Conventional MultiClient 3D data offshore Nigeria
Website Map for Survey NGA_213_MC3D
This 3D seismic survey is at the heart of the highly prolific Niger Delta. Additional information is available upon request.
The data acquired is located over the licensed block OML 132 and the open block OPL 286 in an area dominated by complex delta-front tectonics.
The 3D survey lies landward of the lower compressional zone of toe thrusts, and is cut by a bifurcating elongate shale wall. Fields and discoveries such as Boi and Ogide are directly East of the survey.
