ANG Blk 24 Reprocessed 3D

A multi-azimuth volume covering the entirety of offshore Angola Block 24
Website Map for Survey ANG_24_MC3D
PGS has a number of MultiClient 3D datasets over Block 24. These 3D datasets have been converted into a modern MultiAzimuth 3D volume; providing broader bandwidth pre-salt illumination.
Angola offshore acreage has world-class potential, with a petroleum system within the syn-rift pre-salt section. This is similar to the proven producing systems along the conjugate margin of Brazil (Campos and Santos Basins).
