DEBOLT

The Debolt Formation in the Manning area can be subdivided into Debolt A, Debolt B and Debolt C. Outside the Manning area another unit can be found, the Debolt D, adds to the overall thickness of the Debolt of approximately 90 m. The Debolt A unit overlies the Elkton Member, separated by an 8 to 13 m thick, relatively impermeable shaley carbonate to shale interval. At Manning, the Debolt A is the most prospective zone and the zone that is mapped and at the erosional edge.

Previous operators have drilled wells in the Debolt Formation, testing its heavy oil potential. The erosional edge is where optimal oil trapping occurs and where commonly the highest porosity and permeability is developed.

Mapping of the Elkton erosional edge suggests that most of the prospective geology occurs on CEC lands. Likewise, mapping of the Debolt (actually Debolt A, referred to as Debolt) also suggests that the most prospective Debolt heavy oil potential also occurs on CEC lands.

Oil Trapping, Mapping Parameters and Seismic Evaluation

A net pay map of the Debolt and is based on the same parameter cutoffs that were used to map the Elkton (i.e., 18% porosity, 100 ohm-meters resistivity). A cross-section that was shown previously demonstrates the trapping mechanism of heavy oil in the Debolt at Manning.
The net pay area of the Debolt is smaller than the Elkton’s, and the structure is slightly lower (more downdip), perhaps suggesting that the oil quality may be slightly lower than the exceptional Elkton oil. Internal reserve calculations of the Debolt net pay map, based on the rigorous pay cutoffs, are 400 million barrels PIIP (internal estimate). **PIIP estimate combination of Third Party and Corporate Estimates.
