Research and Development of a Permanent OBC System for Time-lapse Seismic Survey and Microseismic Monitoring at the Offshore CO2 Storage Sites

Leakage Mitigation During CO2 Geological Storage Process Using CO2 Triggered Gelation

“…Frequently time-lapse seismic surveys have been widely applied to monitor CO 2 migrations during the sequestration. 17,18 From the viewpoints of geological trapping mechanisms, injecting CO 2 into depleted oil and gas should be relatively safer than other structures with demonstrated seal performance for trapping oil and gas over long geologic time. CO 2 storage using deep saline aquifer has great potential with competitive storage capacity and wide distributions.…”

“…analysis of leakage risk, monitoring method and leakage blocking technology, have been paid more and more attentions during the demonstration projects of CO 2 storage. , In field-scale CO 2 sequestration, monitoring of the CO 2 leakage is required before taking approaches to block the leakage. Frequently time-lapse seismic surveys have been widely applied to monitor CO 2 migrations during the sequestration. , From the viewpoints of geological trapping mechanisms, injecting CO 2 into depleted oil and gas should be relatively safer than other structures with demonstrated seal performance for trapping oil and gas over long geologic time.
