To enhance the subsalt image, WesternGeco will employ Q-Marine(a) technology, with proprietary processing workflows and wave extrapolation migration (WEM).
Seismic data acquisition will begin in the middle of this month and conclude as early as December utilizing a unique design co-developed by WesternGeco and Shell. A final WEM product will be available for interpretation in advance of the March 2008 lease sale.
"This project provides WesternGeco with the opportunity to set the standard for wide-azimuth design, acquisition, and processing using Q-Marine technology and breakthroughs in WAZ seismic processing," said Maurice Nessim, Vice President, North America, WesternGeco. "The multiclient product will provide value by allowing a greatly improved image of key blocks on offer in the March 2008 and subsequent lease sales, and reducing subsalt drilling risk."
Shell Exploration and WesternGeco recently collaborated on a proprietary survey in the Gulf of Mexico applying a unique WAZ survey design to illuminate the geology beneath complex salt. The success of that project has led to this new WAZ multiclient survey, an acquisition step-change required for subsalt illumination in parts of the Gulf of Mexico and other salt provinces around the world.
