JUNE/JULY 2009 SA MINES & ENERGY JOURNAL 35 FEATURE carbon dioxide sequestration by re-injection to depleted reservoirs at its Ladbroke Grove processing plant. The plant is suitable because it was designed for gas with a high percentage of carbon dioxide from the Ladbroke Grove Fields in the same area as Katnook. More interestingly, perhaps, is Adelaide Energy’s plans for expansion. Now that it has a revenue stream, Mr Dorsch is turning his attention to other opportunities. Two new large petroleum exploration licences in the same area were issued by the State Government to Adelaide Energy in March. These form part of the company’s plan to further develop the potential in this potentially hydrocarbon-rich region. Two proven gas wells at Jacaranda Ridge and Limestone Ridge could produce five to seven terra-joules per day, for want of some straightfor ward, low-environmental-impact infrastructure. The Jacaranda Ridge 2 discovery well has booked recoverable reserves of 131,000 barrels of oil equivalent. Limestone Ridge has booked recoverable reserves of 71,400 barrels of oil equivalent. Dr Peter Bolt, an expert in thrust faulting, helped Adelaide Energy locate large anomalies suggesting promising potential just a short distance from the original Origin well. Studying faults, cracks, some leaking gas, some sealing – it is all part of the interesting game of exploration. Adelaide Energy is planning two new wells and pipelines to connect wells to existing systems. The two new wells would cost around $6 million and the nearly 9km of pipelines won’t give much change from $4 million. But the potential has Mr Dorsch excited. The company’s testing to date and recently analysed 3D seismic surveys give him confidence Adelaide Energy will get an excellent return on its investment ... when the company can raise additional funds. It is experiencing the same struggle for capital investment in the current economic climate as many petroleum explorers and producers. Yet Mr Dorsch is confident the potential is attractive enough that the company can proceed. • Gum Flat Iron Ore • Wilcherry Uranium • Cockabidnie Nickel Cobalt • Torrens Copper and more to come...
