Abstract: A technique facilitates assembly of well equipment at a wellsite. To help lift certain types of well tools, a mounting frame may be releasably coupled to a well string, e.g. a coiled tubing string. A cable guide and a cable attachment member may be releasably coupled to a well tool which is to be moved into engagement with the well string. A cable may be routed from the cable attachment member, through the cable guide, to a cable mounting feature of the mounting frame, and to a winch. The winch is operable to draw in the cable so as to move the well tool into alignment with and up into engagement with a connector of the well string.

Abstract: Described herein are methods of recovering target ions from salt deposits. The methods include dissolving a target ion from a salt deposit to form a target solution and extracting the target ion from the target solution using a selective extraction process to yield a concentrate of the target ion which can be converted to a product.

Abstract: Apparatus and method for performing split stream operations with pressure exchangers. An example method may include operating a mixer to form a stream of concentrated dirty fluid, operating a first pump to form a pressurized stream of first clean fluid, operating a second pump to form a pressurized stream of second clean fluid, and transferring the pressurized stream of first clean fluid and the stream of concentrated dirty fluid through a plurality of pressure exchangers to pressurize the stream of concentrated dirty fluid. Thereafter, the method may further include combining the pressurized stream of concentrated dirty fluid with the pressurized stream of second clean fluid to form a pressurized stream of diluted dirty fluid, and injecting the pressurized stream of diluted dirty fluid into a wellbore during a subterranean well treatment operation.

Abstract: Apparatus and methods for reducing pressure exchanger manifold resonance. Example apparatus include a first manifold and pumps fluidly connected with the first manifold. Each pump is operable to inject a pressurized clean fluid into the first manifold. The apparatus may further include a second manifold and pressure exchangers each fluidly connected with the first and second manifolds. Each pressure exchanger is operable to receive the pressurized clean fluid from the first manifold and discharge the pressurized dirty fluid into the second manifold. The apparatus may also include a first flow restricting orifice fluidly connected along the first manifold, a second flow restricting orifice fluidly connected along the second manifold, and a discharge conduit fluidly connected with the wellbore to permit the pressurized dirty fluid to be injected into the wellbore during a well treatment operation.

Abstract: Apparatus and methods for pressurizing well operations fluids via a pressure exchanger having a housing with a bore extending between first and second ends of the housing and a rotor rotatably disposed within the bore of the housing. A chamber extends through the rotor between first and second ends of the rotor. The chamber has a larger chamber diameter section and a smaller chamber diameter section. A piston assembly is slidably disposed within the chamber. The piston assembly has a larger piston diameter section slidably disposed within the larger chamber diameter section and a smaller piston diameter section slidably disposed within the smaller chamber diameter section.

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: A system and technique for locating a tool in a channel of a blowout preventer. The system and technique may include the use of a tool locating device that includes flappers to detect tool components of a toolstring for a well application. The toolstring is segmented with deployment bars and tool components of differing diameters. For example, the deployment bars may be of a diameter that substantially matches that of an associated conveyance such as coiled tubing whereas the tool components may be of larger detectable diameters by the flappers. Once more, the flappers may also serve a centralization function as the conveyance is run through the blowout preventer.

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: 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: Methods for deploying a coiled tubing string into a wellbore include providing a coiled tubing having a distal end and an opposing end connected with a reel, providing a tool including a tool body, a valve operable under wellbore pressure disposed within the tool body, and a first fluid passageway and a second fluid passageway defined within the tool body. Fluid communication is established through the distal end of the coiled tubing and the first fluid passageway and the second fluid passageway, and the coiled tubing and tool are deployed into the wellbore.
