TGS completes Gigante seismic survey off Mexico

TGS, a provider of multi-client geoscience data to oil and gas companies, has completed the acquisition of its 186,000 kilometers Gigante seismic survey offshore Mexico. 

TGS said on Tuesday that the acquisition of this survey began in June 2015 with five seismic vessels contracted to acquire a dense, modern, long offset regional 2D seismic grid.

According to the company, Gigante covers the entire offshore sector of Mexico and ties into the company’s regional 2D seismic grid covering the entire U.S. Gulf of Mexico.

Processing of the Gigante survey is ongoing with fast track PSTM and preliminary PSDM products available in advance of the scheduled licensing rounds.

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

The company said that it expects to complete the Gigante multibeam bathymetry coverage in early October and the seafloor coring in December.

Kristian Johansen, CEO of TGS, 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.”
