Use this simple drilling calculator to calculate STOIIP - stock tank oil initially in place using area, reservoir thickness, rock porosity, connate water saturation, oil formation volume factor values.

Stock Tank Oil Initially in Place (STOIIP) Calculator

Formula:

STOIIP = 7758×A×h×ɸ(1-Swc)Boi

Where,

A = area

h = reservoir thickness

ɸ = rock porosity

Swc = connate water saturation

Boi = oil formation volume factor
