Abstract: An apparatus having a plurality of pressure exchangers. Each pressure exchanger includes a first conduit and a second conduit and is operable for pressurizing a low-pressure dirty fluid via a high-pressure clean fluid. Each first conduit conveys the high-pressure clean fluid into a corresponding one of the pressure exchangers and to an adjacent one of the pressure exchangers, and each second conduit conveys a pressurized dirty fluid out of a corresponding one of the pressure exchangers and from the adjacent one of the pressure exchangers. The first conduits collectively form at least a portion of a high-pressure clean fluid manifold distributing the high-pressure clean fluid among the pressure exchangers, and the second conduits collectively form at least a portion of a pressurized dirty fluid manifold combining pressurized dirty fluid collectively discharged from the pressure exchangers.

Abstract: A method moves a tube wave reflector in a well, generates a tube wave, receives a reflection, and determines the depth of one or more reflector locations from the elapsed time. Also, a method to locate a feature in a well deploys a bottom hole assembly (BHA), generates acoustic noise from the BHA, and autocorrelates to determine the BHA depth. Also, a system has a coiled tubing string to a BHA, a surface wave generator, a surface and/or distributed receiver, and a recorder to determine elapsed times between generation and receipt.

Abstract: A pressure wave system having a tubular member, a signal source, a sensor, and a source of noise, has a noise interference system employing one or more a lateral branches to cancel pressure noise, and/or amplify or filter the pressure wave signal. A related method generates the pressure wave signal, connects the lateral branch or branches to amplify or filter the signal and/or cancel noise from the system, and receives the signal or a response of the system to the signal. The lateral branches are simple pipe stubs or loops that can be made using ordinary piping components, or are more complex designs.

Abstract: A technique facilitates a fracturing operation in a borehole and surrounding formation. The technique utilizes braking to arrest the rotation of an electric frac system and to thus limit the magnitude of a pressure peak in the event of an over-pressure shut down or other type of emergency shutdown. According to an embodiment, an electric motor is coupled with a fracturing pump which may be operated to pump a fracturing fluid into a well. Stopping or otherwise braking of the electric frac system is facilitated by applying rotor drag to a rotor of the electric motor.

Abstract: Described herein are methods of recovering lithium from aqueous sources. The methods include extracting lithium from an aqueous lithium source using an extraction stage to yield a lithium intermediate; routing the lithium intermediate to a concentration stage to yield a lithium concentrate; and adjusting parameters of the ion withdrawal extraction stage to target a ratio of lithium ions to impurity ions in the lithium intermediate.

Abstract: Lithium recovery processes are described using vaporization and conversion techniques. A vaporizer can be used to concentrate lithium and precipitate impurities. A conversion process can be used to replace anions in lithium bearing streams by adding a second anion and precipitating lithium in a salt with the second anion. Rotary separation can be used to separate the precipitated lithium salt.

Abstract: Apparatus and methods for pressurizing well operations fluids via a pressure exchanger. The pressure exchanger has a housing, a rotor within the housing, a first cap covering the rotor at a first end of the housing, and a second cap covering the rotor at a second end of the housing. The rotor includes chambers distributed around a central axis of the rotor and a first fluid passage. Each of the chambers and the first fluid passage extend through the rotor between a first face of the rotor and a second face of the rotor. The first cap includes a first fluid inlet, a first fluid outlet, and a second fluid passage, and the second cap includes a second fluid inlet and a second fluid outlet. The second fluid passage fluidly connects the first fluid passage with the first fluid outlet.

Abstract: Systems and techniques for locating a tool component in a channel of a blowout preventer. The system and technique may include the use of glide rams that are configured to sealably engage a deployment bar of a toolstring supporting the tool component in the channel. The glide rams may allow for movement of the deployment bar and toolstring while maintaining the seal. Due to greater diameter of the tool component, contact with the rams may be detected in the form of a spike in load detected at an oilfield surface by equipment supporting the conveyance means for the toolstring. Thus, tool component location may be ascertained. This same diameter difference of the tool component may also be utilized to deflect a member in the channel for sake of tool location.
