Publication number: 20240125253Abstract: A valve actuation system comprises a first arm having a first arm contact surface and operatively connected to a valve actuation motion. A second arm having a second arm contact surface is operatively connected to the at least one engine valve. A discrete lost motion device is provided that is controllable between a first, motion conveying state and a second, motion absorbing state. The discrete lost motion devices comprises a plunger contact surface and a housing contact surface. The housing contact surface is configured to engage one of the first or second arm contact surfaces, and the plunger contact surface is configured to engage another of the first and the second arm contact surfaces. The first and second arm contact surfaces, the housing contact surface and the first plunger contact surface are configured to support the discrete lost motion device between the first arm and the second arm.Type: ApplicationFiled: October 10, 2023Publication date: April 18, 2024Inventors: Bruce A. SWANBON, Justin D. BALTRUCKI, Robb JANAK, G. Michael GRON, JR., John MANDELL, Marc B. SILVA, Tyler HINES, Matei ALEXANDRU, Austen P. METSACK, Gabriel S. ROBERTS, P. Douglas AUBIN, Nathaniel P.

Patent number: 9816350Abstract: A ported sub is operated with a pressure actuated shifting sleeve. A first rupture disc is set at a lower pressure than the test pressure for the tubing string that houses the ported sub. The first rupture disc breaks at a lower pressure than the string test pressure to expose well fluids to a disintegrating plug. The plug slowly disintegrates to then expose tubing pressure to a chamber and a second rupture disc with the chamber configured to have no effect on moving the sliding sleeve. When the tubing pressure is then raised to a predetermined pressure below the test pressure for the string, the second disc breaks exposing a piston to tubing pressure on one side and trapped low pressure being the opposite side of the string. The differential moves the sleeve to open a port to let tools be pumped into position without a need to perforate.Type: GrantFiled: May 5, 2014Date of Patent: November 14, 2017Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Jason C. Mailand, Christopher K. Elliott, Tyler C. Roberts

Publication number: 20150315873Abstract: A ported sub is operated with a pressure actuated shifting sleeve. A first rupture disc is set at a lower pressure than the test pressure for the tubing string that houses the ported sub. The first rupture disc breaks at a lower pressure than the string test pressure to expose well fluids to a disintegrating plug. The plug disintegrates over time to then expose tubing pressure to a chamber and a second rupture disc with the chamber configured to have no effect on moving the sliding sleeve. When the tubing pressure is then raised to a predetermined pressure below the test pressure for the string, the second disc breaks exposing a piston to tubing pressure on one side and trapped low pressure being the opposite side of the string. The differential moves the sleeve to open a port to let tools be pumped into position without a need to perforate.Type: ApplicationFiled: May 5, 2014Publication date: November 5, 2015Applicant: BAKER HUGHES INCORPORATEDInventors: Jason C.

Patent number: 8471551Abstract: A position monitoring system includes a tubular with a cavity formed therein, a magnet movable relative to the tubular, and a sensor sensible of a magnetic field of the magnet. A housing positioned within the cavity sealably isolates the sensor from environmental properties while permitting the sensor to sense the magnetic field of the magnet.Type: GrantFiled: August 26, 2010Date of Patent: June 25, 2013Assignee: Baker Hughes IncorporatedInventors: Gary B. Lake, Brock Alan Peoples, John E. Burris, David Zach Anderson, James T. Sloan, Tyler C. Roberts, Grant R. Thompson, Anthony S. Coghill, Jeremy R. Johnson

Patent number: 8439118Abstract: The problem of flappers that will not close due to high velocity gas rushing past and creating a vortex that has zones of high pressure pressing the flapper against the force of the torsion spring is reduced or overcome with modifications in the passage through a subsurface safety valve so as to reduce the intensity of the vortex to allow the torsion spring to pivot the flapper to closed position. Various shapes are inserted adjacent the flapper base to create turbulence to minimize or prevent the vortex and the associated pressure increases that would otherwise prevent flapper closure with the flow tube retracted. Inserts that create turbulence are placed in a recess that in part holds the flapper when it is rotated to the open position.Type: GrantFiled: July 28, 2010Date of Patent: May 14, 2013Assignee: Baker Hughes IncorporatedInventors: Thomas S. Myerley, Tyler C. Roberts, Grant R. Thompson

Publication number: 20120186084Abstract: A flapper base provides a flapper base body with a hinge portion unitarily formed thereupon and a flapper seat surface formed within the flowbore of the body. The flapper base may be formed from a single section of tubular metallic stock. In a method of forming a base, the stock is gripped by a rotary clamp, and a five-axis milling machine is used to cut away portions of the stock section and to form the seat surface.Type: ApplicationFiled: April 3, 2012Publication date: July 26, 2012Applicant: Baker Hughes IncorporatedInventors: Tyler C. Roberts, Barry Lee Brown, John E. Gunnells, James T. Sloan

Publication number: 20110307191Abstract: A method of determining the position of a valve includes, measuring pressure at a first location within a bore and measuring pressure at a second location within the bore wherein the first location and the second location are positioned on opposing longitudinal sides of the valve. The method further includes analyzing values from the measuring and attributing characteristics of the analyzing to specific valve positions.Type: ApplicationFiled: June 10, 2010Publication date: December 15, 2011Applicant: BAKER HUGHES INCORPORATEDInventors: Louis Lafleur, Javid Majid, Tyler C.
