Abstract: A system and method for hydraulic isolation of a downhole powered system. The system and method include a sliding sleeve, venting assemblies with venting ports, and check valves associated with a vent body, and an isolation sleeve, isolation valve, and integral packer for controlling fluid flow through the motor and pump assembly of the powered system. Also disclosed is a wet connect mandrel modified to receive the isolation sleeve, the isolation sleeve preferably capable of permitting the passage of tools therethrough and capable of preventing fluid through the inlet of the mandrel. The mandrel may also be outfitted with a built-in sliding sleeve. The sleeves, valves and packer can be actuated mechanically, hydraulically or electrically. Electrical actuation can be facilitated using the power from an adjacent wet connect mandrel.

Abstract: Disclosed are methods and devices for testing downhole connector electrical systems and cable integrity during installation of a permanent completion, including a customized retrievable plug arm assembly connectable to the completion during RIH, the tool mimicking a retrievable ESP, but without motor, and can be employed with or without pressure isolation. Another method employs a slidable starpoint located within the downhole wet mate connector of the completion to provide continuous electrical contact between the phases when no retrievable assembly is in place. When a retrievable assembly is later put in place, the slidable starpoint is moved into a second position that no longer provides electrical contact between the phases. Another method uses fusible links installed between two conductors within the downhole electrical connector system of the completion to provide similar electrical contact between phases, the fusible link configured to melt away once motor current is sent through the conductors.

Abstract: Disclosed are methods and systems comprised of devices for enabling two-way communication between downhole tools and surface equipment through standard slickline and braided line cable and using such data to perform a variety of actions. The disclosed methods include surface and downhole communication modules, both of which contain a means to generate pulses, a means to detect pulses traveling through the cable, and onboard electronics; a surface control system acts as the principal input/output device and interface to a user, as data is displayed on such systems and its input device allows for this operator to send instructions to a plurality of downhole tools. Sensors, detectors, power sources, and actuators are all controlled by onboard electronics; and one or more processors operably connected to these devices. A processor is typically configured to receive data from the modules, record the data, and transmit data to allow for an operator to perform actions based on the data.

Abstract: A permanent completion system is disclosed comprising: an upper ACP installed in the wellbore powered by a first power cable from the surface; a lower ACP installed in the wellbore below the upper ACP, and being powered by a second power cable from the surface and being connected to the upper APC by a spacer tube; and a heating assembly connected to the lower ACP in the wellbore and receiving power from the second power cable, the heating assembly, such as a mineral insulated heater cable, providing heat to the wellbore. The heating assembly preferably is retrievable and can be conveyed to the lower ACP by coil tubing. The coil tubing can be removed after conveying the heating assembly into place to permit further access to the upper ACP, e.g., to permit mechanical and electrical connection of a retrievable ESP assembly to the upper ACP.

Abstract: A stress cone for reducing electrical stresses is disclosed for use on terminated ends of tubing encapsulated power cable used in surface applications in a subsurface well power system employing electric submersible pumps (ESPs). The stress cone comprises an annular section about a longitudinal axis for receiving a terminated end of the TEPC in its first end and for abutting the terminated metal TEPC end against a metal shoulder at its second end therein, and an insulation chamber axially aligned with and connected to the annular section. The chamber comprises a metal interior surface symmetrical about the axis. The insulated TEPC core (without outer metal sheath) passes through the insulation chamber along the axis and then exits. The ID of the TEPC metal sheath and the inside metal surface of the chamber form a smooth ground plane transition surface. Insulation material surrounds the TEPC insulation layer within the insulation chamber.

Abstract: A wellbore insert comprises a housing that further comprises an inner annulus and one or more ports dimensioned and configured to provide a fluid pathway between the inner annulus of the housing and the outer surface of the housing. A selectively movable port seal, operable via a port seal mover, is dimensioned and configured to selectively occlude or open these ports. A movable plug, controlled by a plug mover, operates within the housing to selectively permit or occlude fluid flow within the housing. A power supply and a detector are typically present within the housing. An individually addressable electronic control module is operable to effect a change in the position of the selectively movable port seal and/or the movable plug. The wellbore insert can be used for downhole operations such as frac operations.
