Congo Basin - Congo - 2015

CGO Marine XX 3D GeoStreamer®

High-quality enhancement to Congo MegaSurvey dataset

This conventional dataset includes 2918 sq. km of high-quality 3D seismic data.

The data targets the proven Miocene channel and Sendji carbonate plays, as well as prospectivity in the under-explored presalt section.

Simultaneous long offset 3D GeoStreamer data has provided denser sampling and higher fold. This has improved model building and imaging of both the postsalt channels and plays, and the presalt section.
