Regional Geology
The Nisku P Pool produces sour gas and condensate from the Nisku carbonate shelf reservoir in T.48 R.12 W5 under a gas cycling program. The Nisku carbonate shelf edge in the Brazeau area is regionally controlled by the topography of the underlying Ireton clinoform surface. Horizontally accreted Nisku shell reservoirs can grow on the Ireton shelf out to the limit of the Ireton clinoform edge. Beyond this break in the slope to the north, isolated deeper water Nisku pinnacles are vertically accreted reef growths. The difference in style of accretion (vertical vs horizontal) results in the horizontally accreted Nisku shelf reservoirs being thinner but more areally extensive and continuous than the vertically accreted pinnacles. This difference in style is well illustrated by the Nisku P pool, which covers approximately 16 sections above its gas/water line. In addition, the Nisku shelf reservoir in the P pool thickens significantly along the northern edge of the pool.
Nisku P Pool and Section 15
The attached net pay map shows that section 15 contains a significant portion of the gas pay in the pool. Section 15 is bounded by gas pay in 7-14, 7-10, 11-9 and 3-16. The net gas pay map is contoured to honour these control points, and to be consistent with the model of thicker reservoir due to carbonate buildup along the northern edge of the pool. Gas cycling applications for the Nisku P pool submitted by the pool operators over time have assigned more pay to the NE part of the pool than the well data indicates in order to obtain a history match with production and pressures. It is significant that the estimated original gas in place keeps increasing with each history match, indicating that the pool is larger than originally estimated. This concept was recently proven by the new 7-14 well, which not only enlarges the pool boundaries, but contains the thickest gas pay encountered to date in the pool. A recent well was drilled at 15-18 to further evaluate the thicker pay along the northern part of the pool, as is an indicated gas well. Based on well control, section 15 contains net gas pay thickness somewhere between the high (46m) and low (6.2m) extreme values in the bounding wells.
Seismic data through Section 15 can be directly compared to seismic data over the 7-14 gas well, and clearly shows that section 15 contains a similar carbonate buildup on the edge of the P pool. The 7-14 well is currently producing 19mmcf/d raw gas with 3200 bopd condensate.
Because of the gas cycling scheme, even a thin pay section in the updip portion of the pool at section 15 would be a prolific producer. The 11-9 well has only 9m of pay, but is currently producing at 18.5 mmcf/d raw gas yielding 2542 to 3138 bopd NGL's and condensate. The Nisku P pool has been producing under the current gas recycling pattern since 1991. The gas cycling plan submitted for the pool in 1992 forecasts production to continue to the year 2021, with dry gas blowdown beginning in mid 2004.
