An apparatus usable to apply torque to a sucker rod connection is described herein. The apparatus includes an insert for installation within a tong device configured to provide torque to a tubular, the insert adapting the tong to engage and apply torque to a sucker rod segment. The insert can include a flange secured to the tong device, a tubular body extending through the opening of the tong device and engaging gripping members of the tong, and an engagement member having a slot sized to engage a sucker rod segment. A back-up tong device can be used to retain a lower sucker rod segment while an upper sucker rod segment is torqued by the tong device. The back-up tong device and/or the tong and insert can be pivotably or rotatably movable for engaging a lower sucker rod segment that is not in rotational alignment with the upper sucker rod segment.

A device for boring a well with casing. The device is attached to a motor that has a power shaft for imparting rotational movement. The device comprises a driver operatively connected to the power shaft, with the driver containing a cylindrical body, a first bit having a first end connected to the driver so that rotational movement of the driver is imparted to the first bit, and a sleeve disposed about the power shaft, and wherein the sleeve has a radial shoulder. The device further includes casing attached to the sleeve, and wherein the casing is designed to be permanently placed within the well once the boring is completed. The device further comprises a housing disposed about the driver, a second bit attached to the housing, and a planetary gear anchored to the radial shoulder, and wherein the planetary gear is adapted for imparting rotation from the driver to the housing in a counter radial direction.

The device includes a driver operatively connected to the power shaft, with the driver containing a cylindrical body, a first bit having a first end connected to the driver so that rotational movement of the driver is imparted to the first bit, and a sleeve disposed about the power shaft. The device further includes a housing disposed about the driver, and a second bit attached to the housing. Through engagement of cogs and pinions, rotation of the first bit in a first direction using the driver causes counter rotation of the second bit in an opposite direction, significantly reducing or eliminating reactive torque produced during drilling.

A device for boring a well is provided, the device being attached to a motor having a power shaft for imparting rotational movement responsive to a fluid flow. The device includes a driver operatively connected to the power shaft, the driver having a tubular body with an internal bore for accommodating fluid flow, a first bit connected to the driver at a first end so that rotational movement of the driver is imparted to the first bit, and an inner bore. A second bit is attached to housing about the first bit. A nozzle communicating the internal portion of the tubular body with an outer portion thereof, the nozzle being oriented to deliver a portion of the fluid flow to the second bit.

An apparatus for steering a drill string is disclosed herein, the apparatus comprising a drilling motor comprising a rotor, a stator, and at least one fluid passage for flowing drilling fluid to the stator. A blade is fixedly disposed on the exterior surface of the stator. A diverter valve controls the flow rate of drilling fluid to the stator, to provide counter rotational movement to the stator with respect to the rotor. Placement and movement of the blade is thereby controlled. When the blade is rotated such that it remains stationary with respect to a fixed point in a borehole, the drill bit is turned. When the blade is counter-rotated in a constant motion with respect to the rotor, the drill bit continues to drill in a straight direction.
