West Abadi MC3D 3D GeoStreamer (In Processing)

In partnership with MIGAS, PGS acquired 5th Indonesia MultiClient survey campaign in West Abadi

The main reservoir target is the clastic Jurassic Plover Formation pervasive throughout the shelf area and successfully targeted in the surrounding fields. Imaging the deeper Triassic and even Permian section is also one of the primary objectives where the source kitchen is thought to be confined.
The survey is located immediately adjacent to the 14Tcf Abadi gas field. Prolific Mesozoic petroleum system of the north-west Australian shelf has been encountered successfully throughout the region, this survey represents an excellent opportunity to investigate the under-explored shelf-edge area.
Dual-sensor GeoStreamer eliminates the receiver ghost to deliver broadband seismic data rich in low and high frequencies. This approach preserves the prestack integrity of the data which is an essential requirement for prestack analysis for QI studies.
