ABSTRACT

Exposures of the Ferron Sandstone Member of the Cretaceous Mancos Shale formation, east-central Utah provide large-scale cross-sectional views of valley-fill sandstone bodies within a well-constrained sequence stratigraphic framework. Quantitative data collected from these outcrops help constrain the modeling of interwell volumes of analogous valley-fill reservoirs and permit a better evaluation of reservoir potential. The study has implications for how heterogeneities should be modeled in analogous reservoirs. Differences in net-to-gross, connectivity, and petrophysical property structure of valley-fill deposits can be related to stratigraphic stacking pattern (progradational versus aggradational) and position along depositional profile (proximal versus distal).
