PETROPHYSICAL EVALUATION OF THE BLUESKY SAND, BASSETT AREA, ALBERTA.

The Lower Cretaceous Bluesky sand of the Bassett Area in northwestern Alberta produces gas from a series of structural-stratigraphic traps formed as the Bluesky sand follows the structural configuration of the pre-Cretaceous unconformity. A hydrodynamic analysis of the Bluesky sand drill-stem tests indicates a number of pressure systems, each with a separate gas-water contact. Miami Amoco Bassett 10-16-105-1 W6 and Amoco Miami A-1 Bassett 6-12-105-1 W6 are situated in the same pressure system and are structurally above a gas-water contact. These wells have the same recovered significant volumes of gas upon evaluation. Can Hunter et al. Haig 10-34-104-3 W6 is located in a separate pressure system to the west and is also structurally above a gas-water contact, but failed to recover gas upon evaluation.
