Undersaturated Gas Solubility Rs(p) @model

Created by Arthur Aslanyan (Nafta College), last modified on Jan 16, 2022

The undersaturated gas solubility R_s stays constant for all pressures above bubble point pressure:

Undersaturated gas solubility R_s, p ≥ pb	scf/stb	$\begin{array}{l}\displaystyle R_s(p, T) = R_{sb}(T)\end{array}$

where

$\begin{array}{l}p\end{array}$	psia	Fluid pressure
$\begin{array}{l}T\end{array}$	°F	Initial formation temperature
$\begin{array}{l}R_{sb}\end{array}$	scf/stb	Gas Solubility at bubble point pressure p = p_b
