Schlumberger embarks on multiclient WAZ survey in Campeche Basin

Offshore staff

HOUSTON Schlumberger has launched a new deepwater multiclient wide-azimuth seismic survey in the Campeche basin, located in the Mexican sector of the Gulf of Mexico.

The acquisition of what the company says is the industry’s first multi-client wide-azimuth survey offshore Mexico will cover 80,000 sq km (30,000 sq mi) using two fleets of WesternGeco vessels. Included will be the company’s Amazon class-vessels, which Schlumberger says is the world’s first purpose-designed 3D seismic vessels.

A suite of wide-azimuth, long offset, and broadband seismic surveys will be used in response to the Campeche basin’s near-salt and subsalt structures, complex faulted structures, and deep-thrusted structures. In such complex geology, where illumination of the subsurface is challenging, wide-azimuth acquisition and broadband imaging technologies deliver advanced data to support identification of subtle structural and stratigraphic traps, provide better delineation of fractures, and improve reservoir characterization, Schlumberger explained.

Following completion of the seismic acquisition program in early 2016, customers will have access to images to support future appraisal campaigns in this frontier play. Additional Schlumberger multi-client projects in Mexico include reimaging of the Campeche and Perdido basins.
