Mexico’s National Hydrocarbons Commission (CNH) has authorized the acquisition of multibeam, coring, and geochemical analysis data over a 600,000 sq km area in Mexican waters. TGS-NOPEC Geophysical Co. (TGS) will conduct the work.

Mexico’s National Hydrocarbons Commission (CNH) has authorized the acquisition of multibeam, coring, and geochemical analysis data over a 600,000 sq km area in Mexican waters. TGS-NOPEC Geophysical Co. (TGS) will conduct the work.

The project will cover the entire deepwater area of the offshore sector of Mexico, including producing trends such as the Perdido Fold Belt and Campeche Bay.

This project will be conducted in conjunction with the 186,000-km TGS Gigante seismic survey, which is currently 12% complete.

The multibeam data will be acquired by Fugro using vessels equipped with the latest generation of multibeam sonar equipment. Multibeam bathymetry and backscatter data will be used to identify possible oil and gas seep targets for sediment sampling. Over one thousand navigated piston cores will be collected by TDI Brooks International and detailed geochemical analysis will be performed.

“It is a complementary addition to our Gigante regional 2D seismic program that is currently being acquired,” said Katja Akentieva, TGS senior vice-president, Western Hemisphere.

TGS will start acquisition of multibeam and coring data in this year’s third quarter, with expected completion in early fourth-quarter 2016.

This survey is supported by industry funding.
