Vertical curvature for deviated wells

Input(s)

$\mathrm{I}_{\mathrm{a}}$: Original Hole Inclination (degree)

$\mathrm{I}_{\mathrm{b}}$: Desired Hole Inclination (degree)

$\partial \mathrm{L}$: Course Length $(\mathrm{ft})$

Output(s)

VC: Vertical Curvature (degree/ft)

Formula(s)

$$ \mathrm{VC}=\left(\mathrm{I}_{\mathrm{b}}-\mathrm{I}_{\mathrm{a}}\right) * \frac{100}{\partial L} $$
