| 20110290476 | WELL ASSEMBLY COUPLING - Assemblies that can be disposed in a subterranean bore and that can facilitate branch wellbore creation are described. An assembly can include threadedly coupled components having inner and outer sealing members in grooves. The sealing member can cooperate with the components to provide a pressure seal. The assembly can also include a venting member for equalizing pressure in a chamber defined by the coupled components. One of the components can be made from aluminum. At least part of that component can be coated with a coating material that is nonconductive. | 12-01-2011 |
| 20120111636 | COMBINATION WHIPSTOCK AND COMPLETION DEFLECTOR - Assemblies can be disposed in a subterranean bore. An assembly can include a surface that can divert a cutting tool for creating a branch wellbore and that can divert a completion component for completing the branch wellbore without requiring the assembly or part of the assembly from being removed from a parent wellbore prior to the completion component being diverted. | 05-10-2012 |

| 20140144617 | System for Circumferentially Aligning a Downhole Latch Subsystem - A system for circumferentially aligning a downhole latch subsystem in a wellbore. The system includes an outer tool assembly including a latch coupling having a latch profile and a slot subassembly having an axially extending slot profile. An inner tool assembly is positionable within the outer tool assembly. The inner tool assembly includes a latch assembly having a plurality of latch keys and an orienting subassembly having a plurality orienting keys. In operation, after axial alignment of the orienting subassembly with the slot subassembly, rotation of the orienting subassembly causes operable engagement of at least one orienting key with the slot profile and, thereafter, axial alignment of the latch assembly with the latch coupling causes operable engagement of the latch keys with the latch profile. | 05-29-2014 |
| 20140144652 | Apparatus, System and Method for Circumferentially Orienting a Downhole Latch Subsystem - An apparatus for circumferentially orienting a downhole latch assembly in a wellbore. The downhole latch assembly has a plurality of latch keys including a primary latch key. The apparatus includes a casing string positionable in the wellbore. A window joint is interconnected in the casing string. A latch coupling having a latch profile is interconnected in the casing string downhole of the window joint. An orienting subassembly interconnected in the casing string has an orienting profile positioned uphole of the latch profile such that, after operable engagement of the primary latch key with the orienting profile, axial alignment of the latch assembly with the latch coupling causes operable engagement of the latch keys with the latch profile. | 05-29-2014 |
| 20140178235 | ELECTROFORMED STATOR TUBE FOR A PROGRESSING CAVITY APPARATUS - A method for use in producing a stator for a progressing cavity apparatus which includes the use of electroforming to produce the stator tube. A stator tube for a progressing cavity apparatus which is produced using electroforming and a stator for a progressing cavity apparatus which includes a stator tube produced using electroforming. | 06-26-2014 |
| 20150060049 | Retractable Collet Assembly for Liner String Installation in a Wellbore - A collet assembly for installing a liner string having a profile in a wellbore. The collet assembly has a generally cylindrical collet collar with a plurality of collet fingers extending therefrom each having a collet head on a distal end thereof. In a first position, the collet fingers are in a radially outwardly flexed state such that the collet finger extend substantially parallel with the central axis of the collet collar. In a second position, the collet fingers are in a radially relaxed state such that the collet fingers extend from the collet collar to the collet heads at an angle toward the central axis of the collet collar. | 03-05-2015 |
| 20150060086 | Running Tool with Retractable Collet for Liner String Installation in a Wellbore - A running tool for installing a liner string having a profile in a wellbore. The running tool includes a mandrel, a prop assembly positioned about the mandrel and a collet assembly slidably positioned on the mandrel. The collet assembly has a generally cylindrical collet collar with a plurality of collet fingers extending therefrom each having a collet head on a distal end thereof. In a first position, the prop assembly radially outwardly flexes the collet fingers such that the collet heads engage the profile of the liner string and are operable to apply a force in the downhole direction to the liner string. In a second position, the collet assembly is remote from the prop assembly such that the collet fingers radially inwardly contract disengaging the collet heads from the profile of the liner string, thereby enabling removal of the running tool from the liner string. | 03-05-2015 |
| 20150083410 | Wiper Plug for Determining the Orientation of a Casing String in a Wellbore - A system for determining the orientation of a casing string in a wellbore. The system includes a downhole tool disposed interiorly of the casing string in a known orientation relative to at least one feature of the casing string. A sensor module is operably associated with the downhole tool and is configured to obtain data relating to the orientation of the casing string. A communication module is operably associated with the sensor module. The communication module is configured to transmit information to a surface location, wherein, the information corresponds to the data obtained by the sensor module relating to the orientation of the casing string. | 03-26-2015 |
