MCS Guyana Stabroek 2D GeoStreamer®

PGS offers 11,163 km of long-offset GeoStreamer® MC2D marine seismic in the Guyana Basin.
Provides a modern, comprehensive seismic address of the proximal Guyana Basin.
Potential across the basin is believed to exist in stratigraphic targets within Tertiary and Cretaceous turbidite sandstones basin floor fan systems analogous to those proven in Angola and Sierra Leone. Cenomanian-Turonian deep marine shales of the Canje Formation are considered the primary source.
