ANG Onshore Lower Congo 2D

Onshore seismic data, brokered in co-operation with Sonangol
Website Map for Survey ONSHORE LOWER CONGO ANGOLA
PGS is brokering over 1600 km of newly acquired 2D seismic data to investigate the hydrocarbon potential of the Lower Congo Basins.
The basin is considered to be only lightly explored. A total number of 95 wells have been drilled since the early 1915: 9 oil fields and two discoveries have been found.
The 2D lines provide better imaging of both post-salt and pre-salt and have been processed using a robust Pre-Stack Time Migration processing workflow.
