Résumé(disponible en anglais seulement)
Part I of this paper describes the discovered gas resources of the major Carboniferous and Permian gas plays in flat-lying strata beneath the Interior Plains of western Canada. It presents a prediction for their undiscovered gas resources based on geological and statistical analysis. In Carboniferous strata in the plains, 587.208 x 109 m3 (20.8 TCF) total discovered gas occurs in five established, mature Carboniferous plays, present in 241 fields with 883 pools. This represents 53 per cent of the in-place gas volume for the Carboniferous and Permian plays (plains plus Foothills). The potential of initial volume in-place gas in these five plays is 142.041 x 109 m3 (5.0 TCF), predicted to occur within 3177 undiscovered pools. Thus, 19 per cent of the Carboniferous (plains area) gas-in-place resource in mature plays remains to be discovered. There are four immature plays identified for the Carboniferous in the plains and they contain 2.711 x 109 m3 (0.1 TCF) of initial volume in-place gas in 10 gas fields, each consisting of one pool. The potential in the immature plays was incorporated in the conceptual play analysis.
For the Permian in the plains, 39.943 x 109 m3(1.4 TCF) occurs within one established mature play, in 48 fields with 93 pools. This represents 96 per cent of the gas-in-place total for the Permian (plains plus Foothills). The expected potential of initial volume in-place gas in the plains is predicted to be 72.783 x 109 m3 (2.6 TCF), within 907 undiscovered pools in the established play. The total number of discovered and predicted Permian pools (plains area) is 1000. Almost 65 per cent of the Permian gas-in-place resource in the plains remains to be discovered. No immature plays were identified for the Permian.
The potential gas volume in the conceptual and immature plays within the Carboniferous and Permian of the plains is 285.909 x 109 m3 (10.1 TCF). This statistical analysis predicts about 22 plays in the Carboniferous and Permian, representing six mature plays, four immature plays, and 12 conceptual plays. For comparison, at least 5 to 10 conceptual plays are suggested on the basis of our regional geological analysis.
For the Carboniferous and Permian of the plains, the discovered initial volume in-place gas for all established, mature and immature plays is 629.862 x 109 m3 (22.4 TCF), within 296 fields and 986 pools. The total initial volume in-place gas resource (discovered and undiscovered) for all mature, immature and conceptual plays is 1130.595 x 109 m3 (40.1 TCF), predicted to occur in 5070 discovered and undiscovered pools within the mature plays, plus an undetermined number of undiscovered pools in the conceptual and immature plays. The undiscovered potential of 500.733 x 109 m3 (17.8 TCF) for all play types represents 44 per cent of the total gas resource in the plains area.
