... Abstract Salt caverns are utilized widely as natural gas storage and compressed air energy storage because of rheology and low-permeability of salt. For both natural gas storage or energy storage, gas injection and gas withdrawal are carried on alternately, two cycles one year for natural gas...

... Abstract This paper mainly focuses on how to improve exploitation rate of coal bed methane (CBM) was presented in the paper. To enhance efficiency of exploitation of coal bed methane, the carbon dioxide or nitrogen gases were injected in the coal bed in the experiments. The injection...

... Abstract This paper presents a study of heterogeneous caprock fracturing processes during underground CO 2 injection into a brine aquifer. We simulate CO 2 injection and fracturing using a combination of theTOUGH2 multiphase flow simulator and the RDCA rock discontinuous cellular automaton...

... Abstract In geological sequestration, CO 2 is injected under high pressure into deep underground rock formations, including deep saline aquifers. This paper presents the invading supercritical CO 2 -brine two-phase numerical model to describe CO 2 flow and transport processes in deep saline...
