TGS reaches halfway mark on Gigante seismic survey offshore Mexico

Offshore staff

ASKER, Norway TGS has acquired 93,000 km (57,787 mi), or 50%, of the 186,000-km (115,575-mi) 2D seismic project, Gigante

Gigante covers the entire offshore sector of Mexico and ties into the company’s regional 2D seismic grid covering the US Gulf of Mexico

Interpretation of preliminary data has identified a number of prospective play fairways within a variety of structural provinces. Delivery of fasttrack products is ongoing with more than 57,000 km (35,418 mi) presently available including areas covering the proposed bid rounds in the Campeche, Perdido, and Mexican Ridges regions.

Acquisition of the Gigante multibeam data is 12% complete with preliminary results available. The resulting detailed seafloor bathymetry provides valuable information on the structural overprint of underlying geology and can identify seafloor hydrocarbon seeps. This is used to direct TGS’ seafloor coring operations which commenced in January. 

The piston core samples will be analyzed to validate active petroleum systems and will be combined with the company’s other geoscience data as part of a comprehensive framework interpretation of the region. 

The surveys are supported by industry funding.
