Part of total current Hydrocarbon In Place (HCIP) in petroleum reservoir which can be economically recovered to the surface under specific FDP.
...
The percentage which recoverable reserves STHCR constitute of the total the current STHCIP is called Estimated Ultimate Recovery.
Unlike Hydrocarbon Surface Tank Hydrocarbon Initial In Place (STHCIIP) is called Recovery Factor.Unlike STHCIIP, which is purely geological concept, the STHCR and corresponding RF depend on the parameters of FDP based on reserves HCIP), which is a geological category, the Hydrocarbon Reserves depend on the parameters of FDP based on petroleum reservoir, complexity, recovery method, recovery duration, surface logistics and economics.
There are different ways of classifying the hydrocarbon reserves based on their volume and structure.
