Operations Manual
Vertical Hold (VHOLD) – In VHOLD mode, the tool will actively steer the wellbore to a vertical inclination when the inclination the tool records is over 0.5 degree. The tool continuously steers to vertical but does not seek out a specific coordinate, if the desired goal is to stay directly under the surface location, magnetic steering may be required to bring the well back under the well head in highly deviated formations. Neutral Mode (NTRL) – In NTRL mode the tools valve turns freely, not allowing the pistons to extend with the necessary force or at a target toolface to deviate the BHA. NTRL mode is used for tool transport and for drilling the shoe, tripping, and extended reaming operations.
