Abstract: Apparatus and methods for pressurizing well operations fluids. An example apparatus may include a plurality of pressure exchangers each operable to receive a first fluid via a low-pressure inlet, receive a second fluid via a high-pressure inlet to thereby pressurize and then discharge the first fluid via a high-pressure outlet, and discharge the clean fluid via a low-pressure outlet. The apparatus may further include a fluid control device fluidly connected with the pressure exchangers downstream from the low-pressure outlets. The fluid control device may be a pump operable to draw the clean fluid discharged via the low-pressure outlets and thereby reduce the pressure at the low-pressure outlets and the low-pressure inlets.

Abstract: Apparatus and methods for utilizing pressure exchangers as a source of pressure oscillations. An example method includes operating a plurality of pressure exchangers to pressurize a stream of fluid, injecting the pressurized stream of fluid into a wellbore extending into a subterranean formation, and controlling rotational speed and rotational position of a rotor of each of the pressure exchangers to control amplitude and/or frequency of pressure oscillations within the pressurized stream of fluid being injected into the wellbore.

Abstract: Methods include providing a blowout preventer body having at least one sealing ram for engaging with a downhole tool, and the sealing ram is hydraulically actuatable between a ram open position and a ram closed position. A hydraulic control valve is provided and used for sensing a differential pressure across the at least one sealing ram. The hydraulic control valve is fluidly connected to the blowout preventer body, and the hydraulic control valve operates as a hydraulic interlock to prevent the at least one sealing ram from being moved to the ram open position under predetermined differential pressure conditions. The blowout pre-venter is connected to a wellhead disposed on a wellbore, and the downhole tool and coiled tubing are deployed into and out of the wellbore.

Abstract: Apparatus for deploying coiled tubing into a wellbore include a neck portion extending between end connections, where the end connections are configured to be attached to a coiled tubing tool string, and a main flow passage, at least one secondary flow passage and at least one electrical device passageway extending through the neck portion and the end connections. A wireline cable or an optical fiber is disposed in the electrical device passageway, and a well treatment fluid flows through the main flow passage. The main flow passage may have a substantially circular cross sectional shape. The apparatus includes at least one secondary flow passage having a substantially circular cross sectional shape, which may be a tube disposed within the main flow passage. The electrical device passageway may in some cases be a tube disposed within the main flow passage.

Abstract: A connector system includes a first sub and a second sub having a landing shoulder, and the first sub carries a threaded sleeve for engaging the second sub. The first sub includes a stinger section and a flying nut that provides a sealed and torque carrying connection when secured against the landing shoulder of the second sub. The first sub may be connected to the second sub without rotation of the ends of the first sub and the second sub. In some cases the first sub and the second sub are in any angular orientation when the sealed and torque carrying connection is provided. Further, the connector system may provide a connection between two sections of a downhole tool assembly without rotating or orienting in any way the angular position of the two sections. In some cases, torque applied in a wellbore milling operation further seals the sealed joint.

Abstract: A mixer sensing assembly of a mixer for mixing a wellsite fluid in a tank at a wellsite is provided. The mixer includes a shaft driven by a driver and a paddle operatively connectable to the shaft and rotatable therewith. The sensor assembly includes a mount operatively connectable to the shaft, a fluid interface, and a mixing sensor. The fluid interface is responsive to flow of the wellsite fluid passing thereby, and is connectable to the mount. The mixing sensor is connectable to the mount, the fluid interface, and/or the shaft to measure a strain applied to the thereto whereby fluid parameters of the wellsite fluid may be determined. The wellsite fluid may be mixed moving the components in the tank with the mixer, and measuring a strain on the mixer by detecting movement of the sensor assembly.

Abstract: Apparatus and methods for performing subsea drilling operations. An example method may include receiving drilling fluid from a drilling fluid source at a first pressure by a pressure exchanger located within a subsea environment and receiving seawater from the subsea environment at a second pressure by the pressure exchanger to increase pressure of the drilling fluid within the pressure exchanger to a third pressure. The second and third pressures are substantially greater than the first pressure. The method may further include discharging the drilling fluid from the pressure exchanger into piping to communicate the drilling fluid to a drill forming a wellbore in a seabed and discharging the seawater from the pressure exchanger into the subsea environment.
