Patent number: 10301908Abstract: An array of sliding sleeve valves are uniquely addressable without control lines or wires to open for a treatment and then close and then selectively open for production. The discrete movements employ an available pressure source such as tubing pressure and change the piston areas on opposed sides of a sliding sleeve valve to get the desired movements. Access valves to tubing pressure can be actuated in a desired sequence with signals such as acoustic or electromagnetic, for example. Access to one piston area that communicates opposed and offsetting piston areas to the tubing hydrostatic can be achieved with a straddle tool breaking a rupture disc. The piston is then in pressure balanced and can be moved in a desired direction with the straddle tool straddling access locations to the piston from above or below.Type: GrantFiled: February 9, 2017Date of Patent: May 28, 2019Assignees: BAKER HUGHES, A GE COMPANY, LLC, CHEVRON USA, INC.Inventors: John K. Wakefield, Alexander Kendall, Stephen A. Graham, Pete J. Clark

Patent number: 10253594Abstract: A zone to be treated comprises a plurality of sliding sleeve valves. The sleeve defined opposed chambers charged with pressurized fluid on opposed sides of the sleeve. Valves responsive to a remote signal with no borehole intervention change the pressure balance on the sleeve to get it to open from a closed position and then close and then to reopen for production. One way this is done is by sequential pressure bleeding off from the opposed chambers. A zone having multiple such valves can be treated without need for dropping balls and subsequent milling out, which allows production to commence sooner with reduced restrictions to flow from the ball seats and without the debris associated from a milling operation.Type: GrantFiled: December 9, 2016Date of Patent: April 9, 2019Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: John K.

Patent number: 5715891Abstract: In a cased wellbore having one or more cased and cemented drainholes extending therefrom such that the elliptical shaped opening or junction of each drainhole with the primary well is sealed and cut flush with the inside of the primary well casing, an inventive method is disclosed for: (a) isolating each perforated and/or drainhole completion within the primary wellbore, (b) providing flow control means for each completion to permit selective testing, stimulation, production, or abandonment, and (c) facilitating selective re-entry into any cased drainhole for conducting additional drilling, completion, or remedial work. In a preferred embodiment, a production liner is permanently attached within the primary well casing such that packers straddle permanent flow control devices and precut liner windows which are positioned adjacent to perforated completions and drainhole entrance openings, respectively.Type: GrantFiled: September 27, 1995Date of Patent: February 10, 1998Assignee: Natural Reserves Group, Inc.Inventor: Stephen A.

Patent number: 5337808Abstract: A vertical cased well penetrates two or more hydrocarbon bearing formations. A deviated well includes a horizontal drain hole extending a substantial distance into at least one of the formations. A production string is cemented in the horizontal drain hole and is cut off inside the vertical cased well. Perforations through the vertical cased well communicate the well with some or all of the formations. A production assembly in the vertical cased well includes a series of external casing packers isolating the hydrocarbon bearing formations. Wire wrapped port collars between the external casing packers controls flow into the production assembly and upwardly through the well. A resin coated sand may be plated in the annulus between the production assembly and the vertical casing to control the production of formation solids.Type: GrantFiled: November 20, 1992Date of Patent: August 16, 1994Assignee: Natural Reserves Group, Inc.Inventor: Stephen A.

Patent number: 5301760Abstract: A horizontal bore hole is sidetracked through a window cut in a cased vertical well or from a vertical open hole shaft extending below the kickoff point. In one embodiment, a whipstock is used. In another embodiment, the cased vertical well provides a drillable joint so the window can be cut with a conventional bent housing mud motor from a cement plug located adjacent the drillable joint at the kickoff point. In yet another embodiment, a cement plug is dressed down to the kickoff point in a vertical open hole and is used to start the curved well bore. After drilling at least the curved bore hole, a production string extending into the vertical well is cemented in the curved bore hole and then cut off inside the vertical cased hole with a conventional burning shoe/wash pipe assembly. The whipstock or cement plug is removed to clear the vertical well to a location below the entry of the horizontal well bore. Multiple horizontal wells may be drilled.Type: GrantFiled: September 10, 1992Date of Patent: April 12, 1994Assignee: Natural Reserves Group, Inc.Inventor: Stephen A. Graham

Patent number: 5289876Abstract: A method of completing a horizontal well in an incompetent formation includes running a pipe string into the horizontal well bore, pumping a hardenable permeable material into the horizontal well bore, allowing the hardenable material to set up and then drilling up at least part of the pipe string. The hardenable permeable material may be resin coated sand providing sand control for the incompetent formation. In the event the horizontal bore hole vertically meanders out of a desired path and falls below an oil-water contact or rises above a gas-oil contact, that portion of the pipe string located out of the desired path is not drilled up thereby deterring production of undesired formation fluids.Type: GrantFiled: July 28, 1992Date of Patent: March 1, 1994Assignee: Natural Reserves Group, Inc.Inventor: Stephen A.
