| 20090038796 | Expandable leak path preventer in fluid activated downhole tools - Expandable seal members or inserts are included as part of fluid activated downhole tools such as packers and liner hangers. The expandable seal inserts comprise one or more expandable materials that expand and seal against the chamber carrying the actuator of the downhole tool. Fluid flowing in the downhole tool to actuate and, thus, set the downhole tool, also causes the expandable seal inserts to expand. In so doing, the expandable seal inserts provide seals, some redundant to dynamic seals and static seals already present in the downhole tool, to assist in preventing leaks in the downhole tool that may otherwise cause the downhole tool to fail. | 02-12-2009 |
| 20090044946 | Ball seat having fluid activated ball support - Apparatuses for closing a well conduit comprise a housing having a longitudinal bore and a seat disposed within the bore. A chamber is disposed within the housing and includes a plug element support member, such as ram or piston, operatively associated within the chamber. The plug element support member has a retracted position and an extended position. A passageway is in fluid communication with the bore and the chamber. A plug element such as a ball or drop plug, is adapted to be disposed into the bore and landed on the seat to restrict fluid flow through the bore and the well conduit. Landing the plug element causes and allowing fluid pressure to build causes the plug element support member to move from the retracted position to the extended position to provide support to the plug element landed on the seat. | 02-19-2009 |
| 20090044948 | Ball seat having ball support member - Apparatuses for restricting fluid flow through a well conduit comprise a housing having a longitudinal bore and a seat disposed within the bore. The seat has a first position when the apparatus is in the run-in position and a second position when the apparatus is in the set position. A plug element support member has a retracted position when the apparatus is in the run-in position and an extended position when the apparatus is in the set position. A plug element adapted to be disposed into the bore and landed on the seat to restrict fluid flow through the bore and the well conduit is used to move the plug element support member from the retracted position to the extended position, thereby providing support to the plug member landed on the seat. | 02-19-2009 |
| 20090044949 | Deformable ball seat - Apparatuses for restricting fluid flow through a well conduit comprise a housing having a longitudinal bore and a collapsible seat disposed within the bore. The seat has a first position defining a first seat inner diameter when the apparatus is in the run-in position and a second position defining a second seat inner diameter when the apparatus is in the set position. The first seat inner diameter is greater than the second seat inner diameter. A plug element is adapted to be disposed into the bore and landed on the seat to move the seat from the first position to the second position. While in the second position, the seat restricts fluid flow through the bore and provides additional support to the plug member landed on the seat. | 02-19-2009 |
| 20090044955 | Reusable ball seat having ball support member - Apparatuses for restricting fluid flow through a well conduit comprise a housing having a longitudinal bore and a reusable seat disposed within the bore. The seat comprises a slidable element, a fixed element, a plug element support member, a seat inner diameter, and a return member to urge the slidable element toward the run-in position. The plug element support member has a retracted position when the seat is in the run-in position and an extended position when the seat is in the set position. A plug element adapted to be disposed into the bore and landed on the seat to restrict fluid flow through the bore and the well conduit is used to move the plug element support member from the retracted position to the extended position, thereby providing support to the plug element landed on the seat. | 02-19-2009 |
| 20090126947 | SWELLABLE MATERIAL AND METHOD - A swellable material seal includes a quantity of swellable material disposed in a geometric configuration; and a plurality of openings in the material to enhance wettability thereof by a swelling fluid and method. | 05-21-2009 |
| 20090159289 | Ball seat having segmented arcuate ball support member - Apparatuses for restricting fluid flow through a well conduit comprise a housing having a longitudinal bore and a seat disposed within the bore. The seat has a first position when the apparatus is in the run-in position and a second position when the apparatus is in the set position. The seat comprises an arcuate member comprising a plurality of slits defining a plurality of segment members having a gap there-between. Each of the gaps are variable such that movement of segment members inwardly causes the gaps to be narrowed or closed off completely when a plug element is disposed into the bore and landed on the arcuate member to move the arcuate member from the first position to the second position, causing restriction of fluid flow through the bore and the well conduit. | 06-25-2009 |
| 20090229832 | Pressure Compensator for Hydrostatically-Actuated Packers - Devices and methods for operating a tool within a wellbore. A downhole tool includes a tool operation portion having a moveable tool member and a setting portion having a setting piston and setting chamber. A fluid pressure compensation reservoir is in fluid communication with the setting chamber and containing a pressurized fluid which offsets external hydrostatic pressure. | 09-17-2009 |
| 20100243276 | DOWNHOLE SWELLABLE SEALING SYSTEM AND METHOD - Disclosed herein is a downhole tubular sealing system. The system includes, a tubular runnable in a downhole wellbore, a swellable seal disposed at the tubular that is sealable with the downhole wellbore when swelled, and at least one releasable member in operable communication with the tubular and the swellable seal. The at least one releasable member configured to longitudinally fix the swellable seal to the tubular when nonreleased and to longitudinally disengage the swellable seal from the tubular when released. | 09-30-2010 |
| 20110030976 | TUBULAR ACTUATOR, SYSTEM AND METHOD - A tubular actuating system includes, a tubular, a plurality of same plugs runnable within the tubular, a sleeve disposed at the tubular, and at least one slide that is movably disposed at the sleeve between at least a first position and a second position, the at least one slide is configured to be seatingly engagable with a first of the plurality of same plugs when in the first position and seatingly engagable with a second of the plurality of same plugs when in the second position. | 02-10-2011 |
| 20110100647 | Tubular Actuator, System and Method - A tubular actuating system includes a tubular, a plurality of same plugs runnable within the tubular, an actuator disposed within the tubular, and a seatable member disposed at the actuator configured to be respositionable relative to the actuator between an unseated position and a seated position upon passage of at least one of the plurality of same plugs. | 05-05-2011 |
| 20110101628 | SWELLABLE MATERIAL AND METHOD - A swellable material seal includes a quantity of swellable material disposed in a geometric configuration; and a plurality of openings in the material to enhance wettability thereof by a swelling fluid. | 05-05-2011 |
