Central Petroleum Limited
(ASX:CTP) (“Central” or the “Company”) has pleasure in releasing a Technical Note by Greg Ambrose, Manager Geology, and John Heugh, Managing Director, “Fractured Basement Hydrocarbon Plays and “Buried Hill” Plays in Central Australia” (CTP Technical Note 11.07.15). The report concludes, inter alia, that :
- Hydrocarbon production from fractured crystalline basement terranes occur on a global scale with production in 30 countries; Vietnam, Russia and Argentina are noteable examples, particularly the Cu Long Basin White Tiger and Bach Ho fields, with combined production reaching in excess of 40,000 BOPD.
- These plays are completely unexplored in Central Australia despite favourable geological criteria in several basins and numerous examples from many basins around the globe.
- CTP’s holdings in the Amadeus, Georgina and Pedirka basins include specific areas where structurally deformed crystalline basement terranes have potential to reservoir hydrocarbons generated from known source sequences in close vertical proximity to basement.
- The Mirrica Prospect in the Southern Georgina Basin is a large fault dependent closure mapped at basement and higher levels against the Toomba Fault updip of the Toko Syncline. The UGIIP (Undiscovered Gas Initially In Place) at Middle Cambrian levels may exceed 4 TCFG if the structure is filled to spill. (ie “high” estimate). Mirrica-1 intersected partly weathered granitic basement within closure but little is known of this secondary target. Higher in the section, brittle carbonates of the Thorntonia Limestone are blanketed by regionally developed shales of the lower Arthur Creek Formation (source and seal) and these constitute a regional fracture play.
