This study examines the impact of different CO 2 injection methods on coalbed methane recovery. Specifically, this study investigated the effectiveness of continuously injecting CO 2 versus injecting CO 2 that had been soaked for two weeks. The objective was to ascertain which approach was more successful in enhancing CO 2 Enhanced coalbed Methane (CO 2 -ECBM). The experiment involved injecting 3 MPa of CH 4 into dry coal samples, allowing it to adsorb until reaching equilibrium, and then injecting 5 MPa of CO 2 to recover adsorbed CH 4 . The continuous method recovered CH 4 without detectable effluent concentration for 5 hours, but desorption efficiency was only 26% due to fast flow. On the other hand, the desorption efficiency of the cyclic method was only 12%, indicating trapped CH 4 . A comparison of desorption efficiency per unit of time shows the continuous method is more effective than the cyclic method. The results of this study demonstrate the continuous method is more effective for the desorption of CH 4 , and its efficiency can be improved by briefly soaking CO 2 on coal and then reinjecting it to maximize CH 4 recovery. It is advisable to limit the soaking time to prevent excessive swelling of the coal matrix, which can hinder seam flow and harm long-term gas production.

Selecting Geological Formations for CO2 Storage: A Comparative Rating System

Underground storage of carbon dioxide (CO2) in geological formations plays a vital role in carbon capture and storage (CCS) technology. It involves capturing CO2 emissions from industrial processes and power generation and storing them underground, thereby reducing greenhouse gas emissions and curbing the impact of climate change. This review paper features a comparative analysis of CO2 storage in deep saline aquifers, depleted reservoirs, coal seams, basaltic formations and clastic formations. The comparison has been drawn based upon seven factors carefully selected from the literature, i.e., safety, storage capacity, injection rates, efficiency, residual trapping, containment and integrity and potential to improve, and all of these factors have been rated from low (1) to high (5) based upon their individual traits. Based upon these factors, an overall M.H. rating system has been developed to categorize geological formations for CO2 storage and it is observed that deep water aquifers and basaltic formations are the most effective options for CO2 storage. Lastly, a detailed way forward has been suggested, which can help researchers and policymakers to find more viable ways to enhance the efficiency of CO2 storage in various geological formations.
