CALGARY, Oct. 12, 2012 /PRNewswire/ - (TSXV: PFC) - PetroFrontier Corp. ("PetroFrontier") is pleased to provide an operational update regarding its current well completion operations in the Southern Georgina Basin, Northern Territory, Australia. Owen-3H A successful hydraulic stimulation was performed on the Owen-3H well over ten open-hole stages. PetroFrontier is very encouraged by the low fluid injection pressures and high injection rates evident during the stimulation. Log data and core samples have been obtained and appear positive, confirming the existence of oil in the Lower Arthur Creek and Thorntonia Carbonate Formations . PetroFrontier is now preparing to conduct an extended flow-test of the Owen-3H well prior to the wet season. PetroFrontier and its joint venture partner (Statoil Australia Oil & Gas AS) are encouraged by these early stage results and look forward to flow-testing this well. This data will be used to guide the 2013 capital program as it supports the potential for oil recovery in PetroFrontier's unconventional acreage. MacIntyre-2H A successful hydraulic stimulation was performed on the MacIntyre-2H well over nine open-hole stages. However, after recovering approximately one-third of the hydraulic stimulation fluid, traces of biogenic hydrogen sulfide gas, produced from naturally occurring organisms in the completion fluid, were detected and the well had to be suspended. PetroFrontier is actively sourcing the specialized equipment to allow flow-testing to resume. Based on the experience at the MacIntyre-2H well, additional treatment of the completion fluid was performed prior to stimulation operations at the Owen-3H and Baldwin-2Hst1 wells to avoid a reoccurrence of this problem. Baldwin-2Hst1 During the hydraulic stimulation program of the Baldwin-2Hst1 well, a shallow casing failure occurred and as a result, PetroFrontier was unable to complete the program. As expected, the multiple casing design protected the shallow aquifers. PetroFrontier plans to carry out remedial work to repair this well so that the planned hydraulic stimulation program can be completed.
