Abstract
"Carbon dioxide (C0₂) sequestration has been extensively implemented and explored predominantly in depleted oil reservoirs and deep saline aquifers where the C0₂ is stored under supercritical conditions. A lesser explored option with great potential is based on injection into shallow reservoirs where the C0₂ may not always be in its denser supercritical state. The research evaluates the potential for injecting C0₂ into saline aquifers at depths of ~550-650 meters and formation temperatures of -22⁰C.
To evaluate injectivity and cap rock integrity, reservoir and geomechanical simulations need to be conducted separately and subsequently coupled. A Shared Earth Model is developed utilizing a unique methodology which enables utilization of an extensive dataset ranging from regional geological and topographical maps, more than 190 water wells including an on-site exploratory well, core observations, well logs and core laboratory tests relevant to a possible injection site in Springfield, Missouri.
Petrophysical characterization conducted indicates presence of suitable caprock and storage formations required for C0₂ injection. Regional stress analysis of the region evaluates safe pressures for injection without fracturing the well bore region.
Subsequent on-site C0₂ injection simulation of the upscaled geologic model implementing single well and multiple well injection scenarios under closed volume conditions indicate limited injectivity potential of approximately 2% of C0₂ emissions from a typical 490MW power plant"--Abstract, page iii.
