Gas Production from the Permian

Gas production from the Permian is primarily derived from the Belloy Formation in the Peace River Block area of northeast B.C., as well as from scattered Belloy fields us west-central Alberta.

There are seven Permian gas fields with Initial Established Marketable Gas Reserves of over 1000x l0⁶m³(35 BCF). These seven largest Permian gas fields, listed in order of Initial Established Marketable gas reserves, are shown in Table 1. Cumulative production data for Alberta and British Columbia arc updated to the end of 1990.

No.	Field	Formation	No. of Pools	Marketable Reserves	In-place Volume	Cumulative Production	Discovery Year
1	Stoddart	Belloy	2	8,252	9,170	7,208	1957

The first four of these Permian gas fields occur in structural-stratigraphic traps in the Peace River Block of northeast B.C. and the last three in west-central Alberta.

Total recoverable gas reserves in the Permian are estimated at 73.0 x 10⁹m³, of which 20.2 x 10⁹m³ have already been produced. Initial Established In-Place Volume of Permian gas reserves totals 95.2 x 10⁹m^3. There are a total of 218 Permian gas pools, With an average 334 x 10⁶m³ recoverable gas reserves/pool. Table 2 lists the distribution of Permian gas reserves according to In-Place Pool Size.

In-Place Pool Size Class	No. of Pools	Recoverable Reserves	Cumulative Production
1.0 to 10	4	15	10
10 to 100	67	2,481	502
100 to 1000	136	34,033	6,017
1000 to 10000	10	18,467	13,690
over 10000	1	18,000	0
Total	218	72,997 x 10⁶m³	20,220 x 10⁶m³
