A stabilizer can include an outer collar, an inner sleeve, and a locking mechanism. The locking mechanism is changeable between a first mode in which the outer collar is rotationally fixed to the inner sleeve and a second mode in which the outer collar is rotationally isolated relative to the inner sleeve. The stabilizer may include an active or passive system for changing modes. An example passive device may include a magnetic clutch where the detected force overcomes magnetic forces to change mode. The stabilizer can be used to mitigate whirl on a rotating device by switching the rotating device between a rotating mode and a non-rotating mode. In the rotating mode, outer collar may rotate with the inner sleeve. In the non-rotating mode, the outer collar may be rotationally isolated from the inner sleeve.

An improved wellhead electrical connection assembly utilizing multiple sealing mechanisms to minimize pressure and fluid leakage without reliance on epoxies or other sealants. The assembly utilizes upper and lower sealing systems to provide protection at both ends of the electrical connection.

Provided is a downhole rotary slip ring joint, a well system, and a method for accessing a wellbore. The downhole rotary slip ring joint, in one aspect, includes an outer mandrel, an inner mandrel operable to rotate relative to the outer mandrel, a first outer mandrel communication connection coupled to the outer mandrel, a second outer mandrel electrical communication connection coupled to the outer mandrel, and a third outer mandrel hydraulic communication connection coupled to the outer mandrel, the first outer mandrel communication connection, second outer mandrel electrical communication connection, and third outer mandrel hydraulic communication connection angularly offset and isolated from one another, among other features

A wellhead penetrator includes a mandrel configured to be positioned in a tubing hanger, a wellhead, or both. The wellhead penetrator also includes a housing positioned at least partially within the mandrel. The housing defines a housing bore formed axially therethrough that is configured to receive upper and lower portions of a cable. The upper and lower portions are separated by a gap. The wellhead penetrator also includes a sealing element positioned at least partially within the mandrel and below the housing. The wellhead penetrator is configured to actuate from a first state to a second state in response to a downward force being exerted on the lower portion of the cable. The wellhead penetrator in the first state has the lower portion of the cable positioned at least partially within the housing such that a splice connection exists between the upper and lower portions of the cable.

An apparatus having one or more printed electrical interconnections is disclosed. The apparatus may include a chassis component of a drill string. The chassis component is configured to receive an electronic component. The apparatus also includes one or more printed electrical interconnections disposed proximate to the chassis. The one or more printed electrical interconnections are configured to communicatively connect with the electronic component.

A downhole pumping system includes a downhole pump that includes a motor and is configured to circulate a downhole fluid from a subterranean reservoir to a terranean surface; a production tubing string positioned in the wellbore from the terranean surface to the subterranean reservoir and fluidly coupled to the downhole pump; a wellbore seal positioned in the wellbore and configured to fluidly isolate a first portion of an annulus that is uphole of the downhole pump from a second portion of the annulus in which the downhole pump is positionable; and a pump power cable electrically connected to the motor and to a power source cable in the first portion of the annulus with a power connector, where each of the pump power cable and the power source cable includes a metal jacket that encapsulates the respective cable.

A wet-mate connector assembly can include a male portion having a male electrical contact with a valve metal alloy thereon. The wet-mate connector assembly can also include a female portion having a female electrical contact with the valve metal alloy thereon. The female portion can receive the male portion for defining a fluid flow path therein and can form an electrical connection with the male portion. The valve metal alloy can respond to an electrical charge and a downhole fluid by forming an insulation layer on at least one of the male electrical contact or the female electrical contact in a downhole of a well.

A deployment system as a rig less docking station with an inline male wet mate-able connectors and power cable and a motor connector with inline female wet mate-able connectors coupled to an electric submersible pump (ESP), the docking station is at the bottom of a string of production tubing and remains in the well for the life of the system while the motor connector is mated to an ESP and lowered into the well by wireline or other suitable deployment method. The rig less deployment system has a lower initial cost, larger through-bore, improved debris tolerance, and the ability for pump-assisted installation and retrieval techniques. Both the moveable female and the static male connector are pressure balanced for temperature and volume variation and the male connector utilizes a heavy dielectric fluid in a reverse labyrinth design to isolate borehole fluid from the electrical connection.

A bulkhead connector configured to be positioned within a tool body of a completion or intervention tool for use in a wellbore, and to provide a pressure and fluid seal between an area or a compartment within the tool body where one or more downhole tools are located and any fluid(s) present in the wellbore. The bulkhead connector includes one or more electrical switches positioned on the “low pressure” or tool side of the bulkhead connector, the electrical switches configured to be actuated by magnetic force(s) provided by one or more magnetic elements positioned on the “high pressure” or fluid side of the bulkhead connector. The bulkhead connector including electrical contact(s) that extend through the bulkhead connector that may be connected and disconnected from leads utilizing the magnetic force(s) provided from the fluid side of the bulkhead connector.

A system for connecting a perforating gun to at least one other component in a perforating tool string includes a perforating gun that includes a gun housing and a charge carrier received within the gun housing wherein the charge carrier includes a first electrical connector, a tool connected end-to-end with the perforating gun where the tool includes an outer sleeve and a second electrical connector, a solid signal puck arranged with the perforating gun and the tool where the puck forms a pressure resistant barrier between the gun and the tool and wherein the solid signal puck includes a first endface oriented and a second endface and an outer periphery between the endfaces, and wherein the largest outer diameter of the outer periphery is at least 40% of the length between the first endface and the second endface of the puck.
