Average gas solubility

Input(s)

$s_{1}$: Solubility at $p_{1}(\mathrm{SCF} / \mathrm{STB})$

$s_{2}$: Solubility at $p_{2}(\mathrm{SCF} / \mathrm{STB})$

$p_{1}$: Pressure 1 (psi)

$p_{2}$: Pressure $2(\mathrm{psi})$

Output(s)

$S_{\text {avg }}$: Average Gas Solubility (SCF/STB/psi)

Formula(s)

$$ \mathrm{S}_{\mathrm{avg}}=\frac{\mathrm{s}_{1}-\mathrm{s}_{2}}{\mathrm{p}_{1}-\mathrm{p}_{2}} $$
