West Papua - Indonesia - 2007

South Kamrau 2D

The survey area covers the western edge of the Arafura Platform and extends into the Aru Basin
Website Map for Survey South Kamrau MC2D
The South Kamrau area is considered a frontier exploration area with only 2 wells drilled offshore in the 1970’s.
The area lies in a very complex geologic setting where the Australian plate subducts under the Asian plate. Complex overthrusts can be seen overriding the Australian plate. The main play is in the large anticlines/fault bounded closures containing both Miocene carbonate and clastics.
The 1 612 line km acquired with a 6 km streamer was merged and matched to the GeoStreamer data before being incorporated into the Abadi-Aru-Arafura MegaProject.
