BEAVERDAM DEVELOPMENT POTENTIAL / GEOLOGY
Production in the Beaverdam area is largely from Lower Cretaceous, Jurassic, and Triassic sediments. Producing and prospective intervals include the Bluesky, Gething, Nordegg, Baldonnel, Charlie Lake, and Halfway Formations.
Bluesky Formation: In the Beaverdam area, the Bluesky geology is similar to the Currant area. The Bluesky occurs at depths ranging from 975 to 1,010m, thickness averages ~3.5m, and reservoir porosity is up to 15%.
There is a potential re-completion in the Bluesky zone in the d-003-I/094-A-15 well. This well shows similar log characteristics to the offsetting c-020-L/094-A-16 well which has produced 625 MMcf of gas since completion in 2004 and was still producing ~170 Mcf/d as of August 2010.
Gething Formation: The Gething Formation in the Beaverdam area consists of very fine to fine-grained sandstones that were deposited in a network of distributary channels trending in a northeastern direction. The channels consist of fining upwards successions and reservoir quality sands have porosities >12%.
One unbooked Gething horizontal drilling location, d-006-D/094-H-01, and two Gething tie-in wells, c-005-D/094-H-01 and b-016-D/094-H-01, could provide additional upside reserves for the Beaverdam area.
The cross section A-A’, shown above, through two standing wells on Company lands illustrates porosity distribution in the Gething (reaching up to 15%) and the overall thickness (~35m). Despite the low net pay (based on a 12% porosity cut-off) the c-005-D/094-H-1 well had a final flow rate of 42 bbl/d of oil during testing. The b-016-D/094-H-01 well had test rate of 43 bbl/d and 162 Mcf/d. Application of horizontal drilling and multi-stage fracturing techniques to the Gething in this area may increase flow rates and more effectively access reserves in lower-quality sandstones. The 9% porosity cut-off shown on the logs illustrates the additional oil-bearing rock that could be exploited with horizontal wells. The cost of drilling horizontally will be reasonable given the relatively shallow depth of the Gething at ~975m.
Halfway Formation: Similar to the Currant area, the Halfway reservoir at Beaverdam consists of isolated sandstone bodies. These sands have an average thickness of 5m and porosities up to 27%. Depth of the Halfway over the Beaverdam area is between 1,100 and 1,160m.
Two drilling locations targeting the Halfway have been identified, c-002-I/094-A-15 and d-093-H/094-A-15. d-093-H has been booked as a Proved Undeveloped location with reserves of 194 Mboe and an initial production rate of 110 boe/d. The cross section on this page, B-B’, illustrates the Halfway location projected between a producing well on Company lands correlated to a well within the CNRL-operated PeeJay Unit #3-PMWF. The offsetting Company well, d-003-I/094-A-15, was producing 65 bbl/d of oil and 143 Mcf/d of associated gas as of August 2010; this well is capable of producing at higher rates but was limited by allowables.
