Abstract: Downhole tools, systems, and methods for electric-based fracturing are disclosed. A downhole tool for electric-based fracturing may include an outer enclosure, an insulator chamber disposed at least partially within the enclosure, and an electrode disposed at least partially within the insulator chamber. The electrode may extend out from the insulator chamber and the enclosure, and may be configured to transfer electric energy to an exterior environment surrounding the downhole tool. The insulator chamber may be configured to thermally and electrically insulate at least a portion of the electrode from the exterior environment.

Abstract: Processes for injection of fluids into a wellbore via drill pipe. In some embodiments, the process can include positioning a downhole apparatus on a drill pipe. The process can also include placing the downhole apparatus at a desired station depth within a wellbore. The process can also include attaching a cable to the downhole apparatus from an up-hole environment. The process can also include setting at least one packer to seal a space between at least a portion of the downhole apparatus and an inner surface of the wellbore. The process can also include introducing a fluid to the downhole apparatus through the drill pipe and using a pump to inject at least a portion of the fluid into a geological stratum.

Abstract: A system comprising a tubing encased conductor (TEC), a transformer inductively coupled to the TEC, and a wireless downhole device coupled to the transformer. The wireless downhole device may include a transceiver configured to receive and/or transmit, from the transformer, a digital signal encoded in a variable current in the TEC. The digital signal may correspond to a command. In some aspects, the wireless downhole device may be powered via the transformer, a battery, or a turbine.

Abstract: In some embodiments, an apparatus may comprise a slimline connector to connect a motor lead extension (MLE) to an electric motor of an electric submersible pump (ESP) to be positioned in a wellbore, the electric motor having a rotational axis. The slimline connector may comprise multiple power ports positioned circumferentially around an axis of the slimline connector, wherein the axis of the slimline connector is parallel with the rotational axis of the electric motor, and wherein each port of the multiple power ports is associated with a different electrical phase.

Abstract: A system includes a first electrical connector configured to removably couple with a second electrical connector. The first electrical connector includes a housing having an axial opening. The first connector also includes a movable support disposed inside the housing. The movable support includes a first connector portion having a first electrical path with a first radial contact electrically coupled to a first axial contact. The first electrical connector also includes a stationary support disposed inside the housing. The stationary support includes a first mating connector portion having a first mating electrical path with a first mating axial contact coupled to a first electrical cable. The first electrical connector also includes a shuttle pin configured to engage with the second electrical connector through the axial opening in the housing. The shuttle pin is configured to move along a first axial path of travel in a first connection stage. The movable support is configured to move along a second axial path of travel in a second connection stage. The first connection stage is configured to engage the first radial contact of the first electrical connector with a first mating radial contact of the second electrical connector at a first axial position in response to the first axial path of travel. The second connection stage is configured to engage the first axial contact with the first mating axial contact over a first axial distance in response to the second axial path of travel.

Abstract: A downhole tool for connecting with a conveyance line. The downhole tool may be or comprise a connector assembly operable to connect to the line. The connector assembly may include a first connector, a second connector, a latching member, and a rotatable member. The first connector and the second connector may be configured to accommodate the line therebetween. The latching member may be latched against the first connector. The rotatable member may be operatively connected with the latching member such that rotation of the rotatable member with respect to the latching member causes relative axial movement between the latching member and the rotatable member thereby forcing the first connector and the second connector toward each other to compress the line therebetween to therefore connect the connector assembly to the line.

Abstract: A control line clamp includes a clamping element for retaining one or more control lines alongside a pipe; a first collar; and a second collar. The clamping element is arranged to be attached to the pipe by positioning the first and second collars around the pipe on opposing sides of the clamping element and moving the first and second collars relatively towards each other in an axial direction.

Abstract: There is a method for drilling a borehole in a rock formation by bombarding the borehole bottom with a laser beam, which is generated by a laser-beam generator situated outside the borehole and is guided by means of suitable auxiliary devices to a laser-drilling head situated at the borehole bottom. The drilling head is coupled with a drill rod, wherein nitrogen, supplied to the laser-drilling head via the drill rod, is split into a partial stream serving as protective gas, which protects the transmitted laser beam from interfering suspended particles. There is a further partial stream, serving as a conveying-gas stream, which transports the rock material detached from the borehole bottom out of the borehole via an annular space remaining between drill rod and borehole wall. The laser beam is guided to a laser drilling head by extending through a laser guide tube.
