20110192613 | Cluster Opening Sleeves for Wellbore - 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. | 08-11-2011 |
20120055684 | Arrangement of Isolation Sleeve and Cluster Sleeves Having Pressure Chambers - 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. | 03-08-2012 |
20120305265 | Cluster Opening Sleeves for Wellbore - 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. | 12-06-2012 |
20130043042 | Multiple Shift Sliding Sleeve - 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. | 02-21-2013 |
20130192846 | Resettable Ball Seat - 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. | 08-01-2013 |
20140166292 | Sliding Sleeve Having Deformable Ball Seat - A sliding sleeve opens with a deployed ball. The sleeve has a seat disposed in the housing, and the seat has segments biased outward from one another with a C-ring or other biasing element. Initially, the seat has an expanded state in the sliding sleeve so that the seats segments expand outward against the housing's bore. When an appropriately sized ball is deployed downhole, the ball engages the expanded seat. Fluid pressure applied against the seated ball moves the seat into the inner sleeve's bore. As this occurs, the seat contracts, which increases the engagement area of the seat with the ball. Eventually, the seat reaches the shoulder in the inner sleeve so that pressure applied against the seated ball now moves the inner sleeve in the housing to open the sliding sleeve's flow port. | 06-19-2014 |
20140166303 | Sliding Sleeve Having Contracting, Ringed Ball Seat - A sliding sleeve opens with a deployed ball. The sleeve has a seat disposed in the housing, and the seat has segments biased outward from one another with a C-ring or other biasing element. Initially, the seat has an expanded state in the sliding sleeve so that the seats segments expand outward against the housing's bore. When an appropriately sized ball is deployed downhole, the ball engages the expanded seat. Fluid pressure applied against the seated ball moves the seat into the inner sleeve's bore. As this occurs, the seat contracts, which increases the engagement area of the seat with the ball. Eventually, the seat reaches the shoulder in the inner sleeve so that pressure applied against the seated ball now moves the inner sleeve in the housing to open the sliding sleeve's flow port. | 06-19-2014 |
20140251594 | Millable Fracture Balls Composed of Metal - A ball is used for engaging in a downhole seat and can be milled out after use. The ball has a spherical body with an outer surface. An interior of the spherical body is composed of a metallic material, such as aluminum. The spherical body has a plurality of holes formed therein. The holes extend from at least one common vertex point on the outer surface of the spherical body and extend at angles partially into the interior of the spherical body. | 09-11-2014 |
20140251628 | Anti-Rotation Assembly for Sliding Sleeve - A sliding sleeve has an inner sleeve that moves in a housing. For example, the inner sleeve can move open relative to a port in the housing when a deployed ball engages a seat in the inner sleeve. Because the seat and the ball (if remaining) are preferably milled out of the inner sleeve after use, the inner sleeve preferably does not rotate in the housing during milling operations. To accomplish this, an anti-rotation clutch assembly in the sliding sleeve helps prevent the inner sleeve from rotating. A wedged cone is formed on a distal end of the inner sleeve and press fits into a cupped shoulder on the inside of the sleeve's housing. | 09-11-2014 |
