Carbon Storage Potential of North American Oil & Gas Produced Water Injection with Surface Dissolution

Carbon dioxide (CO2) geological storage traditionally involves capturing a CO2 stream from point source such as power station or cement, steel, natural gas processing plant, transporting it and compressing it, prior to injection supercritical phase into suitable reservoir overlain by cap-rock seal. One of the main perceived risks in is migration leakage buoyant through seal, via faults fractures, other out complex. Injection dissolved water may be one solution mitigate risk. This approach could take advantage large volumes wastewater already being reinjected saline aquifers worldwide but particularly North America, thus reducing costs. study examines potential “piggyback” off existing industry novel carbon option.
