ANG Onshore Kwanza 2D

Onshore seismic data, brokered in co-operation with Sonangol
Website Map for Survey ONSHORE KWANZA ANGOLA
PGS is brokering over 2 500 km of newly acquired 2D seismic data to highlight the proven hydrocarbon potential of the Inner Kwanza Basin.
The basin is considered to be only lightly explored. A total number of 133 wells have been drilled since the early 1950s: 11 oil fields and two small gas fields have already been discovered.
The 2D lines provide better imaging of both post-salt and pre-salt and have been processed using robust Pre-Stack Time and Depth Migration processing workflows.
