PetroFrontier Corp., Calgary, reported encouraging oil and gas indications at three horizontal wells in Australia’s southern Georgina basin as the company launched a share offering to fund the rest of its 2012 exploration program in the basin with Statoil Australia Oil & Gas AS (OGJ Online, June 20, 2012).
PetroFrontier’s third horizontal well, Owen-3H in Northern Territory EP 104, reached total depth of 2,153 m measured depth including a 966-m horizontal section. The company set a multistage open hole completion string in preparation for a completion attempt targeting the Middle Cambrian Lower Arthur Creek “hot shale” and Thortonia carbonate.
While drilling the Owen-3H lateral, the company observed numerous positive hydrocarbon indicators including oil staining, milky yellow fluorescing cut, strong gas recordings of C1 to C5, petroliferous odor, and oil in the mud at the shaker.
As previously reported, PetroFrontier retrieved 32.5 m of core from the Owen-3 inclined wellbore that bled oil upon recovery and had extensive fluorescence throughout. Wireline logs indicated more than 25 m true vertical thickness of hydrocarbon-bearing formations.
PetroFrontier’s three wells are MacIntyre-2H, Baldwin 2H, and Owen-3H. Completion is under way at MacIntyre-2H in EP 127 but is not finished.
