Volumetric value of current (remaining) Hydrocarbon In Place (HCIP) recalculated to NTP conditions and represented by two numbers: { Stock-Tank Oil In-Place (STOIP) , Stock-Tank Gas In-Place (STGIP) }
Before the anthropogenic invasion the current and initial volumes of Petroleum Hydrocarbons are the same: STHCIP = STHCIIP
