Patent number: 9909394Abstract: A gripper assembly for gripping coiled tubing with lower and upper ball carriers. A first gripper portion and a second gripper portion each have a channel for a bore through the gripper portions. Gripper portions can rotate in relation to each other. Rotation causes the gripper portion to close around an object that passes through the bore. With a translational force, the gripper portions rotate relative to each other to grasp an object.Type: GrantFiled: May 20, 2015Date of Patent: March 6, 2018Assignee: Subsea Technology, Inc.Inventor: David G. Hosie

Patent number: 7475732Abstract: The present generally relates to apparatus and methods for instrumentation associated with a downhole deployment valve or a separate instrumentation sub. In one aspect, a DDV in a casing string is closed in order to isolate an upper section of a wellbore from a lower section. Thereafter, a pressure differential above and below the closed valve is measured by downhole instrumentation to facilitate the opening of the valve. In another aspect, the instrumentation in the DDV includes sensors placed above and below a flapper portion of the valve. The pressure differential is communicated to the surface of the well for use in determining what amount of pressurization is needed in the upper portion to safely and effectively open the valve. Additionally, instrumentation associated with the DDV can include pressure, temperature, seismic, acoustic, and proximity sensors to facilitate the use of not only the DDV but also telemetry tools.Type: GrantFiled: May 3, 2007Date of Patent: January 13, 2009Assignee: Weatherford/Lamb, Inc.Inventors: David G.

Patent number: 6209663Abstract: Apparatus and methods for a deployment valve used with an underbalanced drilling system to enhance the advantages of underbalanced drilling. The underbalanced drilling system may typically comprise elements such as a rotating blow out preventer and drilling recovery system. The deployment valve is positioned in a tubular string, such as casing, at a well bore depth at or preferably substantially below the string light point of the drilling string. When the drilling string is above the string light point then the upwardly acting forces on the drilling string become greater than downwardly acting forces such that the drilling string begins to accelerate upwardly. The deployment valve has a bore sufficiently large to allow passage of the drill bit therethrough in the open position. The deployment valve may be closed when the drill string is pulled within the casing as may be necessary to service the drill string after drilling into a reservoir having a reservoir pressure.Type: GrantFiled: April 14, 1999Date of Patent: April 3, 2001Inventor: David G.

Patent number: 6129152Abstract: A rotating blowout preventer and method is disclosed that includes a flexible bladder that defines a pressure chamber radially outwardly of the bladder for direct activation of the bladder to allow for gas tight sealing along the variable profile of drill pipe and the irregular shape of the kelly. The pressure chamber for activating the bladder is preferably defined within the rotating seal assembly. As well, the rotating seal assembly includes both the bladder and the bearings. A pressure drop element is included within the hydraulic flow line through the rotating seal assembly so that the upper seal and bearing have a significantly reduced pressure drop for increased lifetime operation. The rotating seal assembly is hydraulically secured within the rotating blow-out preventer housing, preferably by remote control, by means of a preferred single cylindrical latch piston that moves upwardly and downwardly substantially parallel to the well bore axis.Type: GrantFiled: October 23, 1998Date of Patent: October 10, 2000Assignee: Alpine Oil Services Inc.Inventors: David G. Hosie, Michael B. Grayson

Patent number: 6082707Abstract: Apparatus and methods are disclosed for a valve seat wherein the geometry of the seat is such that the resultant axial forces due to the differential between internal and external pressure across the valve seat result in a resultant axial force that urges the valve seat into sealing engagement with the plug or other type of closure member, regardless of the direction of the differential pressure. Thus the valve seat is urged against the closure member regardless of whether the line pressure or bonnet pressure is higher. In the same manner, a resultant axial force urges a seal seat of the preferred embodiment into sealing engagement with the valve body. An axially moveable seal bearing ring is positioned between the valve seat and the seal seat that alters the effective geometry of the seat elements when it moves between a first position and a second position. The seal bearing ring moves responsively to the direction of the differential pressure across the seat elements.Type: GrantFiled: October 23, 1998Date of Patent: July 4, 2000Assignee: Gulf Technologies International, L.C.Inventors: David G. Hosie, Michael B. Grayson, David G. Ward

Patent number: 6059262Abstract: The valve operator of the present invention provides an apparatus and method for reducing torque necessary for opening and closing a valve, such as a quarter-turn rotary valve. In the preferred embodiment, an outer handle adaptor has inner curved tracks that drive balls positioned in straight slots of a middle cylinder. As the balls move in the straight slots, they transfer torque energy to a valve shaft adaptor mounted within the middle cylinder and having outer curved threads that mesh with the balls. The pitch of the curved tracks of the outer handle differ from the pitch the curved tracks of the valve shaft adaptor to thereby effect a desired torque reduction ratio. The valve operator has relatively few components, at least three or more relatively rotatable components, preferably arranged in meshing configuration so as to effect a small size operator without the use of a gear box.Type: GrantFiled: October 23, 1998Date of Patent: May 9, 2000Assignee: Gulf Technologies International, L.C.Inventors: David G. Hosie, Michael B. Grayson, David G. Ward

Patent number: 5603384Abstract: A firing head for actuating an explosive charge in a perforating gun. A firing pin is positioned within the firing head housing to actuate a booster charge leading to the perforating gun. The firing pin can be actuated by mechanical techniques, by controlling the differential pressure between the housing pressure and the well pressure, and by controlling the absolute fluid pressure inside the housing. A release pin initially secures the firing pin, and the release pin can be mechanically actuated. The release pin is also releasably engaged with a differential piston that communicates with the well pressure through a port in the firing head housing. Increases in the housing fluid pressure moves the piston and attached release pin to release the firing pin into contact with the booster charge. Alternatively, the port can be plugged to permit absolute pressure actuation of the firing pin.Type: GrantFiled: October 11, 1995Date of Patent: February 18, 1997Assignee: Western Atlas International, Inc.Inventors: Robert K.
