Total produced Produced or injected flowrate of all fluids of water across the well-reservoir contact with the volumes measured at the sandface temperature and pressure conditions.
For MBO fluid @model the total sandface flowrate Usually abbreviated as
or is related to surface flowrates of water .For the volatile oil fluid model the total sandface flowrate is related to surface flowrates of fluid components as as (see derivation):| LaTeX Math Block |
|---|
|
q_tw = B_w \, q_W + \frac{B_o - R_v B_g}{1 - R_v R_s} \, q_O + \frac{B_g - R_s B_o}{1 - R_v R_s} \, q_G
|
where
| water, oil, gas surface flowrates | | LaTeX Math Inline |
|---|
body | \{ \{ q_W, \, q_O, \, q_G \} | , \, B_o, \, B_g \} | Solution GOR and Vaporized oil ratio at sandface pressure/temperature conditions |
It simplifies for the Black Oil model to:
| LaTeX Math Block |
|---|
|
q_t = B_w \, q_W + B_o \, q_O + (B_g - R_s B_o) \, q_G
|
and simplifies further down to production from undersaturated reservoir as:
| LaTeX Math Block |
|---|
|
q_t = B_w \, q_W + B_o \, q_O
|
and even simpler for single-phase fluid with surface flow rate
and formation volume factor B:| LaTeX Math Block |
|---|
|
q_t = q \cdot B
