Inverse geochemical modeling of groundwater entails identifying a set of geochemical reactions which can explain observed changes in water chemistry between two samples that are spatially related in some sense, such as two points along a flow pathway

A semi-analytical model for simulating injection of an immiscible fluid into a water-filled reservoir is developed which approximates the effects of horizontal injection wells, impermeable fault segments, and permeability anisotropy on phase saturati

The Mount Simon sandstone and Eau Claire shale formations are target storage and cap rock formations for the Illinois Basin-Decatur Geologic Carbon Sequestration Project. We reacted rock samples with brine and supercritical CO(2) at 51 °C and 19.5 M

The In Salah project (a joint venture of BP, Statoil and Sonatrach) includes a CO 2 sequestration effort that has successfully injected millions of tons of CO 2 into a deep saline formation close to a producing gas field in Algeria. We have performed

It is important to determine the geochemical reactions between common cements used in wellbore construction, formation mineralogy, and supercritical CO 2 stored in deep saline reservoirs, because abandoned and completed wells provide a pathway for re

Large-scale carbon capture and storage projects involve injecting CO 2 into a porous, permeable formation that is overlain by an impermeable “caprock”. The In Salah Project (a joint venture of BP, Statoil and Sonatrach) includes a CO 2 sequestrat

Forensic analyses of chlorinated hydrocarbon plumes typically entail reviews of site records, flow and transport modeling, and analysis of indicator compounds to gain insights into the behavior of a contaminant plume in the subsurface. Such approache
