Engagement 2 Survey

4,000 km2 of ultralong-offset, enhanced template-matching FWI OBN data in the US Gulf of Mexico

Illuminate the subsurface in deepwater US Gulf of Mexico

WesternGeco, in partnership with TGS, is announcing a new 4,000-km2 ultralong-offset, enhanced template-matching full-waveform inversion (ETM FWI) ocean bottom node (OBN) project in the US Gulf of Mexico. This new project extends the footprint of ultralong-offset data into the south of Green Canyon and is complementary to the successful Engagement 1 program acquired in 2020.

Acquisition will be completed in Q1 2022. WesternGeco will use ETM FWI technology on ultralong offsets to provide velocity model updates. Fast-track ETM FWI RTM data will be available in late Q2 2022, and final RTM products will be delivered to licensees in Q4 2022.

Optimize well design, placement, and near-field exploration opportunities

The Engagement 2 ultralong-offset sparse OBN survey covers one of the most prolific portions of the subsalt Miocene play, including the Caesar-Tonga, Tahiti, and Stampede discoveries. Improved imaging due to ETM FWI updates to the velocity model will enable more effective well design and placement during field development activities, as well as aid in the identification and evaluation of potential near-field exploration opportunities.

Multiple untested structures at Pliocene, Miocene, and Wilcox levels in the western part of the survey, along with numerous unleased blocks, highlight the remaining exploration potential of this part of Green Canyon. Improved definition of complex salt bodies and refinement of the deep velocity structure through ETM FWI updates in this area are critical in maturing and derisking these remaining opportunities.
