STOIIP stands for stock tank oil initially in place. Equals to the volume of the reservoir oil at the surface conditions.

STOIIP = \frac{HCPV}{B_o} = \frac{A * h * \phi * S_o}{B_o}

where

A

= Area, m2

B_o

= Oil formation volume factor, m2

h

= Net pay, oil saturated thickness, m

HCPV

= Hydrocarbon pore volume, m3

\phi

= Porosity, fraction

S_o

= Oil saturation, fraction

STOIIP

= Stock tank oil initially in place, m3
