Latest technologies for survey acquisition and imaging employed

Schlumberger has announced the completion of the acquisition of approximately 2750 km2 of two new full-azimuth multiclient seismic surveys over the Garden Banks and Green Canyon areas in the Gulf of Mexico. These acquisitions are the initial phase of the Revolution X and Revolution XI surveys and will provide full-azimuth, high-density broadband data to optimise future operational decisions.

“The new exploration investments will enable customers to make better-informed, strategic decisions during exploration as well as field development and production phases,” says Maurice Nessim, president, PetroTechnical Services, Schlumberger. “These high-density broadband surveys that use our latest acquisition and imaging technologies will deliver critical information that can help reduce drilling risks and support future 4D reservoir monitoring.”

The combination of WesternGeco Dual Coil Shooting multivessel full-azimuth acquisition, with proprietary ObliQ broadband acquisition and imaging technology, optimises the recorded bandwidth of the seismic signal to enhance imaging of potential subsalt prospects.

When completed, the Revolution X and Revolution XI surveys will provide more than 3800 km2 and 2940 km2 of 3D data respectively for suprasalt and subsalt targets, and deeper subsalt Miocene and Wilcox formations.
