Lateral load imposed on a casing centralizer - Cementing

Input(s)

$m$: Steel in Mud Buoyancy Factor (dimensionless)

$W$: Weight per foot of Casing (lbm)

L: Distance from Centralizer to next Lower Centralizer $(\mathrm{ft})$

$\theta$: Borehole Angle (degree)

$T$: Tension (Pulling Force) due to casing below Centralizer (lbm)

$\delta$: One-half the change in Angle between Centralizer and next Lower Centralizer (degrees)

Output(s)

$F_{L}$: Lateral Load, Casing Weight Component $\pm$ Tension Component (lbm)

Formula(s)

$$ F_{L}=m \cdot W \cdot L \cdot \sin \theta \pm 2(T) \sin \delta $$
