The purpose of this study was to use hydrodynamic interpretation for delineating exploration fairways. First, gross reservoir continuity, as it relates to individual Halfway sand cycles, was determined, followed by the delineation of areas of high entrapment potential due to either stratigraphic, erosional, or structural terminations observed as "pressure discontinuities". The final stage include reservoir continuity analysis, bypassed pay analysis, determination of fluid contacts for identified hydrocarbon accumulations, and specific prospect recommendations and delineations.

The study area includes NTS BLOCKS 94-A-13,14,15; 94-B-9,16; 94-G-1,8,9; and 94-H-2,3,4,5,6,7,10,11,12 along with Townships 87-88, Ranges 17-26 W6 in northeastern British Columbia. The study area has approximately 3,500 wells that penetrate the Halfway. The database compiled for the evaluation consisted of 1,302 DSTs, of which 673 had usable pressures and 38 AOF pressures. The dataset for this evaluation included data indicated as both Halfway and Doig, as it was determined that the Halfway and Doig Formations were hydraulically indistinguishable across the area. The Halfway Formation in the Buick Creek-Martin-Redeye area comprises three play types. The first play type is restricted structural traps in hydraulic systems with regional continuity. The second play type is restricted stratigraphic traps associated with the updip erosional edge of the Halfway Formation. A majority of the current gas production occurs from this play type. The third play type is stratigraphic traps associated with depositional facies variations within the Halfway Formation and the hydraulic breaks that reflect these variations. This play type has the strongest trapping potential, but also has the highest implied reservoir risk.
