(1) | q_L = frac{q_t}{} B_w Y_w +[ (B_o - R_s B_g] + B_g (GOR-R_s)] (1-Y_w) |
where
q_w, \, q_o, \, q_g | water, oil and gas sandface flowrates |
q_W, \, q_O, \, q_G | water, crude oil and natural gas surface flowrates |
B_w, \, B_o, \, B_g | formation volume factors between separator and sandface pressure/temperature conditions |
R_s, \, R_v | Solution GOR and Vaporized oil ratio at sandface pressure/temperature conditions |
\displaystyle Y_w = \frac{q_W}{q_L} | Production Water Cut |
---|---|
\displaystyle GOR= \frac{q_G}{q_O} | Production Gas-Oil-Ratio |
