  Revolution XII/XIII

  • TGS and Schlumberger jointly acquired the Dual Coil Shooting* multivessel full-azimuth acquisition Revolution XII and XIII surveys in the U.S. Gulf of Mexico. The surveys cover approximately 7,150 km² (306 blocks) in the Green Canyon, Atwater Valley and Ewing Bank protraction areas of the Central Gulf of Mexico and recorded offsets of more than 14 km imaging below the salt in the deepwater Gulf of Mexico.
  • Revolution Xll and XIII surveys was acquired using the Schlumberger WesternGeco Q-Marine* point-receiver marine seismic system combined with the proprietary multivessel, Dual Coil Shooting acquisition technique, that provided broadband, long-offset, full-azimuth data. This combination of leading-edge technology and technique has improved illumination and imaging of the sub-salt and other complex geologic features in this highly active region.

  Orion 3D

  • Orion is TGS’ 9,000 meter streamer offset multi-client 3D survey located in the Gulf of Mexico that began acquisition in early 2008. 
    Orion 3D covers approximately 175 OCS blocks (4,100 square kilometers) in the Lloyd Ridge OCS area. The exploration potential for this area includes seismic attribute plays as well as deeper structural opportunities.
  • The Orion 3D program area is located in close proximity to the Independence Hub production facility operated by several independent oil companies. This large facility produces gas from a number of discoveries that have been made in the area including Spiderman, San Jacinto, Atlas Northwest, Atlas, Mondo Northwest and Cheyenne.
  • Orion 3D survey was acquired utilizing the Fugro GeoBarents seismic vessel. The data was recorded with 9000 meter streamer offsets and was processed with both pre-stack time and pre-stack depth imaging by TGS' own Imaging Services division. In addition to the full offset migrations, partial offset stacks have been generated for evaluating Amplitude Variation with Offset (AVO).
