Rate of gas portion that enters the mud

Input(s)

$q_{r}$: Rock Removal Rate $(\mathrm{SCF} / \mathrm{min})$

$S_{g}$: Gas Saturation (fraction)

Ø: Formation Porosity (per cent)

Output(s)

$q_{g}$: The Rate of Gas Portion that enters the Mud with Bulk Rock (SCF/min)

Formula(s)

$$ q_{g}=q_{r} \varnothing S_{g} $$
