  • Hole Deviation - Fordia

    2015-6-29 · Hole deviation is the unintentional departure of the drill bit from a preselected borehole trajectory. Whether it involves drilling a straight or curved-hole section, the tendency of the bit to walk away from the desired path can lead to drilling problems such as higher drilling costs and also lease-boundary legal problems Fig. 1 provides examples of hole deviations.
