Perforation length in formation

Input(s)

$L_{p r}$: Total Target Penetration in Reference Target (in.)

$d_{w b}$ : Wellbore Diameter (in.)

$d_{c i}$ : Casing Inner Diameter (in.)

Output(s)

$L_{p}$: Total Target Penetration in Formation of Interest (in.)

Formula(s)

$$ L_{p}=\left(L_{p c}\right)-0.5\left(d_{w b}-d_{c i}\right) $$
