Chapter 23 Table Gas Production from the Cardium

View Table 23.2b as an image.

Gas production from the Cardium is concentrated in southwestern Alberta adjacent to the disturbed belt. As well, minor gas production occurs in western Saskatchewan. Included are fields producing from the Cardium in Alberta and the St Walburg Sand in Saskatchewan.

There are 12 Cardium gas fields with Initial Established Marketable Gas Reserves of over 1000 x 106m3 (35 BCF). The ten largest Cardium gas fields, listed in order of Initial Established Marketable gas reserves, are shown in Table l. Cumulative production data for Alberta are updated to the end of 1990.

Much of the gas production from the Cardium is closely associated with oil production, with both often being produced from the same field.

Total recoverable gas reserves in the Cardium are estimated at 88.3 x 109m3, of which 30.8 x 109m3 have already been produced. Initial Established In-Place Volume of Cardium gas reserves totals 263 x 109m3. There are a total of 289 Cardium gas pools, with an average 305 x l06m3 recoverable gas reserves/pool. Table 2 lists the distribution of Cardium gas reserves according to In-Place Pool Size.
