Refers to Petroleum Hydrocarbon initially present in Petroleum Reservoir before the anthropogenic invasion.
It consists of OIIP and GIIP.
The volumetric value of Total volume of total hydrocarbon reserves recalculated to NTP conditions:
Hydrocarbon Initial In Place (HCIIP) in NTP conditions is given by STHCIIP :
STHCIIP = HCIIP = STOIIP + STGIIP
