Perforation hole size (perforation)
Input(s)
\(x\): Brinell Hardness of Casing of Interest (dimensionless)
\(d_{r}\): Entrance Hole Diameter in Reference Casing (in.)
\(x_{r}\): Brinell Hardness of Reference Casing (dimensionless)
Output(s)
d: Entrance Hole Diameter in Casing of Interest (in.)
Formula(s)
\[
d=\left(\frac{\left[2,250+4.2 x_{r}\right]}{[2,250+4.2 x]}\right)^{0.5} d_{r}
\]
