\displaystyle
q_O = q_{Oo} + q_{Og}
\displaystyle
q_G = q_{Gg} + q_{Go}
\displaystyle
q_W = q_{Ww} |
Following the definition of Solution GOR (Rs) and Vaporized Oil Ratio (Rv) :
|
\displaystyle
R_s = q_{Go}/q_{Oo}
\displaystyle
R_v = q_{Og}/q_{Gg} |
so that:
(3) |
q_O = q_{Oo} + R_v \, q_{Gg} |
|
(4) |
q_G = q_{Gg} + R_s \, q_{Oo} |
| |
Following the definition of Oil formation volume factor (Bo) , Gas formation volume factor (Bg) and Water formation volume factor (Bw):
(6) |
q_{Oo}= \frac{q_o}{B_o} |
|
(7) |
q_{Gg} = \frac{q_g}{B_g} |
|
(8) |
q_{Ww} = \frac{q_w}{B_w} |
|
so that:
(9) |
q_O = \frac{q_o}{B_o} + R_v \,\frac{q_g}{B_g} |
|
(10) |
q_G = \frac{q_g}{B_g} + R_s \, \frac{q_o}{B_o} |
|
(11) |
q_W = \frac{q_w}{B_w} |
|
and solving the above system of equations leads to:
(12) |
q_o = \frac{B_o \cdot (q_O - R_v \, q_G)}{1- R_v \, R_s} |
|
(13) |
q_o = \frac{B_o \cdot (q_G - R_s \, q_O)}{1- R_v \, R_s} |
