How to Calculate and Solve for Total Oil Pore Volume of Reservoir Fluid Flow

The image above represents the total oil pore volume. To calculate the total oil pore volume, four essential parameters are needed, and these parameters are initial oil FVF (Boi), initial water saturation (Swi), oil in place (N), and gas cap ratio (m).

The formula for calculating the total oil pore volume:

(PV)o = NBoi(1 + m) / 1 + Swi

Where;

(PV)o = Total Oil Pore Volume
Boi = Initial Oil FVF
Swi = Initial Water Saturation
N = Oil in Place
m = Gas Cap Ratio

Let’s solve an example;
Find the total oil pore volume when the initial oil FVF is 9, the initial water saturation is 11, the oil in place is 21 and the gas cap ratio is 18.

This implies that;

Boi = Initial Oil FVF = 9
Swi = Initial Water Saturation = 11
N = Oil in Place = 21
m = Gas Cap Ratio = 18

That is, (PV)o = NBoi(1 + m) / 1 + Swi
(PV)o = 21 x 9(1 + 18) / 1 + 11
So, (PV)o = 3591 / -10
(PV)o = -359.1

Therefore, the total oil pore volume is -359.1
