TGS will charter up to six seismic vessels for about three years, and the survey will cover a minimum of 150,000km and up to 300,000km in Mexico and US Atlantic waters.
Survey work is expected to begin in the first half of 2015, subject to the issuance of acquisition permits to TGS, and is estimated to value from $88m for 150,000km to $176m for 300,000km.
TGS Western Hemisphere senior vice-president Rod Starr said: "TGS is pleased to have secured customer funding and access to seismic vessels for the regional 2D activity that is targeted for 2015.
"There is a high level of oil company interest in Mexico and US Atlantic and we believe that these will be important regions for future exploration."
TGS offers multi-client geoscience data to global oil and gas exploration and production companies.
In September, TGS was selected for the initial two ocean bottom seismic surveys to be undertaken in the US Gulf of Mexico (GoM). The projects include the Calypso full azimuthal nodal (FAN) survey and the Nessie FAN survey.
The two projects form part of a multi-year collaboration agreement signed by FairfieldNodal and TGS in August to develop, plan and implement multi-client FAN seismic surveys across a substantial area within the US GoM shelf region.
