• The Carnian Charlie Lake Formation is a hydrocarbon bearing formation found predominantly in northeastern British Columbia, Canada. Aeolian sand bodies are present in both the subsurface and outcrop occurrences, and in fields like Brassey, are the primary hydrocarbon reservoir. For this study, 2 outcrop occurrences of Charlie Lake Formation in its entirety (Brown Hill and Schooler Creek) and a case study on the Artex member sandstone involving 15 cores from Brassey Field were evaluated. Although non-correlatable, the relationships between the outcrop and subsurface Charlie Lake Formation were assessed and, show similar preservation of the coastal dune bodies, related to deposition in shore-parallel depressions that were initiated as lagoons or lakes. Consequently, it is proposed that preserved aeolian dune thickness is directly related to lagoon / lake depth, which in turn is likely related to local tidal regime.
