Patent number: 8939235Abstract: 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: February 24, 2014Date of Patent: January 27, 2015Assignee: Weatherford/Lamb, Inc.Inventors: Thomas F. Bailey, James W. Chambers, Danny W. Wagoner

Publication number: 20140367114Abstract: Latch position indicator systems remotely determine whether a latch assembly is latched or unlatched. The latch assembly may be a single latch assembly or a dual latch assembly. An oilfield device may be positioned with the latch assembly. 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.Type: ApplicationFiled: September 4, 2014Publication date: December 18, 2014Applicant: Weatherford/Lamb, Inc.Inventors: Kevin L.

Patent number: 8863858Abstract: A system compensates for heave-induced pressure fluctuations on a floating rig when a drill string or tubular is lifted off bottom and suspended on the rig, such as when tubular connections are made during NIPD, tripping, cementing operations or when a kick is circulated out during conventional drilling. In one embodiment, a pressure relief valve or adjustable choke allows the movement of fluid from the riser when the tubular moves down, and a pump with a pressure regulator moves fluid to the riser when the tubular moves up. The system also compensates for heave induced pressure fluctuations on a floating rig when a riser telescoping joint located below an RCD is moving between its retracted and extended positions while drilling.Type: GrantFiled: January 7, 2013Date of Patent: October 21, 2014Assignee: Weatherford/Lamb, Inc.Inventors: Don M. Hannegan, Thomas F. Bailey, Simon J. Harrall

Patent number: 8844652Abstract: 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: GrantFiled: September 29, 2010Date of Patent: September 30, 2014Assignee: Weatherford/Lamb, Inc.Inventors: Jonathan P.

Publication number: 20140182943Abstract: A method for drilling a wellbore includes drilling the wellbore by injecting drilling fluid into a top of a tubular string disposed in the wellbore at a first flow rate and rotating a drill bit. The tubular string includes: the drill bit disposed on a bottom thereof, tubular joints connected together, a longitudinal bore therethrough, a port through a wall thereof, and a sleeve operable between an open position where the port is exposed to the bore and a closed position where a wall of the sleeve is disposed between the port and the bore. The method further includes moving the sleeve to the open position; and injecting drilling fluid into the port at a second flow rate while adding a tubular joint(s) to the tubular string. The injection of drilling fluid into the tubular string is continuously maintained between drilling and adding the joint(s).Type: ApplicationFiled: March 4, 2014Publication date: July 3, 2014Applicant: WEATHERFORD/LAMB, INC.Inventors: David IBLINGS, Thomas F.

Publication number: 20140144706Abstract: A method for drilling a wellbore includes drilling the wellbore by advancing the tubular string longitudinally into the wellbore; stopping drilling by holding the tubular string longitudinally stationary; adding a tubular joint or stand of joints to the tubular string while injecting drilling fluid into a side port of the tubular string, rotating the tubular string, and holding the tubular string longitudinally stationary; and resuming drilling of the wellbore after adding the joint or stand.Type: ApplicationFiled: January 14, 2014Publication date: May 29, 2014Applicant: Weatherford/Lamb, Inc.Inventors: Thomas F.

Publication number: 20140138094Abstract: A Drill-To-The-Limit (DTTL) drilling method variant to Managed Pressure Drilling (MPD) applies constant surface backpressure, whether the mud is circulating (choke valve open) or not (choke valve closed). Because of the constant application of surface backpressure, the DTTL method can use lighter mud weight that still has the cutting carrying ability to keep the borehole clean. The DTTL method identifies the weakest component of the pressure containment system, such as the fracture pressure of the formation or the casing shoe leak off test (LOT). With a higher pressure rated RCD, such as 5,000 psi (34,474 kPa) dynamic or working pressure and 10,000 psi (68,948 kPa) static pressure, the limitation will generally be the fracture pressure of the formation or the LOT. In the DTTL method, since surface backpressure is constantly applied, the pore pressure limitation of the conventional drilling window can be disregarded in developing the fluid and drilling programs.Type: ApplicationFiled: January 24, 2014Publication date: May 22, 2014Applicant: Weatherford/Lamb, Inc.Inventors: Don M.

Patent number: 8701796Abstract: A rotating control device is remotely hydraulically latched and unlatched with a docking station housing for use and removal, respectively. 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 an active seal. A first sensor and a second sensor can be used to detect temperature, pressure and density of the supplied fluid at different locations and this data can be compared using a central processing unit (CPU). Also, a sensor can be used to detect the revolutions per minute of a rotating seal of the rotating control device and fluid can be provided to the rotating control device responsive to the detected revolutions per minute.Type: GrantFiled: March 15, 2013Date of Patent: April 22, 2014Assignee: Weatherford/Lamb, Inc.Inventors: Thomas F.
