CO2 plume modeling in deep saline reservoirs by 2D ERT in boreholes

Abstract

The need to manage [Formula: see text] emissions for mitigating the greenhouse effect has led to worldwide research to reduce atmospheric [Formula: see text]. Techniques of carbon capture and storage (CCS) must (1) be effective and cost-competitive, (2) provide stable, long-term storage, and (3) be environmentally benign. Potential terrestrial media for [Formula: see text] storage include depleted oil and gas reservoirs, coal seams that cannot be mined, and deep saline water reservoirs capped by impermeable rock to prevent upward leakage.
