Rotating the drill string causes the bent housing with drill bit attached to changes direction.
To provide a more positive control, the deflection shoe was used with stabilizers on the motor, rather than the bent housing. Being near the sidetracker bit, the shoe stabilized the tool and positive deflection effect.
A complete selection of fixed or adjustable bent housings; slick or eccentric housings; and wear protection are standard.
Bent housings on the motors also vary, from 0.5 to 2.5 degrees depending on how sharp an angle the driller needs to build the curve; this can be anywhere from 12.5 to 19 degrees per 100 feet according to Vlado Katic, president of Guided Horizontal Drilling.
