Swivel Apparatus For Fixed Casing Ram
The present application pertains to a swivel insertable into a casing ram. The swivel comprises an inner mandrel having an upper end section and a lower end section configured to be operably connectable and rotatable with an upper workstring section and a lower workstring section, the inner mandrel comprising a longitudinal passage forming a continuation of a passage in the workstring. An outer housing is configured to seal the inner mandrel inside the outer housing. The outer diameter of the outer housing and the length of the outer housing is configured to fit a casing ram. In contrast to prior art tools placed within annular blowout preventers which have limited differential pressure ranges, the instant device allows for differential pressure during operation as high as 10,000 psi or more. The instant devices also may allow for aggressive frac pack treatments and facilitate reverse out operations.
Compact managed pressure drilling system attached to rotating control device and method of maintaining pressure control
A managed Pressure Drilling manifold provides accurate back pressure control of a well head when drilling. The MPD system provides two paths for the drilling fluid to flow from the RCD to the flowline. The drilling fluid flows along an MPD path sending the drilling fluids through at least one sensor, preferably three sensors, a flow control device, and a flowmeter. The MPD system also provides a bypass path that isolates the flow control device and flowmeter while direct the drilling fluid from the RCD to the bypass to avoid the flow control device and flowmeter. The MPD system provides three valves that direct the drilling fluid in the bypass path or the MPD path.
Wellhead torque ring
A wellhead assembly includes a wellhead housing; a tubing hanger, plug, back pressure valve, two-way check valve, BOP test plug, temporary abandonment plug, or other device; and a torque ring. The wellhead housing includes an inner bore. The wellhead housing has one or more mating grooves formed on an inner wall of the wellhead housing. The tubing hanger, plug, back pressure valve, two-way check valve, BOP test plug, temporary abandonment plug, or other device is positioned within the inner bore of the wellhead housing. The torque ring is positioned within a slot formed in the tubing hanger or other device. The torque ring includes a protrusion extending beyond the tubing hanger and into the mating groove.
Rotatable wear sleeve for wellhead pressure-control device
A wear sleeve for use with a rotating control device (RCD) includes a wear insert and a retainer flange. The wear insert is formed in a tube shape with an outer profile to match an inner profile of a downstream neck of the RCD to be inserted into the downstream neck. The retainer flange extending from an outer surface of the wear insert to couple with a neck flange at an end of the downstream neck of the RCD.
WELL CONTROL SYSTEM AND METHOD OF USE
The invention provides well control system for a riser. The well control system comprises a riser assembly and at least one flow meter. The at least one flow meter is configured to be mounted on the riser.
Locking clamp for a rotating control device
A clamp assembly device for connecting a rotating control device bearing assembly to a main body of a rotating control device. The device includes clamp members configured to retain the bearing assembly in place on the main body, a clamp actuator for driving clamping and unclamping of the clamp members and a lock pin controlled by a lock pin actuator. The lock pin actuator is configured to lock and unlock the clamp assembly device by moving the pin between locked and unlocked positions along an axis substantially parallel with the axis of rotation of the bearing assembly.
SEAL ELEMENTS FOR ANNULAR CONTROL DEVICES
A seal element for an annular control device includes an elastomer seal sleeve having an annular opening therein and arranged to be radially compressed to contact an exterior of a pipe disposed within the elastomer seal element. The elastomer seal sleeve comprises at least one of a wear resistant material disposed on an interior surface of the annular opening and a lubricant channel on the interior surface.
APPARATUS AND METHOD RELATING TO MANAGED PRESSURE DRILLING (MPD) WHILST USING A SUBSEA RCD SYSTEM
A subsea rotating control device (RCD) system (1; 2) adapted to permit a tubular work string to pass there through such that there is an annulus created between the inner throughbore of subsea rotating control device (RCD) system (1; 2) and the outer surface of the tubular work string.
The subsea rotating control device (RCD) system (1; 2) comprises a system housing (10) comprising a throughbore, an upper end and a lower end (10L) adapted for connection with a BOP (18) of a wellhead.
The subsea RCD system (1; 2) further comprises at least two RCD seals (302, 2302; 304, 2304) arranged for selective mounting within the system housing (10) and which are selectively actuable between an unsealed configuration and a sealed configuration.
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) 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.
Locking Clamp for a Rotating Control Device
A clamp assembly device for connecting a rotating control device bearing assembly to a main body of a rotating control device. The device includes clamp members configured to retain the bearing assembly in place on the main body, a clamp actuator for driving clamping and unclamping of the clamp members and a lock pin controlled by a lock pin actuator. The lock pin actuator is configured to lock and unlock the clamp assembly device by moving the pin between locked and unlocked positions along an axis substantially parallel with the axis of rotation of the bearing assembly.
