q | total subsurface flowrate of the well |
---|---|
J | total well productivity Index |
p_e | apparanet formation pressure of dual-layer formation |
q_1 | total subsurface flowrate of the Layer #1 |
p_1 | formation pressure of the Layer #1 |
J_1 | productivity Index of the Layer #1 |
q_2 | total subsurface flowrate of the Layer #2 |
p_2 | formation pressure of the Layer #2 |
J_2 | productivity Index of the Layer #2 |
h | true vertical height between the layers tops |
The above equations are valid for both producers and injectors.
