Study targets area off Australia, Indonesia

Petroleum Geo-Services said an international seismic study has improved understanding of regional stratigraphy and basin development in an area offshore eastern Indonesia and northern Australia.

The project integrated several seismic surveys and full tectono-stratigraphic interpretation of 26,500 line-km of long-offset, multiclient 2D seismic data.

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.

PGS, which worked with SpecPartners, Horizon, and MIGAS, said the study “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.”

Horizon conducted geological analyses including tectonic and palinspastic reconstructions from Permian to present, geochemical modeling of all potential source rocks in the area, well-failure analysis, play fairway mapping, and prospectivity assessment.
