Hydrocarbon Pore Volume Occupied by Gas Cap
Hydrocarbon pore volume (HCPV) occupied by the gas cap is the volume of the reservoir's pore space that is filled with gas in a gas cap, as opposed to oil or water. This measurement is important in reservoir engineering as it helps in understanding the distribution of fluids within the reservoir and in estimating recoverable hydrocarbons.
