Areas ER96-A, B, C and D located in the Eromanga Basin, South Australia, are available for Petroleum Exploration Licence applications until 27/9/96 by invitation via this promotional brochure, prepared for distribution to industry both locally and overseas. The blocks lie adjacent to PELs 5 and 6 which covers the Cooper Basin - Australia's largest onshore oil and gas province. They also lie on a large structural complex, the Birdsville Track Ridge, which separates the Mesozoic Poolowanna Trough depocentre from the Permian to Mesozoic Cooper Basin depocentre. The geology of the region is known from relatively limited seismic and petroleum drillholes. Fair to excellent quality sandstone reservoirs are sealed by siltstone and shale units - these reservoir/seal units are proven producers in the nearby Cooper Basin region. In addition, many prospects and leads have been identified by former explorers in the region and by MESA. Furthermore, new geochemical data from the Poolowanna Trough and Birdsville Track Ridge area indicate that organic-rich shales in the Eromanga Basin are oil-prone and are at the peak of maturity for oil generation in the Poolowanna Trough, thus enhancing the hydrocarbon potential of the blocks on offer.
