In the past 30 years, although CO 2-equivalent emissions from methane and process emissions have occasionally declined slightly, they have also shown an overall increasing trend until 2021 2-equivalent emissions from methane and process emissions reach 4,784.24 million tonnes in 2021, which is about double its total value in 1990.The total CO 2 emissions

Feasibility of Advanced CO2 Injection and Well Pattern

Global tight-oil reserves are abundant, but the depletion development of numerous tight-oil reservoirs remains unsatisfactory. CO2 injection development represents a significant method of reservoir production, potentially facilitating enhanced oil recovery (EOR) alongside CO2 storage. Currently, limited research exists on advanced CO2 injection and well

Evaluation of CO2 enhanced oil recovery and CO2 storage

The oilfield has great potential for CO 2 storage and EOR in Changqing. He et al. evaluated reservoirs within a 300 km radius of Yulin City. Of the 17 reservoirs evaluated, 9 are suitable for CO 2 immiscible flooding and 8 are suitable for CO 2 miscible flooding.
