Cuttings produced per foot of hole drilled - lbs

Input(s)

$\mathrm{C}_{\mathrm{a}}$: Capacity of Hole $(\mathrm{bbl} / \mathrm{ft})$

$\mathrm{L}_{\mathrm{d}}$: Footage Drilled (ft)

SG: Specific Gravity of Cuttings (fraction)

Ø: Porosity (fraction)

Output(s)

$\mathrm{W}_{\mathrm{cg}}$: Amount of Cuttings Produced per each Foot of Hole Drilled (lb)

Formula(s)

$$ \mathrm{W}_{\mathrm{cg}}=350 *\left(\mathrm{C}_{\mathrm{a}}\right) *\left(\mathrm{~L}_{\mathrm{d}}\right) *(1-\varnothing) * \mathrm{SG} $$
