Abstract

ATP 636 is a lightly explored permit on the eastern margin of the Cooper-Eromanga Basin, more than 60km northeast of the Jackson Oil Field in South-West Queensland. Prior to award of the permit, heritage seismic data was very limited and no wells had been drilled within the permit area.

Low-fold 3D seismic was acquired (the “Gumbo 3D”) in place of a more conventional program of 2D seismic followed by 3D seismic. The location of the low-fold 3D seismic survey within the permit was determined using play-based exploration principles.

The seismic data quality compares favourably with full-fold 3D seismic from a structural perspective and provides good imaging of faults and key stratigraphic units. The result is a robust interpretation and a well-defined inventory of prospects and leads.
