Patent number: 8770299Abstract: A tubular actuating system includes a plurality of series of actuators disposed within a tubular with at least one of the series having a plurality of actuators. Each of the plurality of actuators in the at least one of the series is alterable from a first position allowing passage of plugs below a selected size to a second position allowing actuation by plugs of selected sizes. The plurality of actuators of the series are distributed within the tubular such that the more upstream of any two of the plurality of actuators is actuatingly engagable with a larger one of the plugs than the more downstream of the two of the plurality of actuators when in the second position, and the plurality of series is distributed such that for any two of the series the more upstream of the two series requires a larger plug to alter the actuators therewithin.Type: GrantFiled: April 19, 2011Date of Patent: July 8, 2014Assignee: Baker Hughes IncorporatedInventor: James G. King

Patent number: 8763707Abstract: A downhole circulating valve includes a generally tubular outer housing having an axially extending internal passageway including an internal seat and at least one generally radially extending opening formed through the housing intersecting the internal seat. A valve element is rotatably disposed within the internal passageway. The valve element has an axially extending internal bore and a head portion disposed at least partially within the internal seat. The head portion includes at least one generally radially extending seal element. The valve element has a first position relative to the housing, wherein the seal element is not aligned with the opening, thereby allowing fluid communication between the opening and the internal passageway.Type: GrantFiled: January 20, 2013Date of Patent: July 1, 2014Assignee: Halliburton Energy Services, Inc.Inventors: Jimmie Robert Williamson, Leo G. Collins, David L. Reesing, Russell Irving Bayh, III

Patent number: 8763688Abstract: A rubber bullet-shaped cylindrical device that functions to non-invasively plug a gushing pipe of high pressure oil. The steel belted inflatable rubber plugging device with attached high pressure hoses is inserted into a gushing oil well pipe while it pumps shipboard a high pressure stream of recycled oil itself that will not freeze at the gushing oil well to fight or knife through the oil and the pressure of the oil gushing to assist with inserting and descending the apparatus into the pipe while the operator follows a sequence of operational steps. A hose that has a vacuum applied to reduce the size of the inflatable bladder to allow it to fit it into the pipe unrestricted until it stops at the right location then recycled oil that will not freeze is pumped into the bladder to seal the oil well and to allow the cement pouring operation.Type: GrantFiled: August 5, 2011Date of Patent: July 1, 2014Inventor: John Karl Webb, Jr.

Patent number: 8757267Abstract: A pressure-actuated valve fit to a tubing string for alternately closing to communicate fluids from a wellbore to the tubing string and opening to communicate fluids from a wellbore annulus to the tubing string. The valve is particularly useful for lifting liquids which accumulate in the tubing string when the reservoir has a diminished pressure. In this case, gas is accumulated in the wellbore annulus and when the valve is opened the gas enters the valve and is directed to the tubing string for lifting the liquids. The valve is closed by a spring and has a closing-assist which applies an additional force to the spring to ensure the valve is fully closed.Type: GrantFiled: December 20, 2011Date of Patent: June 24, 2014Inventors: Bruce Mitchell, Gordon Bosley

Patent number: 8757273Abstract: A method for opening a port through the wall of a ported sub including providing a sub with a port through its tubular side wall and providing a hydraulically actuatable valve to cover the port, the valve being actuatable to move away from a position covering the port to thereby open the port. The method further includes increasing pressure within the sub to create a pressure differential across the valve to move the valve toward the low pressure side, while the port remains closed by the valve, thereafter reducing pressure within the sub to reduce the pressure differential and driving the valve to move it away from a position covering the port.Type: GrantFiled: October 28, 2010Date of Patent: June 24, 2014Assignee: Packers Plus Energy Services Inc.Inventors: Daniel Jon Themig, Kevin O. Trahan, Christopher Denis Desranleau, Frank DeLucia

Patent number: 8757274Abstract: A well tool actuator can include a series of chambers which, when opened in succession, cause the well tool to be alternately actuated. A method of operating a well tool actuator can include manipulating an object in a wellbore; a sensor of the actuator detecting the object manipulation; and the actuator actuating in response to the sensor detecting the object manipulation. A drilling isolation valve can comprise an actuator including a series of chambers which, when opened in succession, cause the isolation valve to be alternately opened and closed. A method of operating a drilling isolation valve can include manipulating an object in a wellbore, a sensor of the drilling isolation valve detecting the object manipulation, and the drilling isolation valve operating between open and closed configurations in response to the sensor detecting the object manipulation.Type: GrantFiled: June 7, 2012Date of Patent: June 24, 2014Assignee: Halliburton Energy Services, Inc.Inventors: Neal G. Skinner, Michael L. Fripp

Patent number: 8752629Abstract: A valve assembly for regulating fluid flow in a horizontal wellbore. A housing can be coupled to a production tubular. A chamber is defined within the housing and can be in fluid communication through a flow channel with an inner annulus formed adjacent the wellbore. A piston and a biasing member can be disposed within the chamber, where the biasing member biases the piston into a first position. A flowpath is defined within the housing and communicable with both the production tubular and the inner annulus. The flowpath can include one or more nozzles disposed therein, and the piston can be configured to move between the first position allowing fluid flow through the flowpath to the production tubular and a second position preventing fluid flow to the production tubular.Type: GrantFiled: February 4, 2011Date of Patent: June 17, 2014Assignee: Schlumberger Technology CorporationInventor: Terje Moen

Patent number: 8746343Abstract: A tubing string assembly is disclosed for fluid treatment of a wellbore. The tubing string can be used for staged wellbore fluid treatment where a selected segment of the wellbore is treated, while other segments are sealed off. The tubing string can also be used where a ported tubing string is required to be run in a pressure tight condition and later is needed to be in an open-port condition.Type: GrantFiled: September 12, 2012Date of Patent: June 10, 2014Assignee: Packers Plus Energy Services Inc.Inventors: Jim Fehr, Daniel Jon Themig
