Outeniqua/Bredasdorp Basin - South Africa - 2015

SA South Coast 2D GeoStreamer®

Broadband 2D dataset over South Africa's Outeniqua and Bredasdorp Basins
Website Map for Survey SAFR MC2D 2015
The survey will further de-risk this frontier area providing the insight necessary to determine the true prospectivity and observe the possible petroleum systems at work in the subsurface.
Targeting a likely deltaic system of clastic sediments and sandstone reservoirs the data will be collected in water depths ranging from 200 m - 4 000 m.
GeoStreamer data is the ghost-free broadband solution resolving structural details in the shallow and allowing greater penetration and deeper imaging.
