“…Identification of stacking patterns and grain size trends in fluvial deposits is important, because grain size and sorting exert strong controls on reservoir porosity and permeability (Selley 2000). Although grain size variance is relatively low in fine-grained fluvial reservoirs, the coarsest grained and highest energy lithofacies typically exhibit greater absolute porosity and permeability than finer-grained, lower energy lithofacies (e.g., Chapin et al 2014). Therefore, understanding the 3D distribution of porosity and permeability in reservoirs is necessary for constructing and conditioning representative reservoir models that form the basis for well-completion and field-development strategies (Ebanks 1987).…”

This section describes project activities undertaken to complete geologic characterization of Noble, Kenner West, and Loudon Fields. A range of project activities were completed at each study site including stratigraphic correlation, sedimentary facies analyses, and identifying petrophysical characteristics of the reservoirs present in a specific field. Isopach maps were developed which show variation in the thickness and geometry of the thick Cypress Sandstone. This work facilitated the broader, regional geologic characterization of the Cypress Sandstone (see Section 3.4).While a range of project activities were conducted in order to complete field-scale geologic characterization, not all project activities pursuant to this goal were undertaken at each individual field. At Noble, project activities included both stratigraphic and facies analyses as well as reservoir characteristics (i.e., reservoir geometry, volumetric analysis, and isopach maps). At Kenner West, project activities included stratigraphic analysis and reservoir characteristics (i.e., reservoir geometry, volumetric analysis, and isopach maps). At Loudon, project activities were limited to stratigraphic analysis and reservoir characteristics (i.e., reservoir geometry and isopach maps).
