DEVELOPMENT POTENTIAL
Belloy Formation: There are four step-out Belloy oil locations based on current producing wells and a dolomitic pay map of the productive interval. Three of the locations are to the northwest of 01-16-085-19W6 which has produced 133 Mbbl, 230 MMcf, with a current rate of 32 bbl/d of oil (Aug. 2010). The fourth location is in section 10 to the southeast of 13-10-085-19W6 which has produced 206 Mbbl, 215 MMcf, with a current rate of 33 bbl/d of oil (Aug. 2010).
Currently the 04-15-085-19W6 horizontal well has the potential to produce at 500 bbl/d of oil but is limited by daily allowance to produce for 60 hours/month. The current rate for the 04-15 well is ~60 bbl/d and this will double to ~120 bbl/d once the allowance application has been approved. The Company’s after-payout interest in this well is 41.25%. Payout timing will be accelerated with the increase of the allowable rate.
The potential exists in the Belloy to initiate a waterflood that will significantly increase the recovery factor. The GOR is increasing and the watercut is dropping indicating little or no pressure support. Currently, there are two active waterfloods within one township of the West Eagle area that have shown positive waterflood results. To the west, Devon and Terra Energy have been injecting water and gas into the Belloy C Formation since the early 1990's. The watercut has been rising in recent years but they have been able to maintain a steady GOR with consistent water injection since implementing the flood. To the east, Devon is the operator of a larger-scale waterflood in the Belloy A Pool. Water injection commenced in the mid 1980's and the benefit from the flood can be seen on the plot on this page.
Potential exists to infill drill at an 80-acre well spacing similar to the Belloy A and C pools.
Montney Formation: In the West Eagle area the fine-grained sediments of the Montney were deposited in a distal marine setting. Occasionally within the lower part of this marine sediment package coarser turbidite packages are observed. In general the Montney in this area is split into two gross packages, the Upper and the Lower Montney separated on wireline logs by a Mid-Montney flooding surface and an overall shift from lower density porosity response in the lower interval to a higher density porosity response in the upper interval.
The Montney in the Stoddart area is found at a depth range of 1,600-2,000m with density porosities upwards of 9-11%. One example of a potential Montney completion is the 03-10-085-19W6 (41.25% WI). The Upper Montney, between 1,675-1,752m has porosities of 9-11% and is similar in both thickness and porosities as the 13-33-080-16W6 Parkland well. The 13-33 vertical well is in the middle of the horizontally developed Upper Montney of the Parkland Field to the southeast in Townships 80-81, Range 16W6. At Parkland, the horizontal development of the Montney surrounding the 13-33 well has wells with monthly production rates in excess of 5 MMcf/d.
In addition to a similar Upper Montney package in the 03-10 well, there is also a turbidite package in the lower part of the Montney that is 20m thick, has sandy/coarser-grained intervals and density porosities between 3-6%.
Both the lower Montney turbidite package and the Upper Montney interval have potential for vertical well testing. With success in one or both of these intervals, follow-up horizontal wells would be planned.
