Skin Factor for a Deviated Well Calculator

sθ=−(θw41)2.06−(θw56)1.865log⁡10(hd100)s_\theta=-\left(\frac{\theta_w}{41}\right)^{2.06}-\left(\frac{\theta_w}{56}\right)^{1.865}\log_{10}\left(\frac{h_d}{100}\right)

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