Perforation penetration ratio (formation of interest/reference formation)
Input(s)
\(c_{r}\): Compressive Strength of reference Formation (ksi)
\(c\) : Compressive Strength of Formation of Interest (ksi)
Output(s)
\(L_{p}\): Total Target Penetration in Formation of Interest (in.)
\(L_{p r}\): Total Target Penetration in Reference Formation (in.)
Formula(s)
\[
\frac{L_{p}}{L_{p r}}=\exp \left[0.086\left(c_{r}-c .\right]\right.
\]
