| 20120083944 | Remote Controlled Vehicle - 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. | 04-05-2012 |
| 20100263936 | Reamers and Methods for Directional Drilling - 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 arms 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. | 10-21-2010 |
| 20100224381 | Mobile Self-Erecting Directional Drilling Rig Apparatus - 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. | 09-09-2010 |
