Patent number: 11462849Abstract: An electrical connector having an electrical conductor member with a first opening and a second opening. Grab rings mounted in the openings have inner diameters containing teeth with crests defining a superimposed inner diameter. The teeth of the grab rings deflect and frictionally engage the outer diameter of the wires to retain them in the openings. A sleeve of insulation material covers an exterior of the conductor member. The sleeve has ends that protrude past the openings and receive an insulation layer of the wires. Resilient electrical contact members are recessed from the grab rings in the openings. The electrical contact members have inner portions biased into contact with the electrical wires and outer portions biased into contact with the conductor member.Type: GrantFiled: March 30, 2021Date of Patent: October 4, 2022Assignee: BAKER HUGHES OILFIELD OPERATIONS, LLCInventors: Sean Cain, Scott Strattan, Sarah Smith, Chad Craig

Patent number: 10683711Abstract: A string of coiled tubing for an electrical submersible well pump has insulated power conductors encased in an elastomeric jacket within the coiled tubing. A textured interface between the jacket and the inner side wall of the coiled tubing enhances frictional engagement between the jacket and the coiled tubing. The textured interface may be formed on the inner side wall of the coiled tubing and consist of a roughened or knurled surface. A tape may be wrapped helically around the jacket, the tape having an outer side with a textured surface in contact with the inner side wall of the coiled tubing. The textured interface may extend continuously for the length of the coiled tubing.Type: GrantFiled: January 16, 2018Date of Patent: June 16, 2020Assignee: Baker Hughes, a GE Company, LLCInventors: Kenneth O'Grady, John Mack, Scott Strattan, David Robert Roy

Publication number: 20070277878Abstract: Disclosed herein is a safety valve with a chemical injection configuration. The device includes a hydraulic fluid pressure operated piston at the housing. The device further includes a flow tube in operable communication with the piston and a chemical injection configuration disposed within the housing. Further disclosed herein is a method of maintaining the operation of a safety valve by injecting chemical fluid through a configuration within the safety valve. Still further disclosed herein is check valve. The check valve includes a seal, a dart having a closed head and sealable against the seal, one or more flutes on the dart, and a spring applying a biasing force to the dart to a sealing position, that force being overcomeable by a fluid pressure acting in a direction opposing the spring force.Type: ApplicationFiled: June 7, 2007Publication date: December 6, 2007Applicant: BAKER HUGHES INCORPORATEDInventors: Scott Strattan, Jeffrey Adams, Thomas Myerley, Jason Ives, Jeffrey Williams

Patent number: 7204313Abstract: A flapper valve assembly is described having an equalizing port assembly with a bleed valve member that is moveable between an open position and a closed position. The equalizing port assembly features a structural support member in the form of a retainer key that is secured to the flapper valve member both axially and radially. Additionally, a compressible spring is located between the structural support member and provides biasing force upon the valve member to urge it toward a closed position. Additionally, the flapper valve member presents a pair of raised, substantially flat actuator contact portions upon its downstream face to meet an actuating tube in a mating contact arrangement and resist material deformation that could tend to clog or block the equalizing fluid flow port.Type: GrantFiled: January 7, 2005Date of Patent: April 17, 2007Assignee: Baker Hughes IncorporatedInventors: Ronald Williams, Van McVicker, Scott Strattan, Jason B.

Publication number: 20050284547Abstract: Components of a subsurface safety valve are cast instead of machined for dramatic cost savings. In particular, the flapper is cast from a 718 nickel alloy and treated with the HIP process to increase strength and corrosion resistance while reducing porosity. Other downhole valve components are contemplated to be produced by the same technique and the materials can also be varied. Depending on the specific alloys, the resulting HIP components are either superior in performance (e.g. strength, corrosion resistance) or considerably cheaper to manufacture than their wrought counterparts.Type: ApplicationFiled: June 21, 2005Publication date: December 29, 2005Inventors: Scott Strattan, Thomas Myerly, Jeffrey Adams, William Bailey, Brian Wilfahrt

Publication number: 20050098325Abstract: Disclosed herein is a communication and lock open device which includes a lock open portion including a latch configured to engage a shifting profile on a closure member of a safety valve. Further included is a communication portion configured to rotationally align a cutter with a non-annular hydraulic bore in the safety valve and axially cut into the hydraulic bore with the cutter. Also disclosed is a method for replacing the function of a safety valve while employing an original control line including running a communication and lock open tool in a wellbore, locating the tool in a tubing retrievable safety valve and shearing a thread in the valve to render moveable a closure member of the tubing retrievable safety valve. The method includes shifting the closure member to lock the member in an open position, orienting a cutter and establishing fluid communication with a bore of the valve.Type: ApplicationFiled: October 25, 2004Publication date: May 12, 2005Inventors: Thomas Myerley, Scott Strattan
