Publication number: 20170328153Abstract: A valve stem arrangement for use in an adjustable choke, the valve stem being configured to prevent damage to components of the adjustable choke during downstream overpressure conditions. The valve stem generally connects a valve gate to an actuator for moving the valve gate within the choke. A set of shear screws couple components of the valve stem together. During overpressure conditions, the shear screws shear, permitting retraction of the valve gate towards an open position, thereby relieving loads on various choke components.Type: ApplicationFiled: December 22, 2014Publication date: November 16, 2017Applicant: Halliburton Energy Services, Inc.Inventors: Travis David Watters, Craig Godfrey, Joseph Michael Karigan

Publication number: 20170096858Abstract: A rotating control device (RCD) sensor assembly is provided. The rotating control device sensor assembly includes an emitter disposed on a rotational component of a rotating control device, wherein the emitter emanates a detectable signal field, a cap coupled to the rotational component to form a volume between the cap and the rotational component, wherein the emitter is enclosed within the volume, and wherein the cap is made of a transmissive material, and a sensor that detects the signal field through the cap as the emitter passes within a proximity of the sensor.Type: ApplicationFiled: September 8, 2015Publication date: April 6, 2017Applicant: Haliburton Energy Services, Inc.Inventors: Travis David Watters, Joseph Michael Karigan

Publication number: 20160168911Abstract: A rotating control device (RCD) can include an automatic RCD oiling system for providing lubricating oil to the RCD and preventing wellbore fluid under wellbore pressure from entering the RCD. The automatic RCD oiling system can include an oil pressure intensifier, a pump, and a pump flow controller. The oil pressure intensifier can include a piston assembly for maintaining a pressure differential between pressure from the lubricating oil on a rod side of the piston assembly and an annulus pressure corresponding to a wellbore pressure on the piston side of the piston assembly. The pump can pump lubricating oil from tank into passages to a bearing assembly of the RCD and a pump flow controller that controllably directs lubricating oil to the piston assembly and a return passage to the tank or the pump.Type: ApplicationFiled: October 25, 2013Publication date: June 16, 2016Inventor: Joseph Michael Karigan

Patent number: 8739863Abstract: An RCD can include a housing assembly containing a bearing assembly and a rotating seal which seals an annulus between a tubular string and a body of the RCD, and a remotely operable clamp device which selectively permits and prevents displacement of the housing assembly relative to the body. A method of remotely operating a clamp device can include rotating a threaded member which is secured relative to an RCD body, and displacing a clamp section in response to the threaded member rotation, thereby selectively securing and releasing a bearing assembly and an annular seal relative to the body. Another RCD can include a rotating seal which seals an annulus between a tubular string and a body of the RCD, and a remotely operable clamp device which selectively permits and prevents access to an interior of the body, the clamp device including a motor which rotates a threaded member.Type: GrantFiled: November 18, 2011Date of Patent: June 3, 2014Assignee: Halliburton Energy Services, Inc.Inventors: Leonard Charles Linde, Fredrick D.

Patent number: 6328118Abstract: Disclosed are improved apparatus and methods of separation and control of drilling fluids in under-balanced drilling. Separation is conducted at reduced pressures to improve gas separation efficiencies. Preferably, separation is performed in multiple steps of pressure drops to eliminate foaming and to enhance gas removal. Solids are removed from the shaped bottom of a separation pressure chamber by creating a slurry and fluidizing and agitating the slurry to enhance solids removal.Type: GrantFiled: March 8, 1999Date of Patent: December 11, 2001Assignee: Halliburton Energy Services, Inc.Inventors: Joseph Michael Karigan, Wesley Jay Burris, II
