Total Underwrites Q-Marine Survey in Deepwater Gulf

WesternGeco announced Thursday that Total E&P is underwriting a major portion of the first exploration multiclient wide-azimuth towed-streamer survey in the Gulf of Mexico. The “E-Octopus” project covers 475 Outer Continental Shelf blocks in the central Gulf of Mexico, about 125 miles offshore Louisiana in water depths of 4,400 ft.

To enhance the subsalt image, WesternGeco is employing the Q-Marine single-sensor marine seismic system with proprietary processing workflows and wavefield extrapolation migration (WEM).

“The acquisition of this extensive wide-azimuth survey will offer an enhanced ability to optimize well placement and reduce drilling risk, and will enable the comparison of geological analogues to assist in identifying potentially significant oil and gas reserves,” said Joe Varisco, WesternGeco region manager, North America. “The combination of WesternGeco Q-Technology and industry-leading expertise in wide-azimuth design, acquisition and processing is creating a step change in subsalt imaging.”

Seismic data acquisition commenced in mid-July 2006. Since then, over 200 blocks of wide-azimuth data have been acquired and are currently being processed. Completion of the survey is expected in April 2007. Fast-track WEM products will be available for interpretation in advance of the October 2007 Gulf of Mexico lease sale. Q-Marine is one of the WesternGeco proprietary suites of advanced Q technologies for enhanced reservoir location, description and management.
