SlimDril’s Wireline Steering Tool is a directional guidance system that provides real time positioning of the borehole. Sensors located within the downhole probe provide constant updates of inclination, azimuth and tool face orientation to the surface via a wireline. The data is processed utilizing surface equipment (interference unit, laptop computer and printer) and specialized steering software to provide information on depth, course length (Away) and distance off the predetermined azimuth (Right/Left).
