Paris, France – November 26, 2013

CGG announced today that it has successfully completed a multi-client high-resolution airborne magnetic gradiometer survey in the Eagle Ford shale play, Texas, USA. Deliverables from the survey will be available by the end of 2013.

This magnetic gradiometer survey, performed by CGG’s Airborne group, includes over 12,000 line miles of profile and covers DeWitt, Dimmit, Gonzales, Karnes, La Salle, Lavaca, Live Oak, McMullen and Webb counties in South Texas. It is also adjacent to several other magnetic datasets available in CGG’s worldwide multi-client gravity & magnetic (GravMag) library.

The magnetic data will assist shale exploration and development companies by detecting changes in magnetite content in the sedimentary section and hence allowing the mapping of basement and sedimentary anomalies, faults and structures. The data will also be useful for Measurement While Drilling (MWD) geosteering applications for development wells utilizing CGG’s GravMag Solutions’ MagCUBETM technology where the local magnetic reference field is computed from the aeromagnetic data and utilized in real time by drilling engineers to improve wellbore placement accuracy.

Benoît Ribadeau-Dumas, Senior Executive Vice President of CGG’s Acquisition Division, said: "The addition of high-resolution airborne magnetic gradiometer data in the Eagle Ford shale play underlines CGG’s strategy to offer the industry the very latest technology to support growing demand for shale exploration, production and development. We are currently preparing to undertake similar projects in other shale play areas as we regard the US domestic shale play as an important region for the expansion of our multi-client data offering."
