Damaged to Undamaged Productivity Ratio - Acidizing Calculator

JsJo=Fkln⁡(re/rw)ln⁡(rs/rw)+Fkln⁡(re/rs)\frac{J_s}{J_o}=\frac{F_k\ln(r_e/r_w)}{\ln(r_s/r_w)+F_k\ln(r_e/r_s)}

Enter the required inputs, confirm the units, and run the calculator to solve J_ratio. Review the formula source and assumptions before using the result in engineering work.
