PGS and Partners Complete Abadi-Arafura-Aru Cross-Border Seismic Survey

PGS, in conjunction with Spec Partners, Horizon, and SKK Migas announced Thursday the completion of the Abadi-Arafura-Aru (AAA) MegaProject off eastern Indonesia and northern Australia.

This unique cross-border seismic study, which extends from Eastern Indonesia through the northern margin of Australia, is based on the integration of several seismic surveys and full tectono-stratigraphic interpretation of 16,466 line miles (26,500 line kilometers) of modern long offset, MultiClient 2D seismic data, largely acquired using PGS GeoStreamer technology.

The survey ties the main structural elements from East Timor and the Petrel Basin in the west, to the Seram Trough and Arafura Basin in the east, and provides a much improved understanding of regional stratigraphy and basin development.

Large parts of the area remain underexplored and poorly understood. The cross-border AAA MegaProject helps fill that knowledge gap. It reveals the petroleum system along the southern and southeastern margin of Indonesia by tying key wells and discoveries along the northern margin of Australia, which is more mature in terms of exploration. 

The project has been the basis for detailed geological analyses by Horizon. These include tectonic and palinspastic reconstructions from Permian to present, geochemical modeling of all potential source rocks in the area, well failure analyses, play fairway mapping, and prospectivity assessment.

The AAA MegaProject is a comprehensive regional seismic and prospectivity package which will help oil companies gain a better understanding of the petroleum systems in this vast, underexplored area, helping them to identify exploration “sweet spots” with increased confidence.
