Abstract: 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.

Abstract: A sealing assembly for sealing against a piece of oilfield equipment in a wellbore. The sealing assembly has a support housing and the support housing defines an inner wall and a port configured for fluid communication with the wellbore. Such inner wall defines a stop shoulder, and the support housing has a limit structure proximate one or both end(s). A sealing element is contained within the support housing. A ring is connected to the sealing element at one or both end(s). Each ring is configured for slidable movement along the inner wall of the support housing and further configured to float between the stop shoulder and the limit structure.

Abstract: An annular seal having a sealing member and method for use is provided for sealing an item of oilfield equipment. The annular seal has an inner diameter for receiving the item of oilfield equipment and a frame. The seal member is contiguous with the frame. The annular seal is configured for durability, in that it resists wear, inversion, increases lubricity, enables tightness, and/or otherwise generally increases endurance, toughness, and/or permanence.

Non-contact (position), contact (on/off and/or position) and hydraulic (flowmeter), both direct and indirect, embodiments include fluid measurement systems, an electrical switch system, a mechanical valve system, and proximity sensor systems.

Abstract: Rotating control device related oilfield pressure control is accomplished by upper and lower seal members configured to seal around a tubular, a chamber defined between the upper and lower seal members; and wherein fluid enters and/or exits the chamber via some device or structure. Such a device or structure could be a relief valve, a first accumulator, a pressure control valve, an orifice, and/or a void space in a seal member in a location which contacts the tubular.

Abstract: 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.
