As quoted in the press release:
Hyperion has a goal, as it grows, to continually add internally sourced assets with greater total petroleum initially in place (“TPIIP”) and repeatability. To meet this objective, Hyperion has recently acquired new undeveloped land and farm-in providing for a combined total of 35,680 gross (32,515 net) acres of Cardium rights in the Niton/McLeod area, with an average working interest of approximately 90%. TPIIP effective as of August 15, 2012, is internally estimated to be up to 171 MMbbls of light oil and a primary recovery factor of 12.5%. The new undeveloped acreage and farm-in is expected to add up to 177 gross (158 net) Cardium light oil wells to Hyperion’s corporate drilling inventory.
