The Next Phase of Ultra-long Offset FWI Node Projects in U.S. Gulf of Mexico

Engagement

Following the highly successful Amendment Phase 1 project acquired in Mississippi Canyon in 2019, TGS, in strategic collaboration with Schlumberger, has commenced the second phase of the ultra-long offset node project in the U.S. Gulf of Mexico. The next phase, "Engagement," will extend the footprint of ultra-long data in the Northern Green Canyon protraction area.

This area is characterized by complex geology and multiple salt bodies, driving industry towards a new approach to illuminate the subsurface structures. The combination of ocean bottom node data, used to record ultra-long offsets and full waveform inversion, is expected to deliver a significant uplift to the velocity model which in turn will be used to amend the existing WAZ and Coil data in the area.

Acquisition of the project was completed in September 2020 and final data is expected in 2021. The Amendment and Engagement projects represent a new generation of survey design, with significant areas in the Gulf of Mexico and elsewhere that will benefit. The next phase, "Engagement," will extend the footprint of ultra-long data in the Northern Green Canyon protraction area.

What is Dynamic Matching FWI?

Senior Researcher Jian Mao presents the advanced Dynamic Matching Full Waveform Inversion (DM FWI) algorithm and its applications on field datasets

Dynamic Matching FWI allows for superior, geologically coherent velocity models, improved subsurface analysis and reduced uncertainty. It will enable reduced cycle times, cost reduction and significant de-risking in complex imaging areas.

Lease Sale 254 Results

The U.S. Department of the Interior’s Land and Mineral Management and Bureau of Ocean Energy Management (BOEM) held a regionwide lease sale for 78 million acres in the federal waters of the Gulf of Mexico (GoM) on March 18, 2020. Lease Sale 254 included 14,585 unleased blocks, from three to 231 miles offshore, in the Gulf’s Western, Central and Eastern planning areas in vary water depths of 9 feet up to more than 11,000 feet.
