Bell Creek Test Site - Preinjection Geochemical Report

Creative Commons Attribution Share-Alike

Specific efforts summarized in this report include the following: • Analysis of rock samples within the CO2 injection zone (Muddy Formation) as well as on the sealing formations (Niobrara and Mowry Formations) to determine their petrographic, petrophysical, and mineralogical characteristics. • Reservoir fluid sampling and analysis to characterize the formation water chemistry and to better understand the hydrocarbon composition of the reservoir. • Surface water, groundwater, and shallow vadose zone soil gas sampling and analysis to establish baseline characteristics of surface and shallow subsurface environments prior to CO2 injection. v • Preliminary review of existing literature to identify potential mineralogical effects of CO2 injection within the Bell Creek reservoir and cap rock and also within the overlying groundwater zones in the unlikely event of out-of-zone migration. • Laboratory-based CO2 exposure testing of rock and water samples from the lowest groundwater zone (Hell Creek Formation) overlying the Bell Creek reservoir to better understand the possible effects of out-of-zone CO2 migration to the shallow subsurface.
