Volumetric flowrate of the fluid phase across the well-reservoir contact
In most popular practical case of a 3-phase fluid model this will be:
In case of Volatile Oil Reservoir the connection with surface flowrates and mass flowrates will be:
(1) |
q_o = \frac{ B_o \cdot ( q_O - R_v \, q_G) }{1- R_v \, R_s} |
|
(2) |
q_O = \frac{m_O}{\rho_O} |
|
(3) |
q_g = \frac{ B_g \cdot ( q_G - R_s \, q_O)}{1- R_v \, R_s} |
|
(4) |
q_G = \frac{m_G}{\rho_G} |
|
|
(6) |
q_W = \frac{m_W}{\rho_W} |
|
(7) |
q_t = q_o + q_g + q_w |
|
(8) |
q_t = \frac{B_o - B_g \, R_v}{1-R_v \, R_s} \cdot q_O
+\frac{B_g - B_o \, R_v}{1-R_v \, R_s} \cdot q_G
+ B_w \cdot q_W |
|
(9) |
q_t = \frac{B_o - B_g \, R_v}{(1-R_v \, R_s) \rho_O} \cdot m_O
+\frac{B_g - B_o \, R_v}{(1-R_v \, R_s) \, \rho_G} \cdot m_G
+ \frac{B_w}{\rho_W} \cdot m_W
|
|
(10) |
\rho_t = (\dot m_O + \dot m_G + \dot m_G)/q_t |
