TGS completes Gigante seismic survey offshore Mexico

Offshore staff

HOUSTONTGS has completed acquisition of its 186,000-km (115,575-mi) Gigante seismic survey offshore Mexico

Acquisition began in June 2015 with five seismic vessels contracted to acquire a dense, modern, long offset regional 2D seismic grid.

Processing of the Gigante survey is ongoing with fasttrack pre-stack time data and preliminary pre-stack depth migration products available in advance of the scheduled licensing rounds. 

Combined with TGS’ multi-beam, coring, and geochemical analysis this data is allowing geoscientists to evaluate the whole basin at a detailed level for the first time.

The company expects to complete the Gigante multi-beam bathymetry coverage in early October and the seafloor coring in December.

CEO Kristian Johansen said: “This is a significant milestone for TGS, representing the culmination of many years of planning, preparation, and operational excellence from our team. Gigante is the single largest 2D seismic survey ever acquired by TGS and we are delighted by our clients’ response to the data quality and complementary products.”
