This disclosure includes flow spool riser segment assemblies that are suitable for managed pressure drilling (MPD) and that can be lowered (e.g., when connected to other riser segment assemblies) through a rotary of a drilling rig. Some embodiments are configured to have portions of the flow spool connected (e.g., without welding) below the rotary.

MPD-capable flow spools

This disclosure includes riser-component assemblies and methods of assembling the same that are suitable for managed pressure drilling (MPD) systems. For example, this disclosure includes integrated flow spool and isolation tool riser components that can be permanently coupled together and that can be configured to pass through a rotary table or other rig equipment.

Integral dsit and flow spool

This disclosure includes riser-component assemblies and methods of assembling the same that are suitable for managed pressure drilling (MPD) and that can be split apart when using pin connectors to connect auxiliary lines to other auxiliary lines and to components of the riser-component assemblies.

Splittable riser component

This disclosure includes auxiliary-line riser segment assemblies (e.g., with isolation units) that are suitable for managed pressure drilling (MPD) and that can be lowered (e.g., when connected to other riser segment assemblies) through a rotary of a drilling rig. Some embodiments are configured to have portions of the auxiliary lines connected (e.g., without welding) below the rotary.

Various connection devices and assemblies, such as telescoping riser joints, can include at least one of the present connection devices. Some of the present connection devices, for example, include a housing having a bore therethrough; a locking ring rotatably movable relative to the housing between a first position and a second position; and an engagement member laterally moveable relative to the bore of the housing between a retracted position and an extended position. In some such connection devices, the locking ring is configured such that movement from the first position to the second position causes the engagement member to move from the retracted position to the extended position.
