Abstract
Experimental setup for CO2 injection for Enhance Shale Gas Recovery (ESGR) - A Review
Highlights
Anthropogenic carbon dioxide release in the environment due to burning fossil fuel which has resulted in global warming that’s why environmentalists are facing major issues about increasing atmospheric temperature and pollution level
According to the Energy Information Administration(EIA) shale gas holds a large proportion of unconventional energy sources in the earth as the estimation of technically producible shale gas is 6,622 TCF(Trillion Cubic Feet)
This paper review published information on experimental data explaining enhanced methane recovery with injection of carbon dioxide and nitrogen gases
Summary
Anthropogenic carbon dioxide release in the environment due to burning fossil fuel which has resulted in global warming that’s why environmentalists are facing major issues about increasing atmospheric temperature and pollution level. If the method includes CO2 injection for production it can result in storing around 26,114GT of CO2 in subsurface as used for pressure maintenance or for producing natural gas as Enhance Shale Gas Recovery(ESGR) method. Allover estimating gas flow capacity through shale by Langmuir heterogeneous adsorption isotherm, Simplified local-density (SLD) to calculate CO2 adsorption on shale, Equation of State (EOS)[6], Elliott-Suresh-Donohue (ESD)[6], Brunauer–Emmett–Teller (BET) isotherm[7], Gibbs Free Adsorption process equations, LF NMR(low-field nuclear magnetic resonance) and operating systems is used to calculate adsorption rate and process on the different type of shale. Pressurized gas cylinders(CO2,N2,CH4) attached to the infusion syringe pump These pumps play a major role and are a crucial component in production and estimation of gas samples from shale when using supercritical fluids such as carbon dioxide. Computer setup installed with relative software such as LF NMR(Huang, Xue & Li, 2020)
