Prospect Description: The Star Finch Prospect is a reverse faulted anticlinal structure formed by mid-Miocene compression. Potential hydrocarbons in the Star Finch structure are interpreted to have migrated up out of the Devonian sediments by faulting and fracturing during this compression. The main objective in the Star Finch Prospect is the Birdrong Sandstone. The nearby Bibbawarra Bore encountered approximately 15 metres of Birdrong Sandstone sealed by 27 metres of Muderong Shale. The prospect covers a large area of 3,000 hectares and potential recoverable reserves are estimated to be of the order of 50 billion cubic feet of gas or 25 million barrels of oil assuming a 5 metre oil leg. The Star Finch Prospect demonstrates bright seismic anomalies over the mapped closure. Bright anomalies have been a successful indication in many cases for natural gas entrapment in the Carnarvon Basin. 18.
