Patent number: 11326403Abstract: A rotating control device can include a latch assembly with a lock ring that permits displacement of an inner mandrel in one longitudinal direction, and prevents displacement of the inner mandrel in an opposite longitudinal direction. Another rotating control device can include a latch assembly and an equalization valve having an open configuration in which fluid communication is permitted between an exterior and an interior of the rotating control device through the equalization valve, the latch assembly changing from a latched to an unlatched configuration only when the equalization valve is in the open configuration. A method of installing a rotating control device can include releasing a running tool from the rotating control device by producing relative rotation between components of the running tool.Type: GrantFiled: March 31, 2021Date of Patent: May 10, 2022Assignee: Weatherford Technology Holdings, LLCInventors: Danny W.

Patent number: 9932786Abstract: The exemplary embodiments relate to misalignment correction devices and methods for mitigating misalignment of a piece of oilfield equipment in or proximate an RCD. A rounded shoulder appears on a first surface within or proximate the RCD, and a socket profile appears on a second surface within or proximate the RCD. The second surface is configured to abut the rounded shoulder. The rounded shoulder is configured to rotate within the socket profile. Further, a floating joint may be implemented into or proximate the RCD and combined with the foregoing rotation mitigation features.Type: GrantFiled: May 29, 2015Date of Patent: April 3, 2018Assignee: Weatherford Technology Holdings, LLCInventors: James W.

Patent number: 9784073Abstract: A system and method is provided for converting a drilling rig between conventional hydrostatic pressure drilling and managed pressure drilling or underbalanced drilling using a docking station housing mounted on a marine riser or bell nipple. This docking station housing may be positioned above the surface of the water. When a removable rotating control device is remotely hydraulically latched with the docking station housing, the system and method allows for interactive lubrication and cooling of the rotating control device, as needed, along with a supply of fluid for use with active seals.Type: GrantFiled: January 26, 2015Date of Patent: October 10, 2017Assignee: Weatherford Technology Holdings, LLCInventors: Thomas F.

Publication number: 20150027688Abstract: A system and method is provided for a low profile rotating control device (LP-RCD) and its housing mounted on or integral with an annular blowout preventer seal, casing, or other housing. The LP-RCD and LP-RCD housing can fit within a limited space available on drilling rigs. An embodiment allows a LP-RCD to be removably disposed with a LP-RCD housing by rotating a bearing assembly rotating plate. A sealing element may be removably disposed with the LP-RCD bearing assembly by rotating a seal retainer ring. Alternatively, a sealing element may be removably disposed with the LP-RCD bearing assembly with a seal support member threadedly attached with the LP-RCD bearing assembly. The seal support member may be locked in position with a seal locking ring removably attached with threads with the LP-RCD bearing assembly over the seal support member. Spaced apart accumulators may be disposed radially outward of the bearings in the bearing assembly to provide self lubrication to the bearings.Type: ApplicationFiled: September 25, 2014Publication date: January 29, 2015Applicant: Weatherford/Lamb, Inc.Inventors: Jonathan P.
