These acquisitions are the initial phase of the Revolution X and Revolution XI surveys and will provide full-azimuth, high-density broadband data to optimize future operational decisions.
When completed, the Revolution X and Revolution XI surveys will provide more than 3,800 sq km (1,467 sq mi) and 2,940 sq km (1,135 sq mi) of 3D data respectively for suprasalt and subsalt targets, and deeper subsalt Miocene and Wilcox formations.
“The new exploration investments will enable customers to make better-informed, strategic decisions during exploration as well as field development and production phases,” said 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 company says the combination of WesternGeco Dual Coil Shooting multi-vessel full-azimuth acquisition, with proprietary ObliQ broadband acquisition and imaging technology, optimizes the recorded bandwidth of the seismic signal to enhance imaging of potential subsalt prospects.
