    Abstract: A method of steering a drill bit to form an opening in a subsurface formation, comprises a) determining a distance from design of a well, and b) determining an angle offset from design of the well wherein angle offset from design is the difference between the inclination and azimuth of the hole and the inclination and azimuth of plan, c) wherein at least one distance from design and at least one angle offset from design are determined in real time based, at least in part, on a position of the hole at the last survey, a position at a projected current location of the bit, and a projected position of the bit.

    Abstract: A method of automatically placing a drill bit used to form an opening in a subsurface formation on a bottom of the opening being formed comprises a) increasing a flow rate in a drill string to a target flow; b) controlling a flow rate of fluid into the drill string to be substantially the same as a flowrate of fluid out of the opening; c) allowing a fluid pressure to reach a relatively steady state; and d) automatically moving the drill bit toward the bottom of the opening at a selected rate of advance until an increase in measured differential pressure indicates that the drill bit is at the bottom of the opening.
