TGS Reaches 25% Acquisition Progress Mark on Gigante Seismic Program, Commences Gigante Multibeam in Mexico

HOUSTON, TX--(Marketwired - Oct 19, 2015) - TGS announced that it has acquired 46,500 kilometers (25%) of the 186,000 km 2D seismic project, Gigante. The survey is being acquired with four Seabird vessels and the fifth vessel, m/v Aquila, will join the survey in early November. Gigante covers the entire deep water area of the offshore sector of Mexico and ties into TGS seismic data acquired in the US Gulf of Mexico. Completion of the survey is expected in the second quarter of 2016. Delivery of the fast track products began in September this year.

TGS has received the environmental impact resolution from the Mexican Authorities for its multibeam survey and will shortly commence acquisition in Mexico. This survey ties into the recently completed multibeam program in the US Gulf of Mexico. Completion of the Gigante multibeam project is expected in the fourth quarter of 2016. Maps for both surveys can be found here.

"TGS' unique and comprehensive geoscience package will be an essential tool for E&P companies in their drive for hydrocarbon exploration and development success in offshore Mexico" -- comments Katja Akentieva, Sr. Vice President, Western Hemisphere, TGS.
