How to Calculate and Solve for Cumulative GOR of Reservoir Fluid Flow | The Calculator Encyclopedia

The image above represents the cumulative GOR. To calculate the cumulative GOR, two essential parameters are needed: cumulative gas production (G_p) and cumulative oil production (N_p).

The formula for calculating the cumulative GOR:

R_p = ^G_p / _Np

Where;

R_p = Cumulative GOR
G_p = Cumulative Gas Production
N_p = Cumulative Oil Production

Let’s solve an example;
Find the cumulative GOR with a cumulative gas production of 32 and a cumulative oil production of 44.

This implies that;

G_p = Cumulative Gas Production = 32
N_p = Cumulative Oil Production = 44

R_p = ^G_p / _Np
That is, R_p = ³² / ₄₄
R_p = 0.72

Therefore, the cumulative GOR is 0.72.

Calculating the Cumulative Gas Production when the Cumulative GOR and the Cumulative Oil Production are Given

G_p = R_p x N_p

Where;

G_p = Cumulative Gas Production
R_p = Cumulative GOR
N_p = Cumulative Oil Production

Let’s solve an example;
Find the cumulative gas production when the cumulative GOR is 56 and the cumulative oil production is 19.

This implies that;

R_p = Cumulative GOR = 56
N_p = Cumulative Oil Production = 19

So, G_p = R_p x N_p
G_p = 56 x 19
G_p = 1064

Therefore, the cumulative gas production is 1064.

Calculating the Cumulative Oil Production when the Cumulative GOR and the Cumulative Gas Production are Given

N_p = ^G_p / _Rp

Where;

N_p = Cumulative Oil Production
R_p = Cumulative GOR
G_p = Cumulative Gas Production

Let’s solve an example;
Find the cumulative oil production when the cumulative GOR is 18 and the cumulative gas production is 72.

This implies that;

R_p = Cumulative GOR = 18
G_p = Cumulative Gas Production = 72

So, N_p = ^G_p / _Rp
N_p = ⁷² / ₁₈
N_p = 4

Therefore, the cumulative oil production is 4.
