Hydrocarbon Mixture and CO2 Adsorptions in A Nanopore-Bulk Multiscale System in Relation to CO2 Enhanced Shale Gas Recovery
Download2021-07-01
Thanks to the continuous depletion of conventional gas reservoirs, shale gas plays an important role to meet the global natural gas demand. The CO2 'huff-n-puff' process has been proven to be an effective method to enhance shale gas recovery and sequestrate CO2. Unlike conventional reservoirs,...

Molecular Dynamics Study on CO2 Storage in Water-Filled Kerogen Nanopores in Shale Reservoirs: Effects of Kerogen Maturity and Pore Size
Download2020-12-21
Li, Wenhui, Zhang, Mingshan, Nan, Yiling, Pang, Wanying, Jin, Zhehui
CO2 sequestration in shale reservoirs is an economically viable option to alleviate carbon emission. Kerogen, a major component in the organic matter in shale, is associated with a large number of nanopores, which might be filled with water. However, the CO2 storage mechanism and capacity in...
