20150144374 | VARYING RADIAL ORIENTATION OF A POWER CABLE ALONG THE LENGTH OF AN UMBILICAL - A power triad of an umbilical may be rotated during multiple transition lengths to position each power cable of the power triad equally at radial orientation over the length of the umbilical. A first portion of the umbilical includes the triad in a first radial orientation, a second portion of the umbilical includes the triad in a second radial orientation, and a third portion of the umbilical includes the triad in a third radial orientation. The triad is rotated a first one hundred twenty degrees from the first radial orientation to the second radial orientation during a first transition length. The triad is rotated a second one hundred twenty degrees from the second radial orientation to the third radial orientation during a second transition length. The use of three radial orientations along the length of the umbilical may reduce imbalances between the power cables of the triad. | 05-28-2015 |

20100132956 | EXPANDABLE CONNECTION WITH METAL TO METAL SEAL - An expandable tubular connection includes coupled first and second tubular members and a sealing end on one of the first and second tubular members engaged with an angled shoulder coupled to the other of the first and second tubular members, wherein the sealing end deflects on the angled shoulder and plastically deforms into one of the first and second tubular members upon radial expansion and plastic deformation of the expandable tubular connection. A tubular sleeve including the angled shoulder may be coupled between the first and second tubular members. The sealing end may have an inner radial projection that is deflected into a surface on the first tubular member. A method includes pre-loading a sealing end of the second tubular member onto an angled shoulder of the tubular sleeve, radially expanding and plastically deforming the tubular connection, and deflecting the sealing end on the angled shoulder and into the first tubular member. | 06-03-2010 |

20120152565 | DOWNHOLE RELEASE JOINT WITH RADIALLY EXPANDABLE MEMBER - A downhole releasable tubular connection includes a joint between two tubing strings, wherein one of the two tubing strings is radially expanded and plastically deformed by an expansion device. When the expansion device is moved adjacent to the joint, a threaded connection mechanism in the joint reacts to the radially outward forces of the expansion device and releasably expands, thereby decoupling the tubing strings. | 06-21-2012 |
20120152567 | DOWNHOLE RELEASE JOINT WITH RADIALLY EXPANDABLE MEMBER - An apparatus comprises an expansion device that is coupled to a support member and operable to be disposed within a tubular member. The expansion device is operable to radially expand the tubular member as the expansion device moves axially through the tubular member. A latch assembly is coupled to the support member and is operable to engage a corresponding latch receptacle disposed within the tubular member so as to limit the axial movement of the expansion device relative to the tubular member | 06-21-2012 |

20150315901 | PLUG FOR DOWNHOLE LOGGING TOOL - A plug for use in a downhole tool collar allows a seal between the inside and outside of the collar. The plug provides an electromagnetically transparent window through which the signals from the measurement device may propagate to or from the surrounding formation. The plug assembly includes an inner retainer, an outer retainer, and a plug. The inner retainer may be inserted into the inside of a slot formed in the collar. The inner retainer may have a concave inner surface to match the cylindrical inner surface of the collar. Likewise, the outer collar may be inserted into the outside of the slot, and may have a convex outer surface to match the cylindrical outer surface of the collar. The plug may fit into slots in the inner and outer retainers and be held in place within the slot. | 11-05-2015 |

20120097391 | EXPANDABLE CASING PATCH - A system comprising a housing having an upper end in fluid communication with a source of pressurized fluid and a lower end releasably coupled to an expandable tubular. A piston is disposed within and sealingly engaged with the housing. An expansion cone is coupled to the piston and is operable to radially expand the expandable tubular as it moves longitudinally therethrough. A pressure chamber is disposed within the housing and defined by the piston and the expansion cone. A first pressure relief port is disposed within the housing and is operable to allow fluid communication between the pressure chamber and an annulus external to the housing. A second pressure relief port is disposed within the expansion cone and is operable to allow fluid communication between the pressure chamber and a portion of the expandable tubular below the expansion cone. | 04-26-2012 |

20100044030 | Geometrically Optimized Expansion Cone - A geometrically optimized expansion cone for radially expanding a tubular member. In some embodiments, the expansion cone includes an annular body having an outer surface. The outer surface includes a linear surface having a constant diameter, a curvilinear surface extending from the linear surface, a recessed surface having a diameter less than the diameter of the curvilinear surface, and a chamfer between the recessed surface and the curvilinear surface. The diameter of the linear surface is substantially equal to an inner diameter of the tubular member after expansion, while the chamfer has a maximum diameter less than an inner diameter of the tubular member prior to expansion. The curvilinear surface has a diameter defined by a radius of curvature which is tangent to the chamfer at the maximum diameter and tangent to the linear surface. | 02-25-2010 |
20110094753 | DOWNHOLE RELEASE JOINT WITH RADIALLY EXPANDABLE MEMBERS - A downhole releasable tubing connection includes a joint between two tubing strings, wherein one of the two tubing strings is radially expanded and plastically deformed by an expansion device. When the expansion device is moved adjacent to the joint, a mechanism in the joint reacts to the radially outward forces of the expansion device and releasably expands, separates, breaks, or otherwise provides a release between the two tubing strings. One tubing string and the expansion device can then be removed to the surface of the well bore while the expanded tubing remains installed in the well bore. | 04-28-2011 |
20120273231 | DOWNHOLE RELEASE JOINT - An apparatus comprises a support member operable to be disposed within a tubular member that includes a threaded connection with a pin member. The tubular member is coupled to an expansion device that is operable to radially expand the tubular member and a pin catcher that is operable to engage the pin member as the expansion device and pin catcher move axially through the tubular member. | 11-01-2012 |
20130000924 | EXPANDABLE LINER SYSTEM - A system comprises a tubular releasably coupled to a launcher. An expansion assembly is sealingly engaged with the tubular so that the expansion assembly is moved longitudinally through the tubular by applying a pressurized fluid to the launcher. The expansion assembly radially expands the tubular as it moves longitudinally therethrough. A valve is coupled to the expansion assembly and opens when fluid pressure within an unexpanded portion of the tubular exceeds fluid pressure within the launcher. An extending member is coupled to the expansion assembly and to the launcher. The extending member restricts longitudinal movement of the expansion assembly relative to the launcher once the tubular is radially expanded. | 01-03-2013 |
