The objective of the Ferron Sandstone project was to develop a comprehensive, interdisciplinary, quantitative characterization of a fluvial-deltaic reservoir to allow realistic inter-well and reservoir-scale models to be developed for improved oil-field development in similar reservoirs world-wide. Quantitative geological and petrophysical information on the Cretaceous Ferron Sandstone in east-central Utah was collected. Both new and existing data were integrated into a three-dimensional model of spatial variations in porosity, storativity, and tensorial rock permeability at a scale appropriate for inter-well to regional-scale reservoir simulation. Simulation results could improve reservoir management through proper infill and extension drilling strategies, reduction of economic risks, increased recovery from existing oil fields, and more reliable reserve calculations. This 471-page report describes the geological and petrophysical characteristics of the fluvial-deltaic Upper Cretaceous Ferron Sandstone. The report includes Ferron facies analysis, regional sequence stratigraphy, evaluation of three case-study areas, geostatistics, and a 3-D oil and gas reservoir simulation of the Ferron.

This study characterizes and interprets the fluvial systems responsible for deposition of the Poison Strip sandstone through analysis of extensive field data and comparison to ancient fluvial systems. Conclusions on fluvial style are related to depositional controls and to regional Lower Cretaceous rocks.
