Preliminary Numerical Modeling of CO₂ Geological Storage in the Huangcaoxia Gas Reservoir in the Eastern Sichuan Basin, China

Table 2

Hydrogeological properties of the reservoir.

Reservoir		OGIP (10^8 m^3)	(MPa)	(°C)		(MPa)	(°C)		(kg/m^3)	(10^4 ton)
Jia-2^1/Jia-1	0.9	20.93	0.101	20	0.998	14.12	43	0.843	698.7	860
Jia-2^2	0.9	33.84	0.101	20	0.998	13.83	40	0.834	720.3	1430
Total	2290

Note: the CO₂ storage capacity is calculated by [23], where is the density of CO₂ at the reservoir conditions. is the recovery factor and set to be 0.9. is the fraction of injected gas and equal to 0. , , and are the pressure, temperature, and gas compressibility factor, respectively. The subscripts and denote, in this order, the reservoir and surface conditions. The values of the parameters contained in Table 2 are calculated from GasEOS (http://esdtools.lbl.gov/gaseos/ [24]).
