HOUSTON – Fugro has deployed the multi-purpose survey vessel Fugro Gauss to join the Fugro Brasilis offshore Mexico, to help complete what it says is the world’s largest seep-hunting survey.
Both vessels are using hull-mounted multi-beam echosounders (12 kHz on Fugro Gauss and 30 kHz on Fugro Brasilis) and sub-bottom profiler systems to map an area of about 625,000 sq km (241,313 sq mi) in the deepwaters of Mexico.
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 has a dedicated center of excellence in Houston for seep-hunting,” explained Jim Gharib, Fugro’s Global Product Line Manager for Seep Studies. “Our recent successes include nine seep data collection and geochemical analysis projects in the Gulf of Mexico, the Caribbean, and Southeast Asia.”
The survey is being conducted for TGS as part of its industry-funded multi-client Gigante survey which also includes a regional 2D seismic survey of approximately 186,000 km (115,575 mi), gravity and magnetic data, and a regional seismic structural interpretation.
TGS aims for this project to be the most comprehensive and modern offshore Mexico dataset 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 license rounds.
