Average Per-well Rate

The averaging method of flow rate, which shows a work of one average well in group of wells.

Average per-well rate are calculated by formula

(1)	$\begin{array}{l}\displaystyle < q_i>_1 =\frac{q_i}{N}\end{array}$

where

$\begin{array}{l}\mathrm{< q_i>_1}\end{array}$	per-well rate
$\begin{array}{l}\mathrm{q_i}\end{array}$	rate (production or injection)
$\begin{array}{l}\mathrm{N}\end{array}$	total number of wells (producers or injectors)
$\begin{array}{l}\mathrm{i}\end{array}$	index, which points to the type of fluid or gas (see table below)

Depending on index, the rate $\begin{array}{l}\mathrm{q_i}\end{array}$ may mean:

Index	Symbol	Rate
$\begin{array}{l}\mathrm{i=O}\end{array}$	$\begin{array}{l}\mathrm{q^{\uparrow}_O}\end{array}$	Oil production rate
$\begin{array}{l}\mathrm{i=L}\end{array}$	$\begin{array}{l}\mathrm{q^{\uparrow}_L}\end{array}$	Liquid production rate
$\begin{array}{l}\mathrm{i=W}\end{array}$ (with $\begin{array}{l}\mathrm{\uparrow}\end{array}$ )	$\begin{array}{l}\mathrm{q^{\uparrow}_W}\end{array}$	Water production rate
$\begin{array}{l}\mathrm{i=G}\end{array}$ (with $\begin{array}{l}\mathrm{\uparrow}\end{array}$ )	$\begin{array}{l}\mathrm{q^{\uparrow}_G}\end{array}$	Gas production rate
$\begin{array}{l}\mathrm{i=t}\end{array}$	$\begin{array}{l}\mathrm{q^{\uparrow}_t}\end{array}$	Total sandface flowrate
$\begin{array}{l}\mathrm{i=W}\end{array}$ (with $\begin{array}{l}\mathrm{\downarrow}\end{array}$ )	$\begin{array}{l}\mathrm{q^{\downarrow}_W}\end{array}$	Water injection rate
$\begin{array}{l}\mathrm{i=G}\end{array}$ (with $\begin{array}{l}\mathrm{\downarrow}\end{array}$ )	$\begin{array}{l}\mathrm{q^{\downarrow}_G}\end{array}$	Gas injection rate
