OSLO, Norway – TGS has started acquisition of the Espirito Santo multi-client 3D seismic survey offshore Brazil.

The multi-client survey will cover 2,694 sq km (1,040 sq mi) over the basin, broadening 3D coverage in the region. It is being acquired in a dual-azimuth acquisition format.

TGS will process the data using Dynamic Matching Full Wave Inversion (DM-FWI), a technology that employs seismic reflection and refraction information to automatically update the velocity model.

According to the company, this results in geologically coherent velocity models, improved subsurface analysis and reduced uncertainty.

Imaging in depth is clearer and more geologically consistent, while overcoming many of the limitations of standard FWI, TGS added.
