Irregularly Shaped Flapper Closure and Sealing Surfaces

Номер: US20120012202A1
Принадлежит: Weatherford Lamb Inc

A flapper valve for a surface controlled, sub-surface safety valve has a seat and a curved flapper. The seat has a seating rim, and the curved flapper has a sealing rim and can pivot relative to the seat. The flapper's sealing rim corresponds in shape to the seating rim. Both rims have lobes disposed outside a circular perimeter. Also, the undulating edges of the rims have corresponding outcroppings and incroppings. When a flow tube moves towards or away from the flapper, the flapper's lobes protect the flapper's sealing rim as the flapper's inside surface engages the moving flow tube. Moreover, the rims can have a groove and a ridge that engage one another when the rims close.

Arrangement of Isolation Sleeve and Cluster Sleeves Having Pressure Chambers

Номер: US20120055684A1
Принадлежит: Weatherford Lamb Inc

For wellbore fluid treatment, sliding sleeves deploy on tubing in a wellbore annulus. Operators deploy a plug down the tubing to a first sleeve. The plug seats in this first sleeve, and pumped fluid pressure opens the first sleeve and communicates from the tubing to the wellbore annulus. In the annulus, the fluid pressure creates a pressure differential between the wellbore annulus pressure and a pressure chamber on second sleeves on the tubing. The resulting pressure differential opens the second sleeves so that fluid pressure from the tubing can communicate through the second open sleeves. Using this arrangement, one sleeve can be opened in a cluster of sleeves without opening all of them at the same time. The deployed plug is only required to open the fluid pressure to the annulus by opening the first sleeve. The pressure chambers actuate the second sleeves to open up the tubing to the annulus.

A self piloted check valve which utilizes closure of a piloting flapper valve to permit development of closure forces for a ball valve. The normally open ball valve has a central flow passage and simultaneously rotates and translates as it traverses between its fully open and fully closed positions. An opening bias system utilizes a combination of a first less stiff spring and a second stiffer spring. Reversible decoupling means disconnects and reconnects the second spring at a short travel distance from the normally open position of the ball, white the first spring always provides opening bias forces to the ball. The pressure induced force required to fully close the ball valve following decoupling of the second spring is more than the force required to overcome the combination of the first and second springs.

Method and Apparatus for Treating a Well

Номер: US20140060830A1
Автор: Douglas N. Love
Принадлежит: Texian Resources

A method for treating a well includes positioning a seat within the well that is capable of catching an obstruction which will prevent flow of fluid downstream of the seat. According to one embodiment of the invention, the seat is formed by expanding a sleeve with a ring positioned around its periphery or as a subsequent step in the process. As the sleeve is expanded over the ring, the seat is formed. Once the seat is formed, an obstruction in the form of a ball or dart is dropped down to the seat. In another embodiment the sleeve acts as a stop for a secondary valve seat which catches the obstruction. The casing uphole of the seat is perforated so that fluid under pressure will enter the formation surrounding the perforations. The process is particularly useful for fracing a formation in a horizontal well where numerous stages are required to complete the stimulation of the well. There is also potential application in vertical wells.

Downhole shutoff tool

Номер: US20140069655A1
Автор: Larry Rayner Russell
Принадлежит: Individual

A downhole drilling valve tool, positioned above the drill bit, which utilizes a ball valve having a through bore for normal flow. The ball valve is operated bidirectionally by a piston driven mechanism between an open position and a closed position. The piston mechanism is responsive to a reference accumulator pressure on a first side and the pressure in the apparatus bore above the ball valve on a second side. Whenever the valve apparatus is lowered at least a minimum distance into the well bore, a pressure relief valve is used to maintain a fixed margin between the flowing bore pressure and the accumulator pressure. Closure of the ball valve occurs when the accumulator pressure exceeds the bore pressure during pump stoppages. The downhole drilling valve tool offers a more wear resistant sealing means, as well as higher pressure operability than conventional downhole check valves.

Mechanically actuated device positioned below mechanically actuated release assembly utilizing j- slot device

Номер: US20150041141A1
Автор: Arthur Stautzenberger
Принадлежит: Halliburton Energy Services Inc

A tool string carrying an external tool, such as a liner hanger, on a release mechanism is lowered into the wellbore. Interlocking lugs and J-slot profile, defined between the exterior surface of the mandrel and interior surface of the release mechanism, allow relative movement of release mechanism and mandrel without releasing the release mechanism. The relative movement allows mechanical operation of a valve or other tool positioned below the release mechanism. Weight-down and rotation of the tool string and mandrel actuates the lower valve assembly by turning a sleeve into alignment with cooperating members of the mandrel. The sleeve, no longer constrained, moves longitudinally in response to a biasing mechanism. Movement of the sleeve allows closure of the valve. After actuation of the valve tool, further weight-down releases the release mechanism from the carried tool.
