Dutch firm Fugro has deployed its multi-purpose offshore survey vessel Fugro Gauss (pictured) to join the Fugro Brasilis in Mexico to assist in the completion of the world's largest seep-hunting survey for Norwegian seismic survey company TGS.
The survey is being conducted for TGS as part of its industry-funded, multiclient Gigante survey, which also includes a regional 2D seismic survey of about 186,000km, gravity and magnetic data and a regional seismic structural interpretation, Fugro said in a press release.
Both Fugro vessels are using hull-mounted multibeam echosounders and sub-bottom profiler systems to map an area of approximately 625,000km2 in Mexico's deep waters.
"The data acquired will assist in identifying sites where deep hydrocarbon-rich fluids are escaping to the seafloor and will be used to target hundreds of sites for coring and geochemical analysis," Fugro said.
TGS said in May it had completed roughly 75%, or 141,000km, of the planned 186,000km Gigante 2D seismic project.
TGS aims for this project to be the most comprehensive and modern offshore Mexico dataset, and which ties into its existing US Gulf of Mexico regional 2D grid.
"The survey is designed to assist exploration and production companies in their evaluation of prospectivity offshore Mexico during forthcoming licence rounds," Fugro said."Interest in this area is high following the denationalisation of Mexico's oil and gas market after seven decades of government control."
Mexico is due to hold its first-ever deepwater auction on December 5.
