Patent number: 8646523Abstract: Porous objects, such as porous balls, may be employed within telescoping devices to control proppant flowback through a completed well during production. The telescoping devices may connect a reservoir face to a production liner without perforating. Acid-soluble plugs initially disposed within the telescoping devices may provide enough resistance to enable the telescoping devices to extend out from the production liner under hydraulic pressure. The plugs may then be dissolved in an acidic solution, which may also be used as the hydraulic extension fluid. After the plugs are substantially removed from the telescoping devices, the reservoir may be hydraulically fractured using standard fracturing processes. The porous balls may then be inserted into the telescoping devices to block proppant used in the fracturing process from flowing out of the reservoir with the production fluids.Type: GrantFiled: June 14, 2010Date of Patent: February 11, 2014Assignee: Baker Hughes IncorporatedInventors: Tianping Huang, Richard YingQing Xu

Publication number: 20120267119Abstract: A technique facilitates actuation of a downhole tool, such as a valve, in a simple, rapid, and cost-effective manner. The technique comprises installing the downhole tool with a trip saver. The trip saver can be actuated by increasing a tubing pressure or other suitable pressure source beyond a threshold level. Once the trip saver is actuated, a fluid under suitable pressure is provided to a downhole tool through a passageway opened via the trip saver. This enables actuation of the downhole tool to a desired state.Type: ApplicationFiled: November 8, 2011Publication date: October 25, 2012Inventor: Dinesh R. Patel

Patent number: 8291980Abstract: A tubular valving system includes a tubular having a plurality of ports. A plurality of sleeves are disposed at the tubular covering the plurality of ports, and a plug runnable within the tubular is seatingly engagable with the plurality of sleeves such that attainment of a first pressure applied against the plug and one of the plurality of sleeves causes movement of the one of the plurality of sleeves to thereby uncover at least one of the plurality of ports covered by the one of the plurality of sleeves. At least one of the plurality of sleeves is yieldable to allow passage of the plug upon attainment of a second pressure applied thereagainst, and a plurality of occlusive members occlude the plurality of uncovered ports until a later time.Type: GrantFiled: August 13, 2009Date of Patent: October 23, 2012Assignee: Baker Hughes IncorporatedInventor: Peter J. Fay

Patent number: 8276670Abstract: A downhole plug can include a housing having an aperture disposed generally through the center of the housing. A stopper can be disposed in the aperture and adapted to block fluid flow therethrough. The stopper can have a composition of at least two different materials. One or more covers can be at least partially disposed on the stopper, wherein and the stopper can be at least partially encapsulated by the one or more covers. A flow control device can be disposed adjacent the stopper to selectively introduce fluid to at least a portion of the stopper.Type: GrantFiled: April 27, 2009Date of Patent: October 2, 2012Assignee: Schlumberger Technology CorporationInventor: Dinesh R. Patel

Publication number: 20120241143Abstract: Well tools including valves operable by low electrical input. One well tool includes a valve which controls fluid communication between pressure regions in a well, the valve including a rotatable member which is biased to rotate, and a brake or clutch which prevents rotation of the member. Another valve includes a barrier which separates reactants, with the valve being operable in response to the barrier being opened and the reactants thereby reacting with each other. Yet another valve includes a barrier which separates the pressure regions, and a control circuit which heats the barrier to a weakened state. Another valve includes a member displaceable between open and closed positions, a restraining device which resists displacement of the member, and a control device which degrades or deactivates the restraining device and thereby permits the member to displace between its open and closed positions, in response to receipt of a predetermined signal.Type: ApplicationFiled: June 6, 2012Publication date: September 27, 2012Applicant: HALLIBURTON ENERGY SERVICES, INC.Inventors: Adam D. Wright, Michael L. Fripp, Kevin D. Fink, Donald Perkins, Jimmie R. Williamson, Mark D. Kalman

Publication number: 20120234545Abstract: A valving system includes a tubular and a sleeve slidably engaged with the tubular having a seat thereon. The sleeve is configured to occlude flow from an inside of the tubular to an outside of the tubular when in a first position, allow flow between an inside of the tubular and an outside of the tubular at a first location upstream of the seat and a second location downstream of the seat when in a second position, and allow flow between an inside of the tubular and an outside at the tubular at the first location and not the second location when in a third position. The valving system also includes a disappearing member in operable communication with the tubular and the sleeve configured to prevent movement of the sleeve to the third position until disappearance thereof.Type: ApplicationFiled: March 14, 2011Publication date: September 20, 2012Applicant: BAKER HUGHES INCORPORATEDInventor: Richard YingQing Xu

Patent number: 8267177Abstract: A plug for a pipe in an oil or gas well includes a packer, a slip ring and a cone disposable on a mandrel and pressed between an upper push sleeve and a lower anvil on the mandrel. The plug can be field configurable with a frac plug kit, a bridge plug kit and a soluble insert plug kit. A pair of concentric locking rings is disposed between the push sleeve and the mandrel with an outer annular cone with an outer conical shape tapered upwardly and inwardly.Type: GrantFiled: August 28, 2009Date of Patent: September 18, 2012Assignee: Exelis Inc.Inventors: Jason Jon Vogel, Randall Williams Nish, Randy Arthur Jones

Patent number: 8267178Abstract: A valve for use in fracing through cement casing in a well allows for flow of cement down the well during the cementing process and in the open position allows for fracing fluid to be directed through the cement casing for fracturing the formation adjacent the valve. The valve is constructed so as to reduce the likelihood of the valve to jam as a result of cement or other foreign material.Type: GrantFiled: September 1, 2011Date of Patent: September 18, 2012Assignee: Team Oil Tools, LPInventors: Michael T. Sommers, Stephen L. Jackson
