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

Stock Tank Original Oil in Place (STOOIP) Calculator

Formula:

STOOIP = 7758 x ORA x NPT x P x OSa x OSh

Where,

ORA = Oil Reservoir Area

NPT = Average Net Pay Thickness

P = Porosity

OSa = Oil Saturation

OSh = Oil Shrinkage
