Patent number: 10738570Abstract: A safety valve features a flow tube operated flapper for the normal open and closed positions that can be obtained with one or two control lines to a principal operating piston. Pressure applied to the piston moves the flow tube to rotate the flapper open behind the flow tube. Release of pressure to the principal piston allows a closure spring to return the flow tube up to let the flapper close. A secondary piston can drive the flow tube with applied pressure through a control line. Cycling the applied pressure in combination with an indexing mechanism allows the flapper to be locked open and then released to normal operation. The pistons act as backup for each other as they both drive the flow tube. The flow tube has a clearance fit to the body in the locked open position to exclude debris from the flapper.Type: GrantFiled: August 14, 2019Date of Patent: August 11, 2020Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Wade A. Miller, John E. Burris

Patent number: 10294751Abstract: An operating control line is in communication with an operating piston for the safety valve as well as an equalizing piston such that pressure in the operating control line opens the safety valve and holds the equalizer valve closed. A balance chamber receives fluid from an operating piston in the safety valve when the valve opens to displace a floating piston to the open position. Operating control line pressure reduction allows valve closure and opposite floating piston movement to the closed position. If the floating piston is forced by a tubing seal leak against the open position travel stop, pressure in a balance control line against the equalizing valve member moves it from a seat to then equalize pressure on opposed ends of the floating piston allowing a bias force to move the floating piston off the open position stop so the safety valve can open despite the tubing leak.Type: GrantFiled: March 15, 2016Date of Patent: May 21, 2019Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Brett C. Jones, John E. Burris

Publication number: 20180230773Abstract: A barrier is provided in a tubular string for opening up the top of the well for drilling or completion applications. In applications where two barriers are required due to regulations a control line actuated safety valve could serve as a first barrier which a flapper is held open by a first sleeve with a seat. Another barrier (disclosed here) actuated by a first object landing on a seat to force the sleeve away from the flapper to allow the flapper to close to serve as a second barrier. After the top of the well is reclosed after being open a second object engages a seat on a second sleeve to push the flapper back to open and to lock the flapper in the open position. The objects degrade or are blown through the seats leaving the tubular passage open for the passage of tools or production flow.Type: ApplicationFiled: February 14, 2017Publication date: August 16, 2018Applicant: BAKER HUGHES INCORPORATEDInventors: Rion R.

Patent number: 9810343Abstract: The annular space surrounding a flow tube in a subsurface safety valve is sealingly isolated at opposed ends of the flow tube and pressure compensated to the tubing pressure. The subsurface safety valve is inserted and aligned in an outer housing so that hydraulic operating connections are sealingly aligned with opposite hand split ring seals that are properly compressed when the safety valve is secured in its surrounding housing. The assembly is then able to meet high pressure, heavy debris, and marine environment service requirements for subsea conditions with minimal reconfiguration for what would otherwise serve as a borehole subsurface safety valve.Type: GrantFiled: March 10, 2016Date of Patent: November 7, 2017Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Wade A.

Publication number: 20090236099Abstract: A subsurface safety valve features vertically stacked springs that are each independently supported in the valve housing and each having an opposite end that bears on a shoulder connected to the flow tube. When mounted this way their applied force is additive as they are in effect mounted in parallel between the housing and the flow tube for overcoming hydrostatic pressure in deep set applications that can exceed 20,000 feet. The stacking also allows the cross-sectional area of the flow tube to be maximized for a given housing outside diameter dictated by well conditions.Type: ApplicationFiled: March 24, 2008Publication date: September 24, 2009Inventors: John E.
