📐 Calculation Formulas
STOIIP (Stock Tank Oil Initially In Place):
STOIIP = Area × Net Thickness × N/G × Porosity × (1 - Sw) / Bo
Result in million stock tank barrels (MMstb)
STOIIP = Area × Net Thickness × N/G × Porosity × (1 - Sw) / Bo
Result in million stock tank barrels (MMstb)
Recoverable Oil (Primary):
Recoverable Oil = STOIIP × Primary Recovery Factor
Result in million stock tank barrels (MMstb)
Recoverable Oil = STOIIP × Primary Recovery Factor
Result in million stock tank barrels (MMstb)
Ultimate Recovery (Enhanced):
Ultimate Recovery = STOIIP × Enhanced Recovery Factor
Result in million stock tank barrels (MMstb)
Ultimate Recovery = STOIIP × Enhanced Recovery Factor
Result in million stock tank barrels (MMstb)
