Beantree Prospect is an anticlinal play in the Patchawarra Trough of the Cooper Basin. Current seismic coverage and quality are adequate to place the existence of closure beyond reasonable doubt. Up to 500 feet of vertical closure occurs within a 1620 feet thick sequence of Permian sediments. The prospect contains 1370 feet of prospective section in the Toolachee, Epsilon and Patchawarra Formations. A total Net Effective Pay of 180 feet is predicted. The nearest well to Beantree in the Patchawarra Trough, Coonatie 1, a gas well, is 35 km away. This large separation reduces the confidence level with which stratigraphic predictions can be made for Beantree. However, both Coonatie and Beantree Prospects are close to the axis of thickest sediments in the Patchawarra Trough, and thus should each have experienced similar structural and depositional histories. Seismic sections show evidence of significant change of character and continuity of reflections along a north-south line which lies between Coonatie 1 and the proposed Beantree 1. Major changes of lithologic facies may occur across this boundary. The proposed well will therefore provide stratigraphic information in an area remote from other drilling. The anticipated total depth of Beantree 1 is 12,000 feet, in pre-Permian sediments. Assuming a trap existence risk of 1, the maximum gas-in-place reserves are estimated to be 180 BCF. This well is proposed as part of the 1978 Independent Exploration Programme to be carried out on behalf of PASA. Delhi will be the operator. Ownership of any petroleum discovered will remain with the partners to the Patchawarra East Farmout agreement.
