Fig. 1. Dual-layer well schematic

q = q_1 + q_2

p_{wf} = p_e - q/J

J = J_1 + J_2

p_e = \frac{J_1 \cdot p_1 + J_2 \cdot p_2}{J_1 + J_2}

where

	total subsurface flowrate of the well
	total well productivity Index
	apparanet formation pressure of dual-layer formation
	total subsurface flowrate of the Layer #1
	formation pressure of the Layer #1

The above equations are valid for both producers and injectors.
