Abstract
The Paskapoo formation is composed of several hundred meters of heterogeneous fluvial strata that were deposited in the subsiding foreland basin of the Canadian Cordillera. The Alberta government require the gamma ray log from petroleum wells to be collected through this formation. The first step in utilizing this new data is to correct for the suppressive effect that surface casing has on the natural gamma ray response. A simple and efficient method was used to normalize the gamma ray data collected through surface casing. The method adjusts the cased gamma ray values so that the maximum and minimum of the distribution are equal to those of non-cased values. Net-to-gross maps and stratigraphic cross-sections identify a megafan/DFS in the north and variation in the fluvial stratigraphy across the study area. Tectonic activity is interpreted as the primary control on fluvial stratigraphy, controlling the variable ratio of sediment flux to accommodation creation.
