An Integrated Reservoir Simulation and Geomechanical Modeling of CO₂ Injection at the Wyoming Dry Fork CarbonSAFE Geologic Storage Complex Available to Purchase

The Wyoming CarbonSAFE project is located at the Powder River Basin (PRB) in northeast Wyoming, which aims to safely store over 50 million metric tons of CO₂ for a period of 30 years at three stacked reservoirs including Lakota sandstone, Hulett sandstone, and Upper Minnelusa formation. Site-specific characterization data, including well logs, seismic data, core data, and field tests, are integrated into the dynamic model for initializing reservoir pressure and regional stress state and estimating petrophysical and rock mechanical properties. An integrated reservoir simulation and geomechanical modeling are then performed to estimate the well injectivity, storage capacity, surface displacement, integrity of reservoir and caprock, and fault stability. The presented workflow demonstrates how the stacked storage approach helps with large-scale geologic carbon sequestration within structurally complex reservoirs.
