Cambodia 2D

Dataset covering the unexplored petroleum systems offshore Cambodia
Website Map for Survey Cambodia MC2D
The survey provides a unique opportunity to gain insight into one of the few remaining unexplored areas in the region surrounded by proven petroleum systems.
The main plays are channels and stacked channel sandstones lying adjacent to faults in the Miocene and Oligocene sequences. Source rocks are expected to exist at several stratigraphic levels, however the best source rock for the area is the late Oligocene – earliest Miocene lacustrine mudstones.
The survey, consisting of 2 423 line km, was acquired using a 6 km streamer.
