A casing puller includes a body and at least one arm. The body has first and second ends, at least one end connectable to a drill pipe. The body defines a longitudinal axis and sized for insertion into a casing pipe. The at least one arm is disposed on the body and moves between a stowed position and a deployed position. The at least one arm extends away from the longitudinal axis when in its deployed position and is arranged to engage an arm receiver defined by the casing pipe.

A pipe retriever (100) for retrieving an unsecured pipe (15) has a head (110) connectabie to a drilling pipe (20) and defines a longitudinal axis (H). The longitudinal axis of the head is arranged parallel to a longitudinal axis (P) of the drilling pipe when connected. A tail (200) extends from the head at an angle (a) with respect to the longitudinal axis. The tail defines a hook shape (210) having inward and outward surfaces (220, 230). The inward hook surface defines a pipe recess (222) sized to receive the unsecured pipe.
A pipe retriever for retrieving an unsecured pipe has a head connectable to a drilling pipe and defines a longitudinal axis. The longitudinal axis of the head is arranged substantially parallel to a longitudinal axis of the drilling pipe when connected. A tail extends from the head at an angle with respect to the longitudinal axis. The tail defines a hook shape having inward and outward surfaces. The inward hook surface defines a pipe recess sized to receive the unsecured pipe.

A remote controlled vehicle includes a chassis, front and rear axles mounted on the chassis and at least one wheel coupled to each axle. A front hydraulic drive drives the front axle and a rear hydraulic drive drives the rear axle. The remote controlled vehicle includes front and rear control valves in fluid communication with the corresponding front and rear hydraulic drives for regulating at least one of a fluid direction and a fluid flow through each control valve to each corresponding hydraulic drive. A controller communicates drive commands to each hydraulic drive and receives the drive commands front an external communicator. The chassis has a width substantially equal to the widest width of the reservoir and the motor.

A method of directional drilling includes forming first and second pits on corresponding first and second sides of a barrier, forming a pilot bore from the first pit to the second pit, enlarging the pilot bore to a final bore, and extending a cable through the final bore between the first and second pits by attaching the cable to a remote controlled vehicle and driving the remote controlled vehicle through the final bore from one of the pits to the other pit. The method also includes pulling a pipeline through the final bore using the cable.
A reamer includes a mandrel defining a mandrel axis and arms extending radially from the mandrel. Each arm has a proximal end and a distal end. The reamer includes a cutting head disposed on the distal end of each arm and cutting teeth disposed on each cutting head. The cutting heads are arcuately spaced about the central mandrel to allow the movement of debris axially along the central mandrel and at least one of the arms defines a square cross-sectional shape.
An apparatus and method for horizontal drilling are provided. The apparatus has: (A) a thrust frame; (B) a carriage on the thrust frame; (C) a wheel truck, wherein a rearward portion of the thrust frame can be supported in a lowered position on the wheel truck; (D) a king pin for operatively connecting a forward portion of the thrust frame to a tractor; (E) a trailer-leg assembly that can be connected operatively between: (i) the forward portion of the thrust frame; and (ii) the ground; and wherein the trailer-leg assembly is capable of assisting in supporting the forward portion of the thrust frame: (a) in a raised position so a tractor can be connected for towing; and (b) in a lowered position where the forward portion of the thrust frame is in a lowered position adjacent the ground to assist in positioning the thrust frame in a position for drilling.
A reamer for underground boring is provided. The reamer includes at least: (a) a center mandrel, wherein the center mandrel defines a mandrel axis; (b) a plurality of radial members extending radially from the center mandrel; (c) a plurality of cutting heads, wherein each of the cutting heads: (i) is supported by at least one of the radial members; (ii) is arcuately spaced-apart around the center mandrel from the other cutting heads; (iii) has a rounded surface; and (d) a plurality of cutting teeth on the rounded surface of each of the cutting heads. A method of horizontal drilling with the reamer is also provided.
