Press Release Source: Petrobank Energy and Resources Ltd. Petrobank Closes Southeast Saskatchewan Acquisition Tuesday May 1, 10:50 pm ET CALGARY, ALBERTA--(CCNMatthews - May 1, 2007) - Petrobank Energy and Resources Ltd. ("Petrobank" or the "Company") (TSX:PBG - News; OSLO:PBG - News) is pleased to announce that it has closed the acquisition (the "Acquisition") of land and reserves previously disclosed in our press release dated April 9, 2007 relating to the expansion of our asset base in the Bakken light oil resource play. Today, Petrobank acquired a 50% working interest in certain producing properties in the Viewfield/Stoughton area of southeast Saskatchewan, with extensive undeveloped acreage and an ongoing farm-in with a third party, for $8.5 million. ADVERTISEMENT The Acquisition enhances the core of Petrobank's recently expanded position on the Bakken light oil play in southeast Saskatchewan. Under the original farm-in agreement related to the Acquisition, the previous operator drilled four (2.0 net) Bakken horizontal oil wells which are currently producing 80 (40 net) barrels of oil/day. The Acquisition includes 9,426 (4,813 net) undeveloped acres and we have the potential to earn a further 13,598 (6,799 net) acres with additional drilling. In a reserve report dated effective December 31, 2006, McDaniel and Associates Consultants Ltd. assigned total proved reserves of 251,000 barrels, and total proved plus probable reserves of 730,000 barrels, to these acquired lands. Petrobank plans to fracture stimulate the existing four producing wells and drill additional Bakken horizontal oil wells to earn the remainder of the lands. These lands are located within the core of our Bakken fairway, and are contiguous with our existing land position. Inclusive of the 41,800 acres acquired at the Saskatchewan crown land sale in April 2007, our acreage position on the Bakken fairway is now approximately 138,000 (114,000 net) acres. The addition of these lands obtained through the Acquisition further enhances our ability to build critical operating mass in the area, which allows us to optimize our facilities for production of oil and also the ultimate recovery of significant volumes of solution gas and natural gas liquids from our Bakken wells. Petrobank currently has two drilling rigs working our Bakken lands and we plan to increase this to four rigs by the third quarter of this year. All recently acquired lands are highly prospective for Bakken light oil and are expected to yield up to four horizontal wells per section (one section equals 640 acres). Currently, we estimate our Bakken drilling inventory at 550 (500 net) wells. With these recent acquisitions, the Bakken light oil resource play is expected to be our Canadian Business Unit's primary focus area in 2007 and for years to come. Our highly effective Bakken drilling and stimulation program, along with the expansion of our land base, has strategically positioned Petrobank to be a key Bakken light oil player.
