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 provides new insight into the prospectivity of this frontier area and helps to better understands the uncertainties related to the identification and location of hydrocarbons.
GeoStreamer dual-sensor technology provides the broadest possible seismic bandwidth without compromise to the pre-stack data quality. The unique fidelity of GeoStreamer data enables resolving the complex overburden with great detail and helps producing clearer images of deeper reservoir structures.
