Patent number: 10260327Abstract: A method for remotely controlling services to a well during hydraulic fracturing operations includes generating a high pressure fluid. The high pressure fluid is pumped into a subterranean geologic formation through a wellbore of a first well at a pressure to fracture the subterranean geologic formation. The method also includes performing a service on a second well that is located within a pressure zone defined around the first well and the second well. The method further includes controlling the performance of the service from a remote operations hub located outside of the pressure zone. The pumping into the first well may be performed simultaneously with the service on the second well.Type: GrantFiled: May 29, 2015Date of Patent: April 16, 2019Assignee: GE Oil & Gas Pressure Control LPInventors: Saurabh Kajaria, Jacob Clifton

Patent number: 10174584Abstract: An overpressure safety system for use with a distribution of pressurized fluid associated with hydrocarbon production operations includes a safety valve in fluid communication with a main bore of a fluid control manifold assembly. The safety valve has a blocking condition where the safety valve blocks a flow of pressurized fluid through the safety valve, and a venting condition where the safety valve provides a fluid flow path for the pressurized fluid at a set overpressure to pass through the safety valve. A valve member is moveable within the safety valve between a first position where a pressure side of the valve member blocks the flow of the pressurized fluid at a pressure below the set overpressure from passing through the safety valve, and a second position where the valve member provides a fluid flow path for the pressurized fluid at any pressure to pass through the safety valve.Type: GrantFiled: April 10, 2015Date of Patent: January 8, 2019Assignee: GE OIL & GAS PRESSURE CONTROL LPInventors: Saurabh Kajaria, Robert Ripple, Travis Kyle McEvoy, Keith M.

Publication number: 20180195360Abstract: A fracturing system includes a fracturing spool that mounts onto a wellhead assembly for injecting fracturing fluid into a well beneath the wellhead assembly. The fracturing system includes an isolation sleeve and fracturing spool. The isolation sleeve inserts in an axial bore of the fracturing spool, and has a lower end that extends into the wellhead to isolate and protect portions of the wellhead assembly from the fracturing fluid. A groove in an inner surface of the fracturing spool receives an annular seal for sealing between the isolation sleeve and fracturing spool.

Patent number: 9624747Abstract: A tubing hanger assembly includes a tubular outer tubing hanger member adapted to land in a bore of a wellhead. A tubular inner tubing hanger member is adapted to be secured to a string of production tubing and has an engaged position in a bore of the outer tubing hanger member. A retaining mechanism selectively allows the inner tubing hanger member to be lowered relative to the outer tubing hanger member, then selectively allowing the inner tubing hanger member to be returned back to the engaged position, to create tension in the string of production tubing. The retaining mechanism operates in response to rotational movement of the inner tubing hanger member while the outer tubing hanger member remains stationary with the wellhead.Type: GrantFiled: October 29, 2013Date of Patent: April 18, 2017Assignee: GE Oil & Gas Pressure Control LPInventors: Saurabh Kajaria, Khang V.

Patent number: 9534465Abstract: A method of completing a well includes lowering a wellhead onto a base at an upper end of the well. A hub with internal threads and an external circumferential stepped recess is secured to external threads of the wellhead. A blowout preventer assembly with an annular locking member having a plurality of locking elements is landed on the hub, and the locking elements are engaged with the recess of the hub. The well is drilled through the blowout preventer assembly to a greater depth then the blowout preventer assembly and the hub are removed. A threaded flange with a plurality of bolt holes spaced around the flange is secured to the external threads of the wellhead and a wellhead member is bolted to the bolt holes of the threaded flange.Type: GrantFiled: October 11, 2013Date of Patent: January 3, 2017Assignee: GE Oil & Gas Pressure Control LPInventors: Khang V.

Patent number: 9458688Abstract: A wellhead assembly includes a casing head, tubing head, and a production tree mounted on the tubing head. An isolation sleeve is set in a main bore of the wellhead assembly that extends across an interface between the casing and tubing heads so that a portion resides in each. The isolation sleeve is configured so that a fracturing string, and its associated hanger, can be retrieved through the isolation sleeve; which significantly reduces the time and steps required to conduct a fracturing operation in a well. Moreover, the present isolation sleeve can be used without changes to existing casing or tubing heads.Type: GrantFiled: November 20, 2013Date of Patent: October 4, 2016Assignee: GE Oil & Gas Pressure Control LPInventors: Sheila Adkinson, Saurabh Kajaria, Khang Nguyen, Knox Wright

Patent number: 9447671Abstract: A fracturing system includes a fracturing spool that mounts onto a wellhead assembly for injecting fracturing fluid into a well beneath the wellhead assembly. An isolation sleeve is included with the fracturing system that couples to the fracturing spool and extends into the wellhead to isolate and protect portions of the wellhead assembly from the fracturing fluid. A seal is between the isolation sleeve and bore of the wellhead assembly, which is threaded to the isolation sleeve. Manipulating the threaded connection between the isolation sleeve and seal selectively positions the isolation sleeve to designated axial positions within the wellhead assembly.Type: GrantFiled: July 17, 2013Date of Patent: September 20, 2016Assignee: GE OIL & GAS PRESSURE CONTROL LPInventors: Khang V.
