Precambrian frontier opportunity in Australia's Beetaloo sub-basin
- Pacific Oil Gas Pty. Ltd., Box Hill (Australia)
A previously unexplored sub-basin of the Precambrian McArthur basin in northern Australia is developing into an exciting new petroleum province. Exploration by Pacific Oil Gas Pty. Ltd. the past 7 years has indicated that vast amounts of hydrocarbon have been generated from thick, highly organic rich shales present throughout the Beetaloo sub-basin. Several potential sandstone reservoirs are conveniently situated to be charged from the source units. Pacific has recovered oil and gas from these sandstones in several exploration wells demonstrating that maturation, migration, and preservation of hydrocarbons have been effective within the sub-basin. With only a few poorly defined targets drilled to date, more exploration is required to assess fully the hydrocarbon potential of the Beetaloo sub-basin. In addition to exploration for conventionally trapped oil and gas, Pacific has also been evaluating innovative methods to recover the immense resource of unmigrated live oil present within the source units. The paper discusses regional geology, Pacific's exploration, source and maturity, the reservoir, structure, and the potential for this area.
