A well tool pressure compensating system for connecting well tubing sections or well tools and providing pressure and/or thermal compensation along the entire length of the tool in a wellbore. The system can include first and second connectors each including fluid components and power and/or signal components. A tubing allows fluid to travel between the first and second connectors and along the tool. A hose traveling along and within the tool is in fluid communication with a wellbore fluid, thereby providing pressure and thermal compensation along the tool. A flexible tubing extends between the first and second connectors within the tool. The flexible tubing is in fluid communication with an area around the power and/or signal components of the first and second connectors, thereby providing pressure and/or thermal compensation around the power and/or signal components.

An electrical interconnect system which allows electrical service to be provided to an ESP suspended on coiled tubing without exiting the wellhead at the top of the well head structure, with three aligned plugs into which is inserted an exterior plug providing each leg of the electrical service to the ESP within the well.

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

An upper connector, a lower connector, and an inner tube, adapted to allow the passage of hydraulic control lines and/or electrical cables internally to a packer mandrel, are installed without interference with the passage of tools or flow. The conventional packer is transformed by allowing control from the surface. Hydraulic equipment (sliding sleeve valves) or transmitting/receiving data from flow rate, pressure and temperature sensors (PDGPermanent Downhole Gauge) are positioned in the production or injection string (30) below the packer. The packer includes an upper adapter, an lower adapter, and an inner tube, through which control lines or electrical cables internally pass.

The downhole rotary slip ring joint, in one aspect, includes an outer mandrel, an inner mandrel operable to rotate relative to the outer mandrel, an outer mandrel communication connection coupled to the outer mandrel, and an inner mandrel communication connection coupled to the inner mandrel. The downhole rotary slip ring joint, according to this aspect, further includes a passageway extending through the outer mandrel and the inner mandrel, the passageway configured to provide continuous coupling between the outer mandrel communication connection and the inner mandrel communication connection regardless of a rotation of the inner mandrel relative to the outer mandrel, wherein the downhole rotary slip ring joint is operable to be coupled to a wellbore access tool.

The apparatus may include a tool conveyed by a conveyance device. The tool has a body with a load bearing section, an outer surface defined by a diameter, a rotational axis, and a channel in the body extending from an opening at the outer surface. At least a part of the channel is inclined relative to the rotational axis of the body at the axial location of the opening in the body. The apparatus also includes at least one functional element disposed in the channel; and a conduit operatively connected to the at least one functional element transferring at least one of: (i) energy, (ii) a signal, (iii) a fluid, (iv) and formation material. Alternatively, the apparatus includes at least one self-contained functional element disposed in the channel.
