“…Natural gas will play a key role in hydrogen production [3]. These advantages make natural gas a promising candidate to replace liquid fossil fuels and coal, and to be a transition fuel until renewable energy sources are feasible on a large scale [4,5]. It is well known that about 40% of the remaining natural gas sources have a CO 2 concentration higher than 2% and a H 2 S concentration higher than 100 ppm [6].…”

Review on the Mechanism of CO2 Storage and Enhanced Gas Recovery in Carbonate Sour Gas Reservoir

Carbonate gas reservoirs in the Sichuan Basin have many complex characteristics, such as wide distribution, strong heterogeneity, high temperature, high pressure, high H2S and CO2 content and an active edge or bottom water. In the late stage of exploitation of carbonate sour gas reservoirs, the underground depleted reservoirs can provide a broad and favorable space for CO2 storage. If CO2 is injected into the depleted carbonate sour reservoirs for storage, it will help to achieve the goal of carbon neutrality, and the CO2 stored underground can perform as “cushion gas” to prevent the advance of edge or bottom water, to achieve the purpose of enhanced natural gas recovery. Injecting CO2 into low permeability reservoirs for oil displacement has become an important means to enhance oil recovery (EOR). However, the mechanism of EOR by injecting CO2 into carbonate sour gas reservoirs is not clear and the related fundamental research and field application technology are still in the exploration stage. This paper reviews the main scientific and technical perspectives in the process of injecting CO2 into carbonate sour gas reservoirs for storage and enhancing gas recovery.

“…A few studies of the phase equilibria of the (CO 2 + CH 4 + H 2 S) ternary system have been reported [3,4,[42][43][44], although none of these address the high dilution behavior of H 2 S and so only limited comparisons are possible. Hensel et al [4]…”

“…Phase compositions were not analyzed. Recently, Theveneau et al[44] reported VLE measurements with full composition analysis for two different global compositions at temperatures between (243.50 and 333.13) K and pressures up to 11.24 MPa. However, in their study, x 3 varied between 0.427 and 0.986 and so comparisons are not meaningful.…”

Vapor-liquid equilibrium (VLE) measurements of the (CO2 + CH4) system are reported along seven isotherms at temperatures varying from just above the triple point to just below the critical point of CO2 at pressures from the vapor pressure of pure CO2 to approximately 9 MPa, including near-critical states. From these data, the critical locus has been determined and correlated over its entire length. The VLE data are correlated with the Peng-Robinson equation of state (PR-EoS), using a temperature-dependent binary interaction parameter, and also compared with the predictions of the GERG-2008 equation of state. The former represents the phase compositions across all isotherms with a root-mean-square molefraction deviation of S = 0.0075 while, for the latter, S = 0.0126. Measurements of the three-phase solidvapor-liquid equilibrium (SVLE) line are reported at temperatures from approximately (204 to 216) K and a new correlation is developed which is valid from 145 K to the triple point of CO2. Additionally, we report the partitioning of trace levels of H2S between coexisting liquid and vapor phases of the (CO2 + CH4) system and compare the results with the predictions of the PR-EoS.
