    Abstract: One or more remote-operated sleeve valves are placed along a tubular string downhole. The sleeves can be opened and closed wirelessly, and in embodiments over and over again. Differential pressure between wellbore fluid pressure and an accumulator chamber enable repeated shifting. Each sleeve can have a unique actuation code removing constraints regarding sequence of operation and need for well intervention to access the sleeves. Hydraulic fracturing can be achieved without wellbore obstructions, and other operations benefit for reduced expense in service rigs and the ability or selectively shut off problem zones. Remote signals received downhole include those generated by percussive and seismic, distinguishable from background noise including during pumping.

  • Patent number: 11199067
    Abstract: The present invention provides a thermally deformable annular packer with pressure relief means for use in oil and gas wells. The annular packer is formed from a stack of component parts, said parts comprising one or more eutectic alloy based ring sections sandwiched between two end sections. At least one of the annular packer component parts has one or more enclosed voids that are configured to become exposed when the packer is subjected to a predetermined pressure or temperature. The exposure of the enclosed voids serves to increase the effective volume within the sealed region formed by the annular packer in the annulus between two coaxial well casing/tubing. The increase in the effective volume serves to reduce the pressure within the sealed region thus preventing a build-up of pressure that might otherwise have damaged the well casing/tubing.

  • Patent number: 10358892
    Abstract: Salt or acid solution is stored inside a frac sleeve instead of being pumped from a surface location. A mechanically-actuated valve releases the stored salt or acid solution into the borehole to electrochemically degrade the frac ball and allow it to pass through the seat. The stored fluid can be immediately released upon mechanical actuation or released after a specified delay using an integrated timer. In multiple sleeve applications a first ball shifts a first sleeve to open treatment ports and a second ball shifts a second sleeve to close the treatment port and open screened production ports while releasing the stored material either between the seated objects or above one of the seated objects to initiate the disintegration that will allow objects on both seats to disintegrate and pass through.

  • Patent number: 10301901
    Abstract: A technique facilitates pressure containment with a retrievable cement bushing. The retrievable cement bushing includes a body and an engagement lug that cooperates with a sleeve. The engagement lug is mounted on the body and is movable to a radially outward position for engagement with a corresponding portion of a surrounding wall, e.g an internal packer wall. The sleeve is sized to receive a slick joint therethrough and is secured to a radially inward position relative to the engagement lug via a retention member movably mounted on the sleeve, so as to hold the engagement lug in the radially outward position. The sleeve protects the slick joint from inwardly directed loading via the engagement lug when the retrievable cement bushing is subjected to differential pressures.

  • Patent number: 10280709
    Abstract: An autonomous valve includes a fluid-sensitive actuator operable to automatically actuate the valve in response to being exposed to a target fluid. The target fluid may be a fluid whose presence is generally undesirable in a production fluid, such as water, and the valve may be actuated to stop flow from an interval within a wellbore that is no longer expected to produce hydrocarbon-bearing fluids. The valve further includes a protective layer disposed between the fluid inlet and the fluid-sensitive actuator, the protective layer being insoluble in the target fluid. The fluid-sensitive actuator may include a swellable piston that swells to actuate the valve in the presence of the target fluid, a soluble plug that isolates a hydraulic, closing piston until the soluble plug is dissolved into the target fluid, and an electromechanical actuator that closes the valve in response to detecting the target fluid using an electronic sensor.

  • Patent number: 10246994
    Abstract: The present disclosure relates generally to data communication in subsea oil and gas drilling and production operations. In particular, data communication from sensors located on a piece of subsea oil and gas drilling and/or production equipment to a remote location, such as to a demodulation system, is disclosed. The data communication system can include sensors for measuring various characteristics of the subsea equipment, for coding the measured data into a signal, for transmitting the signal, and for ultimately decoding the signal. The signal is transmitted along the structures which provide the containment for existing hydraulic fluid lines associated with the subsea equipment by a variety of methods, such as by pulse position modulation and/or reverse time pulse position modulation. The communication system can further include a local power generator assembly to power associated sensors and transmitters.

  • Patent number: 10081762
    Abstract: A well treatment fluid uses ingredients that include an aqueous base, a non-associative, ionic, synthetic polymer, and optionally, at least one metal crosslinker. The polymer contains a backbone and a functional group that hinders hydrolysis of the backbone. The functional group is distributed at intervals on the backbone. A well treatment method includes forming a well treatment fluid by combining ingredients including a non-associative, ionic, synthetic polymer and a first aqueous base. The first fluid exhibits a first viscosity greater than a viscosity of the first aqueous base. The method includes treating a well during a stage using the first fluid exhibiting the first viscosity. A second well treatment fluid is formed by combining ingredients including the polymer, a second aqueous base, and at least one crosslinker and by crosslinking the synthetic polymer. The method includes treating the well during another stage using the second fluid exhibiting the second viscosity.

  • Patent number: 10036229
    Abstract: A downhole tool, such as a toe sleeve, has an insert movably disposed in the housing's bore and sealably enclosing a second part of the communication path from a first port. A barrier disposed between the first and second parts of the communication path is breachable in response to a level of the applied pressure in the housing's bore. At least one retainer is engaged between the insert and the housing and at least temporarily retains the insert toward a closed position. The at least one retainer is at least partially composed of a dissolvable material and at least partially dissolves in response to the applied pressure communicated through the communication path to the second part. The at least one retainer when at least partially dissolved permits the applied pressure to initiate movement of the insert, such as from a closed position toward an opened position.
