PGS completes Indonesia-Australia megaproject 

OSLO, Norway -- PGS, in conjunction with Spec Partners, Horizon, and MIGAS, has completed the Abadi-Arafura-Aru (AAA) megaproject. This 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 26,500 line km 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.
