Chapter 14 Table Oil Production from the Shunda/Pekisko - Mission Canyon

View Table 14.32a2 as an image.

Major oil production from the Shunda and Pekisko formations and their Frobisher/Alida/Tilston equivalents occurs in southeast Saskatchewan and southern and central Alberta. Most of this production is located in stratigraphic traps along the erosional unconformity.

There are 25 Shunda/Pekisko oil fields with Initial Established Recoverable Oil Reserves of over 1 x 10⁶m³ (6 MMBbls). Twenty of these major fields are in Saskatchewan. The ten largest Shunda/Pekisko oil fields, listed in order of Initial Established Recoverable Reserves, are shown in Table 1. Cumulative production data for Alberta are updated to the end of 1990 and for Saskatchewan to the end of 1989.

Table 1. Ten Largest Shunda /Pekisko Oil Fields (in units of 10⁶m³).

Seven of these ten largest Shunda/Pekisko oil fields occur in Frobisher/Alida/Tilston beds along the wedge edge in southeast Saskatchewan. The remaining three, Twining, Sylvan Lake and Medicine River, occur along the wedge edge in south-central Alberta. The most recent major Shunda oil discovery was in the Desan area of northeast B.C. in 1983. All Shunda/Pekisko oil fields contain light to medium gravity oil, with the exception of a few of the smaller Alberta fields.

Total recoverable oil reserves in the Shunda/Pekisko are estimated at 107. 5 x 10⁶m³, of which 82.2 x 10⁶m³ have already been produced. Initial Established In-Place Volume of Shunda/Pekisko oil reserves totals 653.9 x 10⁶m³. There are a total of 209 Shunda/Pekisko oil pools, with an average 514 x 10³m³ recoverable oil reserves/pool. Table 2 lists the distribution of Shunda/Pekisko oil reserves according to In-Place Pool Size.
