SLB, in partnership with TGS, has commenced acquisition of a new 161 Outer Continental Shelf (OCS) block, ultra-low frequency, ultra-long offset, ocean bottom node (OBN) project in the U.S. Offshore.

Data processing and imaging is being performed by SLB. Building on the success of Engagement 7 and 8, the survey targets geologically complex areas of the outboard Wilcox trend in Walker Ridge, expanding our OBN footprint to more than 46,000 km². Powered by advanced elastic full waveform inversion (EFWI) workflows, Engagement 9 will deliver a step change in subsurface imaging, enabling improved resolution, accuracy, and exploration risk reduction. Fast-track data will be available in Q3 2026, with final products in Q3 2027.

Engagement 8

SLB, in collaboration with E&P operators in Offshore U.S., has launched its groundbreaking Engagement 8 program. This initiative integrates decades of research and development into our most advanced ocean bottom node (OBN) acquisition yet.

Building on our industry-leading OBN portfolio—which now boasts contiguous coverage exceeding 1,430 Outer Continental Shelf (OCS) blocks (33,300 km2)—we're excited to announce Engagement 8, the largest survey of its kind, covering more than 400 OCS blocks.

Enabled by our OBN development program, this milestone project leverages our proprietary technology portfolio, including next-generation acquisition design geometries and advanced source configurations—to drive the most sophisticated elastic full waveform inversion (FWI) algorithms from SLB.

Together, these innovations unlock an unprecedented leap in subsurface resolution, fueled by ultra-long offset OBN data. Engagement 8 will deliver the clarity and confidence operators need to accelerate both exploration and development, faster and with greater certainty than ever before.
