Giger-Karcher Horizontal Well Critical Rate Calculator

qc=khh2gΔρBμL[1−16(hL)2]q_c=\frac{k_hh^2g\Delta\rho}{B\mu L}\left[1-\frac{1}{6}\left(\frac{h}{L}\right)^2\right]

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