A latch assembly is described for use with a rotating control device. The rotating control device provides a rotating seal to permit pressure control in an annulus surrounding a rotating tubular member such as a drill string in an offshore drilling operation. The latch assembly is operable to engage and disengage a body of the rotating control device from a remote surface location by wireless communication. An on-board actuation system is carried by the latch assembly such that no energy lines (hydraulic or otherwise) are required to couple the latch assembly to the surface location. The latch assembly may include both an operating latch mechanism and a running latch mechanism to selectively couple the latch assembly to one or both of the body of the rotating control device and a tubular member such as a drill string or other conveyance for running and pulling operations.

An integrated rotating control device and gas handling system for a marine drilling system is disclosed. The system includes a flow spool; a riser sealing tool coupled to the flow spool; a rotating control device coupled to the riser sealing tool below a tension ring of a riser section of a drilling riser, the rotating control device fluidically coupled to the flow spool; and an auxiliary line routed around the rotating control device between the riser sealing tool and the riser section.

A rotating control device (RCD), for use in drilling a wellbore, includes an RCD body, a sealing element, and a bearing assembly disposed within the RCD body and supporting an inner mandrel to rotate relative to the RCD body. The sealing element is carried by the inner mandrel, and the bearing assembly includes a bearing sealed in an internal bearing fluid chamber. The internal bearing fluid chamber includes a bearing fluid maintained at a pressure greater than a pressure of wellbore fluid in an interior of the RCD body by a pressure compensating piston between the bearing fluid contacting a first end of the piston and the wellbore fluid contacting a second, opposite end of the piston.

Pressurizing rotating control devices

In accordance with some embodiments, a drilling system comprises a drill string and a rotating control device (RCD) associated with the drill string. The RCD includes a seal element composed of an elastomeric material. A sensor is embedded in the seal element and detects a drilling condition associated with the RCD during a drilling operation. A control system determines wear of the seal element based on the drilling condition.

A method of drilling and completing a well can include drilling a section of a wellbore, positioning a perforated shroud in the section of the wellbore, securing the perforated shroud by setting a hanger, and isolating the section of the wellbore from a remainder of the wellbore vertically above the section of the wellbore. The drilling, positioning, securing and isolating steps can be performed while the section of the wellbore is not exposed to a liquid column extending to a surface location. The drilling, positioning, securing and isolating steps can be performed in a single trip of a drill string into the wellbore.
