Title: Identification of Residual Oil Zones in the Williston and Powder River Basins

Abstract

The goal of this project by the Energy & Environmental Research Center was to systematically assess the petroleum systems of the Williston and Powder River Basins (PRB) for prospective residual oil zones (ROZs) through a geologic process modeling approach. This approach models the evolution of a sedimentary basin to predict if, when, and where reservoirs were charged with hydrocarbons. Suspected ROZs identified by this approach were evaluated for their potential oil recovery using carbon dioxide (CO 2) and for associated CO 2 storage. ROZs are naturally waterflooded portions of oil reservoirs with oil saturations between 25% and 40% but are at irreducible oil saturation levels with respect to water, rendering the reservoirs uneconomic using conventional recovery methods. However, using CO 2 enhanced oil recovery (EOR), substantial amounts of oil can be recovered from ROZs while simultaneously storing CO 2. ROZs were originally identified and defined in the Permian Basin of West Texas but have since been identified or speculated in several geologic basins, including the Williston Basin and PRB.
