Drill String Design As inclination angle increases in a directional or horizontal well, the borehole walls support more of the drill string weight. This contact, along with the capstan effect (the normal force caused by the deformation of an axially loaded member about some obstacle), results in frictional forces that oppose the …

Horizontal drilling is the process of directing part of a well course through a reservoir such that its inclination angle is approximately 90° from vertical.

Directional drilling is the practice of accessing an underground oil or gas reserve by drilling in a non-vertical direction. Directional...

Hydraulic fracturing is a type of well stimulation treatment designed to bypass near-wellbore formation damage and create an improved ...
