Filed:

Appl. No.:

13/087635

Inventors:

Cesar G. Garcia - Katy TX, US
Patrick J. Zimmerman - Houston TX, US

Antonio B. Flores - Houston TX, US
Michael Dedman - Powell WY, US

Assignee:

Weatherford/Lamb, Inc. - Houston TX

International Classification:

E21B 34/06
E21B 34/14

US Classification:

166373, 166386, 166194, 166318

Abstract:

A downhole sleeve has an insert movable in the sleeve's bore from a closed condition to an opened condition when a ball dropped in the bore engages an indexing seat in the sliding sleeve. In the closed condition, the insert prevents communication between the bore and the sleeve's port, while the insert in the opened condition permits communication between the bore and port. Keys of a seat extend into the bore to engage the ball and to move the insert open. After opening, the keys retract so the ball can pass through the sleeve to another cluster sleeve or to an isolation sleeve of an assembly. Insets or buttons disposed in the sleeve's port temporarily maintain fluid pressure in the sleeve's bore so that a cluster of sleeves can be opened before treatment fluid dislodges the button to treat the surrounding formation through the open port.

International Classification:

E21B 33/12
E21B 34/00

US Classification:

166386, 166318

Abstract:

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.

Appl. No.:

Inventors:

Antonio B. Flores - Houston TX, US
David Ward - Houston TX, US
Cesar G. Garcia - Katy TX, US

Assignee:

Weatherford/Lamb, Inc. - Houston TX

International Classification:

E21B 23/02
E21B 34/06

US Classification:

166373, 166194

Abstract:

A system of sliding valves wherein the inserts of multiple sliding valves may be shifted to an open position using a single shifting ball. Each individual sliding valve has a movable insert that, depending upon the position of the insert within the sliding valve, may either block or permit fluid to radially flow between the interior and exterior of the sliding valve. The insert has a profile about the interior of the movable insert allowing a shifting tool to connect to and move the insert so that fluid may be prevented from entering the interior portion of the sliding sleeve.

Assignee:

WEATHERFORD/LAMB, INC. - Houston TX

International Classification:

E21B 34/06

US Classification:

166373, 166318

Abstract:

A device to allow a single ball size to actuate at least two downhole tools. Typically when a large number of ball actuated devices are run in a single well the total number of devices is limited by the increasing size of the balls required to actuate each sequential device. By having a mechanism that allows at least two tools to be actuated by each ball size the total number of ball actuated devices may be at least doubled.

International Classification:

E21B 33/129
E21B 33/128

Abstract:

A downhole tool with a radially expandable sealing element, such as a packer or plug. The sealing element employs metallic support rings disposed on the sealing element outer surface for preventing extrusion during run-in and for clamping the sealing element to the tool.

Dick S. Gonzalez - Houston TX, US

International Classification:

E21B 34/14
E21B 34/10
E21B 43/14

Abstract:

A completion apparatus for a wellbore includes several flow tools and an actuation mechanism. The flow tools have a piston defining first and second chambers with a housing. The chambers communicate with hydraulics so the piston are movable in response to the communicated hydraulics. A sleeve disposed in the housing is movable with the piston between first, second, and third positions. The sleeve can have a seat movable between two conditions for passing/engaging plugs. The sleeve in the first position closes off communication through the first and second ports, and the sleeve in the second position permits communication through the first port and closes off communication through the second port. The sleeve in the third position closes off communication through the first port and permits communication through the second port. The actuation mechanism is operable to communicate the hydraulics respectively with the chambers of the flow tools.
