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