CSPG18FT The Triassic of Northeastern British Columbia: Sedimentary Characteristics & Stratigraphic Architecture of Conventional and Unconventional Reservoir Successions
The Williston Lake Triassic field trip provides industry scientists with an opportunity to analyse outcrop equivalents of all Lower, Middle and Upper Triassic conventional and unconventional reservoir units. These include outcrop of fine-grained shale and silt-dominated successions (Doig and Montney equivalents) as well as outcrop analogues of Montney turbidites, Doig and Halfway offshore, shoreface and tidal inlet channel successions, Charlie Lake Formation sand dunes and tidal flat dolomite beds, Baldonnel shallow shelf carbonates and Pardonet offshore carbonates.
The field tip is subdivided into core and outcrop components. On the first day of the trip the participants shall spend the day in the BCEMPR core repository in Charlie Lake, BC. Core from a variety of fields will be observed with a strong emphasis on core from fine-grained intervals (‘shale’ gas plays) in the Montney and Doig Formations. Core through conventional reservoirs in the Doig, Halfway, Charlie Lake and Baldonnel Formations will also be discussed.
The outcrop component will focus on Triassic outcrop on the shores of the Peace Reach of Williston Lake. Over three days participants will observe Triassic successions at eight outcrop stops. Formations observed will include the Grayling and Toad Formations (Montney-Doig equivalents), Liard Formation (Halfway equivalent), Charlie Lake, Baldonnel and Pardonet Formations. Lithofacies observed in outcrop are identical to those observed in the subsurface to the east providing a unique opportunity to assess and discuss reservoir attributes and geometries. Field Trip participants will stay at Wicked River Lodge, on the north shore of Williston Lake.
