VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 13, 2012) - Big Sky Petroleum Corporation (TSX VENTURE:BSP) has completed fracture stimulation of its first well, (14-29) completed the vertical drilling and casing of its second well (15-13), permitted for a third well (4-3) and is working on permitting for a fourth well (81-4).

The 14-29 Well located in Sec 29-35N-1W of Toole County, Montana has been fracture stimulated and is currently undergoing testing and evaluation. The approximate 4,100 feet lateral section targeted the Middle Bakken Formation. Further results are expected to be received in March. This data will determine the potential economics of this well and will also be used for planning fracturing completions for future wells including the 15-13 Well.

The 15-13 Well is located approximately 3 miles south-west of the 14-29 Well and was vertically drilled and cased. The next operation planned for this well is horizontal drilling and completion including a planned 26 stage fracture stimulation. This operation is scheduled for the second quarter.

Permitting has been obtained on a new well - the 4-3 Well - which is anticipated to be spud in the second quarter.

The 81-4 Well is another new well located in Glacier County, Montana, and is expected to receive permitting approval by the end of March. Once approval for the 81-4 Well has been obtained, the first phase of drilling this new well will be completed. Big Sky previously re-entered, deepened, and stimulated the 81-3 Well which confirmed the presence of oil and provided the basis for drilling the 81-4 Well.

Sam Nastat, President of Big Sky, commented that, "We continue to be very optimistic about our exploration program and our early entry into the Alberta Bakken. The team has done a great job in completing work for each well and we plan to continue this level of activity during 2012."
