Abstract: A mobile coiled tubing rig and method for obtaining samples from a formation. The rig having a carrier, a coiled tubing reel positioned on the carrier, a mast pivotally mounted on the carrier, a coiled tubing injector mounted on the mast, at least one wrench for connecting components to the coiled tubing and to each other to form the bottom hole assembly. The rig is operable to perform earth coring operations and/or reverse circulation drilling to obtain samples of a formation for analysis.

Abstract: A system and method for horizontally building stands of tubulars and transferring them to a rig floor. The system has a horizontal stand builder which assembles double or triple stands of tubulars. A catwalk and V-door are positioned alongside the horizontal stand builder. A skate is able to push either single, double, or triple stands along the catwalk and up the V-door to a position whereby an elevator on the rig can grip the stand and move it onto the rig. For transferring single stands of tubular, there is a carrier at the upper end of the V-door which can grip the single stand and lift it to the position for the elevator to grip it and move it onto the rig.

Abstract: A tailing arm mountable on a mast of an oil/gas rig and having a housing, a first arm rotatable relative to the housing, a second telescoping arm pivotally connected to the first, and third arm pivotally connected to the second arm. A roller on the end of the third arm receives and guides pipes being moved on to or off of the rig. A first rotation assembly controls the rotation of the first arm relative to the housing. A second rotation assembly rotates the housing relative to the mast. The tailing arm can be used to load pipe from multiple sides of the rig and to rack the pipe in the setback.

Abstract: There is a new and useful invention for the cutting, processing and mixing of material. The invention is comprised of a vertical mixer containing stationary knives interacting with rotating knives. The stationary knives mounted on the tub wall interact with the rotating knives mounted on the radial edge of the rotating auger. This interaction facilitates cutting of large, coarse and dense materials otherwise not readily processed by vertical mixers.
