TL;DR: In this article, a microseismic monitoring program has been implemented to map the CO 2 flow anisotropy and estimate its sweeping efficiency, and the temporal change of produced CO 2 has been analyzed in realtime mode to monitor the dynamic response in production wells.

TL;DR: In this article, a large-scale demonstration project on CO 2 EOR and storage in China has been conducted, and nearly 0.26 million ton of CO 2 (0.32 Hydrocarbon Pore Volume) has been injected under a miscible or near-miscible flooding mode with CO 2 utilization efficiency of 6.3 MScf/bbl and an expected enhanced oil recovery of over 10% would be achieved.

TL;DR: Wang et al. as mentioned in this paper used wellbore integrity detecting, produced fluid sampling, CO2 gas tracer, electric spontaneous potential measurement, micro-seismic and cross-well seismic.

TL;DR: In this article, a mechanistic model of CO2 foam that allows for direct simulation of foam generation, propagation, coalescence and collapse was described, and a three dimensional heterogeneous conceptual reservoir model was then built to study the mechanisms of CO 2 foam flooding based on the foam model.

TL;DR: In this article, a novel foaming method for reducing CO2 mobility and blocking gas channeling is proposed, which is based on a CO2-sensitive chemical (compound with amine group) to generate foams or thicken the injected water in situ.
