Z. Jiao P. Stauffer T. Miller R.C. Surdam 2011 <p id="sp000005">The Wyoming State Geological Survey has completed a thorough inventory and prioritization of all Wyoming stratigraphic units and geologic sites capable of sequestering commercial quantities of CO₂<span>&nbsp;</span>(5–15&nbsp;Mt CO₂/year). This multi-year study identified the Paleozoic Tensleep/Weber Sandstone and Madison Limestone (and stratigraphic equivalent units) as the leading clastic and carbonate reservoir candidates for commercial-scale geological CO₂<span>&nbsp;</span>sequestration in Wyoming. This conclusion was based on unit thickness, overlying low permeability lithofacies, reservoir storage and continuity properties, regional distribution patterns, formation fluid chemistry characteristics, and preliminary fluid-flow modeling. This study also identified the Rock Springs Uplift in southwestern Wyoming as the most promising geological CO₂<span>&nbsp;</span>sequestration site in Wyoming and probably in any Rocky Mountain basin.</p><p id="sp000010">The results of the WSGS CO₂<span>&nbsp;</span>geological sequestration inventory led the agency and colleagues at the UW School of Energy Resources Carbon Management Institute (CMI) to collect available geologic, petrophysical, geochemical, and geophysical data on the Rock Springs Uplift, and to build a regional 3-D geologic framework model of the Uplift. From the results of these tasks and using the FutureGen protocol, the WSGS showed that on the Rock Springs Uplift, the Weber Sandstone has sufficient pore space to sequester 18&nbsp;billion tons (Gt) of CO₂, and the Madison Limestone has sufficient pore space to sequester 8&nbsp;Gt of CO₂.</p> application/pdf 10.1016/j.egypro.2011.02.373 en Elsevier The key to commercial-scale geological CO2 sequestration: Displaced fluid management article
