The course covers to moderate practices angle well bores, extended reach and horizontal drilling. Loads simple drill stem design for vertical applied by tension, combined torsion, burst pressure, collapse pressure, compression, slip and stability forces are considered. Design steps to reduce fatigue damage are also covered.
