Publication number: 20180135373Abstract: A methodology and apparatus for cutting shape(s) or profile(s) through well tubular(s), or for completely circumferentially severing through multiple tubulars, including all tubing, pipe, casing, liners, cement, other material encountered in tubular annuli. This rigless apparatus utilizes a computer controlled, downhole robotic three-axis rotary mill to effectively generate a shape(s) or profile(s) through, or to completely sever in a 360 degree horizontal plane wells with multiple, nested strings of tubulars whether the tubulars are concentrically aligned or eccentrically aligned. This is useful for well abandonment and decommissioning where complete severance is necessitated and explosives are prohibited, or in situations requiring a precise window or other shape to be cut through a single tubular or plurality of tubulars.Type: ApplicationFiled: August 28, 2017Publication date: May 17, 2018Inventors: Wesley Mark McAfee, Mark Franklin Alley

Patent number: 8833444Abstract: A system, apparatus and method for abrasive jet fluid cutting is provided wherein an abrasive jet fluid cutting assembly comprises a hose for receiving a coherent abrasive jet-fluid containing a solid abrasive; a helix/spring attached inside the high-pressure hose; and a jet-nozzle connected to the hose. Wherein the coherent abrasive laden jet-fluid is pumped under high pressure through the high-pressure hose and across the helix. As the jet-fluid traverses the helix, the jet-fluid rotates at a high rate creating a vortex. The disclosed subject matter further includes a system and method for using the abrasive jet fluid cutting nozzle assembly.Type: GrantFiled: February 6, 2013Date of Patent: September 16, 2014Inventors: Wesley Mark McAfee, Mark Franklin Alley

Patent number: 8585909Abstract: This invention relates generally to a method and apparatus to allow high pressure pumping a fluid mixture of solid and/or abrasive particles with a liquid, and separating the fluid mixture into a solid and/or abrasive particle component and a cleaned liquid component. An embodiment includes surrounding the pump plunger/piston, and timely cycling the cleaned liquid to flush the pump check valves to displace erosive solid and/or abrasive material. Consequently, this invention allows for proper check valve sealing, extends the life of check valves, extends the life of the pump, and improves efficiency.Type: GrantFiled: September 1, 2012Date of Patent: November 19, 2013Inventors: Wesley Mark McAfee, Mark Franklin Alley
