Total Sandface Productivity Index (Jt)

Created by Arthur Aslanyan (Nafta College), last modified on Nov 30, 2019

Productivity Index based on all fluids across the well-reservoir contact:

(1)	$\begin{array}{l}\displaystyle J_t = \frac{q_t}{p_e-p_{wf}}\end{array}$

where

$\begin{array}{l}q_t\end{array}$	total sandface flowrate
$\begin{array}{l}p_e\end{array}$	multiphase formation pressure
$\begin{array}{l}p_{wf}\end{array}$	sandface bottom hole pressure
