Depleted gas reservoirs are important potential sites for CO2 geological sequestration due to their proven integrity and safety, well-known geological characteristics, and existing infrastructures and wells built for natural gas production.
The Sichuan Basin has a large number of gas fields in which approximately 5.89×109 tons of CO2 can be stored.
The Huangcaoxia gas field has the best opportunity in the eastern Sichuan Basin for a pilot project of CO2 sequestration due to its relatively large storage capacity and the nearly depleted state.
A coupled thermal-hydrodynamic model including faults is built based on the geological and hydrogeological conditions in the Huangcaoxia gas field.
The results of the numerical simulations show that the downhole temperature is above 80°C at a downhole pressure of 14 MPa under the constraint of temperature drop in the reservoir due to the strong Joule-Thomson effect.
The corresponding injection pressure and temperature at the wellhead are 10.5 MPa and 60°C, respectively.
The sizes of the pressure and CO2 plumes after an injection of 10 years are 18 km and 5 km, respectively.
The zone affected by temperature change is very small, being about 1-2 km away from the injection well.
The injection rate in the injection well Cao 31 averages 6.89 kg/s (21.73×104 tons/a).
For a commercial-scale injection, another four wells (Cao 9, Cao 30, Cao 6, and Cao 22) can be combined with the Cao 31 well for injection, approaching an injection rate of 35 kg/s (1.10×106 tons/a).
Both the pressure and temperature of CO2 injection decrease with the increasing depleted pressure in the gas reservoir when the latter is below 6 MPa.
With the technique of CO2-enhanced gas recovery (CO2-EGR), the CO2 injection rate is improved and approximately 1.58×107 kg of gas can be produced during a studied time period of 10 years.
