Abstract

A depleted gas and gas condensate reservoir can store significantly more gas than a depleted oil reservoir with identical HCPV due to the fact that gas is more compressible than oil and the ultimate gas recovery in reservoir is typically higher than that of oil reservoirs. Also geologic CO 2 storage in retrograde gas reservoirs can re-vaporize condensates and thus re-pressurized the reservoir which consequently leads to greater liquid condensate recovery. A material balance equation for CO 2 sequestration in gas reservoirs was developed to predict CO 2 sequestration volume and survey CO 2 sequestration operations during injection. Implications of dry, wet, and retrograde gas reservoirs on the P/Z plot usage are presented.
