STOIIP
STOIIP stands for stock tank oil initially in place. Equals to the volume of the reservoir oil at the surface conditions.
Equation
where
= Area, m2
= Oil formation volume factor, m2
= Net pay, oil saturated thickness, m
= Hydrocarbon pore volume, m3
= Porosity, fraction
= Oil saturation, fraction
= Stock tank oil initially in place, m3
