Abstract: Polymeric electro spray emitters and related methods are generally described. In some embodiments, an emitter may be made from an ionic electro active polymer. The composition of the electro spray emitters described herein may enable the transport of ions and/or liquid ion sources, such as an ionic liquid or room temperature molten salt, through the bulk of the polymeric emitter. In some embodiments, the described emitters may be fabricated using a mixture of an ionic electroactive polymer, a solvent, and a liquid ion source to at least partially mitigate swelling effects of the polymer emitter that may otherwise occur when the one or more emitters are exposed to the liquid ion source during operation.

Abstract: Fracturing systems with frac valves for controlling flow of fracturing fluid are provided. In one embodiment, a fracturing apparatus includes a frac valve having a housing with a bore to convey fracturing fluid, a seal disposed within the bore, and an actuator coupled to control movement of the seal. The actuator can be disposed within the bore so as to move the seal between a closed position in which the seal blocks fracturing fluid flow through the bore and an open position that allows fracturing fluid flow through the bore. Additional systems, devices, and methods for fracturing are also disclosed.

Abstract: A hydrocarbon extraction system that includes an erosion control system. The erosion control system includes a housing defining a first inlet, a second inlet, and an outlet. The housing receives and directs a flow of a particulate laden fluid between the first inlet and the outlet. A conduit rests within the housing. The conduit changes a direction of the particulate laden fluid and reduces erosion of the housing. The conduit is inserted into the housing through the second inlet. The conduit defines a plurality of apertures between an exterior surface and an interior surface of the conduit. The apertures direct the fluid into a conduit cavity. The conduit guides the fluid entering the conduit cavity to the outlet. The erosion control system excludes a plug and/or a sleeve around or in the conduit.

Abstract: Fracturing systems with frac valves having gates for controlling flow of fracturing fluid are provided. In one embodiment, a fracturing apparatus includes a frac valve having a housing with a cavity transverse to a bore. A gate is positioned in the cavity and is movable between open and closed positions to selectively block flow through the bore. The gate includes a seal assembly positioned to seal against a sidewall of the cavity to surround the bore and block flow through the frac valve when the gate is in the closed position. The seal assembly can be actuated between a less-energized state and a more-energized state following movement of the gate within the cavity from the open position to the closed position. Additional systems, devices, and methods for fracturing are also disclosed.

Abstract: Fracturing systems having rams for controlling flow through fracturing trees are provided. In one embodiment, a fracturing system includes a frac stack mounted on a wellhead. The frac stack can include a flow control device having a housing and a single ram for opening and closing a bore of the housing. The single ram can form a seal with the housing around the bore without seats. Additional systems, devices, and methods for fracturing are also disclosed.
