    TGS halfway through Gigante seismic programme offshore Mexico

    Projects and Operations // February 3, 2016

    TGS has announced that it has acquired 93,000km (50 per cent) of the 186,000km Gigante 2D seismic project. 

    Gigante covers the entire offshore sector of Mexico and ties into TGS' regional 2D seismic grid covering the entire US Gulf of Mexico. 

    Interpretation of preliminary data has identified a number of prospective play fairways within a variety of structural provinces. Delivery of fast track products is ongoing with over 57,000km 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 per cent 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 TGS' other geoscience data as part of a comprehensive framework interpretation of the region. The surveys are supported by industry funding.
