(352d) Implications for Developing Multiple CCS Projects in Same Geological Setting – US Gulf Coast Case Study

CO2 injection into geological formations will increase the local and regional pressure. Currently many projects have been planned and developed across USA and all those projects looking for best geological formations close to major sources of CO2 trying to reduce the pipeline length and cost. Many of the proposed projects end up being in very close proximity to each other. Texas and Louisiana Gulf Coast is one of those major targets for CCS that has this specific feature. We have developed analytical models that closely model two-phase flow behavior of the CO2 injection into porous media and allows for fast analysis of interference among multiple CCS projects. Our results show that interreference among projects is likely and it can potentially hinder project implementations both from technical point of view and legal challenges for the CCS community.
