A rotor bolt is connected to the upper end of the rotor, and is supported for axial movement within a rotor bolt housing from a running position to a deployed position. If the stator housing breaks or backs off, the attached rotor bolt shifts to the deployed position. In the deployed position, the bolt substantially reduces flow to the stator housing and simultaneously opens bypass ports to vent fluid to the annulus instead. In this way, the rotor is prevented from spinning rapidly, the diverted fluid creates a pressure change that alerts the operator to the motor failure, and the diverted fluid allows continued removal of debris and cuttings from the well bore. | 03-06-2014 |

20140048247 | HYDRAULIC JAR WITH LOW RESET FORCE - A hydraulic jar for delivering impacts downhole. The jarring mechanism includes a cup-type piston that moves through a seal bore. The cup is deformable in response to fluid pressure so that it expands each time it moves through the seal bore to compensate for wear on the lip. Since only minimum interference is required between the piston and seal bore, less material may be used. This reduces the force required to reset the tool, which is particularly advantageous in horizontal wells. The seal bore may be slightly wider at the exit; the cup expands to this exit diameter, ensuring an interference fit as the cup travels back through the smaller diameter entry section. The entry end of the seal bore may include longitudinal grooves. This prevents the piston cup from rupturing by preventing a fluid seal around the lip until the most of cup is inside the seal bore. | 02-20-2014 |

20130192830 | Limited Depth Abrasive Jet Cutter - Tools and methods for abrasively cutting downhole pipes and casing. The tools and methods are ideally suited for situations where the pipe to be cut or perforated is positioned partly or wholly inside another pipe and damage to the outer pipe must be avoided. The jet nozzles are positioned at a non-normal angle to the target surface to reduce the jets' effective cutting distance. While pumping the abrasive fluid, the jets are supported at a selected radial distance from the target surface so that within a predetermined operating time the jets will cut or perforate the inner pipe but leave the outer pipe substantially intact. The tool may be rotated with a motor to perform cutoff operations or held in a fixed position for perforating. | 08-01-2013 |
20130000909 | Jarring Method and Apparatus Using Fluid Pressure to Reset Jar - A method and apparatus for delivering repetitive jarring impacts to a stuck object downhole. The jarring tool is deployed on coiled tubing or other tubular well conduit, and fluid pressure is used to cycle the jar without reciprocating the well conduit at the wellhead.

20110114316 | Methods and Devices for One Trip Plugging and Perforating of Oil and Gas Wells - A tubing conveyed tool for use in perforating a well bore utilizing abrasive perforating techniques. The perforating tool is particularly useful in non-vertical wells. The perforating tool is designed to permit running and setting a bridge plug, and then perforating the well bore without requiring the removal of the tool string. An eccentric weight bar can also be used to allow for directional perforating in non-vertical wells. The eccentric weight bar uses gravity to cause the bar to rotate to a predetermined position. | 05-19-2011 |
20100276204 | VIBRATING TOOL - A vibrating tool comprising a hammer and valve that oscillate axially inside a housing to produce vibrations solely in response to fluid flow through the tool at an operating flow rate. The valve is supported by a spring that resists compression until a minimum operating flow rate is achieved, and hammer is also spring-loaded. When the valve strokes down and engages the hammer, flow through the hammer is restricted. Increased fluid pressure pushes the hammer down away from the valve, resulting in a sudden decrease in pressure, allowing both the hammer and valve to rebound and create vibrational impacts. The cycle repeats continuously as long as an adequate flow rate is maintained. | 11-04-2010 |
