Abstract: A method includes drilling a first bore into a formation to a first depth, the bore having a bore wall and a first diameter that is sufficient to receive a casing pipe. A casing pipe is driven into the drill bore, the casing pipe having a binder on an exterior surface of the casing pipe that is configured to secure the casing pipe to the bore wall, the casing pipe being secured to an anchoring nut at a proximal end. The anchoring nut includes a gripping feature. An anchoring clamp of a drill rig is engaged with the gripping feature of the anchoring nut to thereby anchor the drill rig to the formation. The anchoring clamp includes a plurality of jaws that are movable toward and away from a central axis.

Abstract: A drill rig having a longitudinal drilling axis, a front portion, and a rear portion can comprise a feedframe aligned with the longitudinal drilling axis, a first head assembly coupled to the feedframe and configured to rotate a drill string, and a rod holder proximate the front portion of the drill rig. A second head assembly can be movable on the feedframe along the longitudinal axis and can include a powered water swivel assembly comprising a spindle having an interior bore a drill rod connector at a first end of the spindle, a motor that is configured to rotate the spindle, a clutch configured to disengage the motor from the spindle, a gearbox that couples the motor to the spindle, and a water swivel that is configured to provide drilling fluid to the interior bore of the spindle.
