Abstract

ARCENTALES-BASTIDAS, Danilo et al. Sensitivity analysis of the impacts of operational and geologic conditions on Area of Review (AOR), Post Injection Site Care (PISC) and Risk associated with CO2 Sequestration in South-region of United States. RCTU [online]. 2017, vol.4, n.3, pp.1-12. ISSN 1390-7697.  https://doi.org/10.26423/rctu.v4i3.278.

For anthropogenic carbon dioxide (CO2) capture is important to consider: gas storage’s formation capacity, saturation and pressure plume size after injection; including the risks associated with CO2 leakage and faults reactivation. A formation with a reasonable pore volume would be a good candidate for CO2 storage, however, not all high porosity formations have the ability to store large amounts of gas over a long period of time. That's the biggest concern when it refers to CO2 capture. Saturation and pressure plume size during CO2 injection as well as site monitoring after injection were simulated in this research, using CRD field reservoir models. The application of Pareto diagrams and surface responses allowed us to determine the most important parameters that affected the saturation and pressure plume, quantifying the correlation between different parameters of adjusted and dimensioned historical models.
