Viridien strengthens seismic coverage over 134 US Gulf Outer Continental Shelf

Viridien has taken delivery of seismic field data acquired under the Momentum survey in the US Gulf of Mexico. 

It will be assimilated into the company’s Laconia sparse ocean-bottom node (OBN) program, Viridien reported Sept. 2.

Viridien expects the data to expand the OBN footprint by about 3,343 sq km over 143 Outer Continental Shelf blocks.

It will be integrated with the Laconia phases I and II datasets to improve subsalt imaging in the northern Garden Banks protraction area.

The new data was acquired using Sercel’s Tuned Pulse Source, which is designed to provide deeper diving-wave penetration, and Viridien’s elastic full-waveform inversion (E-FWI). The company expects positive results in terms of resolving complex salt geometries and deformed shale, which should lead to identification of new exploration prospects in the Paleogene trend.

Joe Zhou, Viridien's senior vice president of Americas, Earth Data, said, “It reinforces our commitment to cutting-edge Earth data solutions and advances our ability to illuminate complex Paleogene geology as Gulf exploration evolves.”
