Patent number: 10704361Abstract: An injection sleeve and apparatus for injecting fluid into a well includes a flow tube having a piston which upon fluid flow opens one or more outlet ports. The injection sleeve is adapted to include a variable orifice insert which prevents flow through the tool at a first selected pressure level until the outlet ports are in an open position, thereby protecting packing seals on either side of the outlet ports from undue wear and tear, and prolonging the life of the tool. At a second pressure level, the variable orifice insert permits flow through injection sleeve to the formation injection zones. A plurality of the sleeves may be used for sequentially injecting fluid into a plurality of injection formation zones surrounding a well. When injection fluid flow is terminated, the injection sleeves act as a dual barrier valve for preventing flow from the injection formation zones back to the well head.Type: GrantFiled: June 20, 2018Date of Patent: July 7, 2020Assignee: TEJAS RESEARCH & ENGINEERING, LLCInventors: Jason C.

Patent number: 10458203Abstract: A method and apparatus for completing a well that includes a subsurface barrier valve utilizes an injection valve which includes a variable orifice insert. The injection valve includes a mechanism for sensing pressure cycles that are employed during various well completion operations including pressure testing. The mechanism includes an indexing sleeve which will disable pressure functionality. Once this occurs, pressure cycling to open the barrier valve can proceed. Once the barrier valve opens, flow alone controls the injection valve during normal operations.Type: GrantFiled: April 10, 2017Date of Patent: October 29, 2019Assignee: Tejas Research & Engineering, LLCInventors: Jason C.

Patent number: 10443338Abstract: In a fracking context the object that will ultimately block a passage in an isolation device is introduced into the zone with the bottom hole assembly. The object is not released until the guns fire to create a pressure spike in the borehole that triggers the object retaining device to release the object. The retaining device is placed in close proximity to the isolation device and its setting tool to allow a larger object and passage in the isolation device to be used. If the guns misfire, the object is not released and comes out with the guns. The replacement guns can be pumped in because the passage in the isolation device has stayed open during the misfire. Direct and indirect object release in response to pressure created from the firing of the guns is contemplated.Type: GrantFiled: October 4, 2017Date of Patent: October 15, 2019Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Jason C.

Patent number: 10190390Abstract: A shifting sleeve has differential piston areas so that applied pressure displaces the sleeve against spring bias, which preferably is a series of Belleville washer stacks associated with modular mandrel components, to obtain the desired opposing force to the movement initiated with pressure applied to differential piston areas. An indexing feature is located between the sleeve and the mandrel passage wall and on a predetermined number of cycles disables the Belleville washer stacks from biasing the sleeve in an opposed direction as when pressure is applied. At this time the pressure in the mandrel acting on the differential piston area simply shifts the sleeve to open a lateral port so that fracturing through the cement that was earlier placed with the port closed can take place.Type: GrantFiled: August 5, 2015Date of Patent: January 29, 2019Inventors: Jason C.

Patent number: 9816350Abstract: A ported sub is operated with a pressure actuated shifting sleeve. A first rupture disc is set at a lower pressure than the test pressure for the tubing string that houses the ported sub. The first rupture disc breaks at a lower pressure than the string test pressure to expose well fluids to a disintegrating plug. The plug slowly disintegrates to then expose tubing pressure to a chamber and a second rupture disc with the chamber configured to have no effect on moving the sliding sleeve. When the tubing pressure is then raised to a predetermined pressure below the test pressure for the string, the second disc breaks exposing a piston to tubing pressure on one side and trapped low pressure being the opposite side of the string. The differential moves the sleeve to open a port to let tools be pumped into position without a need to perforate.Type: GrantFiled: May 5, 2014Date of Patent: November 14, 2017Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Jason C.
