Abstract: A brake system for maintaining an angular position of a spindle assembly. A pump-powered motor drives rotation of a spindle on the machine. When no rotation is desired, the spindle will slow, then stop at a desired angular orientation. A rotational sensor will determine the clock position, and a controller compares that to a desired angular orientation. If an error tolerance is exceeded, the motor will rotate the spindle back to the desired orientation.

Abstract: A system for tracking and steering a downhole tool using an augmented reality device. A tracker tracks the location of a downhole tool as it moves underground and transmits data to the device, while one or more sensors measure a position and orientation of the device. The device analyzes the data received from the tracker and the sensors and generates a virtual image of the downhole tool. The virtual image is displayed on the device at its detected location relative to the ground surface and relative to the position of the device. The position of the displayed virtual image is modified in response to updated information from the tracker or the sensors. Virtual images representing various parameters of the drilling operation are also displayed on the device in juxtaposition with the virtual image of the downhole tool.

Abstract: A bending apparatus for coiled tubing protects the entire path of coiled tubing from the reel to the injector, while still protecting a main controlled bend from the reel to the injector. The bending apparatus includes a conduit having a bend portion and a flexible portion. The main controlled bend is isolated in the bend portion, while a smaller adjustment bend is designed for the flexible portion. The changes in the upright angle from dispensing coiled tubing from different levels of the reel no longer cause damage. The changes in the lateral angle from dispensing coiled tubing from both sides of the reel no longer cause damage. A table mount can also be added to allow more adjustment for changes in the lateral angle.

Abstract: A wellbore tool is conditioned between downhole deployments with a substantially continuous application of a conditioning fluid within the tool. Selectively removable caps connect to ends of the tool after its removal from the wellbore. If the tool is part of a downhole string, the caps are added after the tool is decoupled from the remainder of the string. The conditioning fluid is introduced into the tool through a fitting on one of the end caps; and while a fitting on the other end cap is opened to vent fluids resident within the tool. The caps are in sealing contact with a housing of the tool to retain the conditioning fluid inside the tool. A fluid supply system at the well site provides the conditioning fluid. Example conditioning fluids include a fracturing fluid, a completion fluid, a diluent, a solubilizing agent, an anti-scaling agent, a pH buffer, a liquid freezing point depressant, corrosion and oxidation inhibitors, oxygen scavengers, biocides, surfactants, and combinations thereof.
