Oil Reserves

Where:
• Nf= volumetric recoverable oil reserves in stock-tank barrels (STB)
• 7758= barrels per acre-foot
• A= drainage area in acres
• h= reservoir thickness in feet
• ɸ= porosity (decimal fraction)
• Sh= hydrocarbon saturation (1-Sw) (decimal fraction)
• RF= recovery factor
• Boi= oil volume factor, or reservoir barrels per stock-tank barrel

Calculate Volumetric Producible Oil Reserves (Nf)
A: Acres		h: ft
ɸ: Decimal		Sh: Decimal
FR: Decimal		Boi: Bbls/STB

Oil Volume Factor (Boi)

Where:
• Boi= oil volume factor, or reservoir barrels per stock-tank barrel
• GOR= gas-oil ratio

Calculate Oil Volume Factor (Boi)- GOR
GOR: SCF / STB

Gas-Oil Ratio (GOR)

GOR (Oil-Gas Ratio) = (Gas in cubic feet) / (Oil in barrels)

Calculate Gas-Oil Ratio (GOR)
Gas: cubic ft		Oil: Bbls
