A splicing system that accommodates the splicing of tubing having internal power cable. The splice system is amenable to use in subterranean environments where sections of continuous tubing are spliced along with the splicing of internal power cable. The splice technique comprises utilization of an expandable connector that permits lineal movement of the internal segments of power cable.

Technique for providing power to a completion used in a subterranean environment

An electric submersible pumping system having a downhole gauge section. The electric submersible pumping system comprises a submersible motor powered by a submersible pump. The submersible pump may be located below the submersible motor when in operation, while the downhole gauge section is disposed above the submersible motor. A power cable is coupled to the submersible motor through the downhole gauge section.

Technique for sensing flow related parameters when using an electric submersible pumping system to produce a desired fluid

A system for separating gas from a produced fluid. The system comprises a bottom intake completion utilized in a subterranean location. The system utilizes a gas handling system that separates a gaseous component from a fluid. The gas is vented to a separate flow path, while the fluid having a lower gas content is produced to a desired location.

A system for splicing coiled tubing used in deploying downhole equipment and having an internal power cable. The system includes first and second segments of coiled tubing each having power cable disposed therein. Additionally, mounting fixtures are attached to the ends of the coiled tubing segments that are to be joined. The system further includes a movable canister that may be slid over the spliced segments of power cable and selectively engaged with the mounting fixtures. The canister provides structural integrity to the overall deployment tubing while protecting the internal power cable splice.

A connector for use in a deployment system able to deploy and power a device, such as an electric submergible pumping system, in a well. The connector includes pluggable ends that permit connection adjacent segments, each having an outer section of tubing and an internal power cable. Each connector includes a tubing connector portion and a power cable connector portion that permit pluggable connection of sequential tubing segments when deploying a device or system downhole.

A coiled tubing system deploys an electric submergible pump system within a wellbore. The coiled tubing system includes an internal power cable for providing power to a submergible motor. Additionally, a control line, such as a hydraulic line, is disposed within the hollow interior of the coiled tubing to provide an input to the submergible pumping system. The control line is preferably routed through an interior space of a connector unit disposed between the coiled tubing and the submergible motor.

Coiled tubing system for combination with a submergible pump

A modular system for deploying and powering a device, such as an electric submergible pumping system, in a well. The modular system includes a plurality of interconnectable segments that each include an outer section of tubing and an internal power cable. Each section includes a tubing connector and a power cable connector that permits ready connection of sequential segments when deploying a device or system downhole.

Modular system for deploying subterranean well-related equipment

A technique for installing a length of cable assembly and coiled tubing includes application of both compressive and tensile forces on the cable assembly. The compressive forces are applied to the cable assembly in a compression station at an entry end of the coiled tubing. Tensile forces are applied to the cable assembly by a wire line or a similar structure situated at an exit end of the coiled tubing. Following installation of the cable assembly in the coiled tubing, the coiled tubing may be transported to an application site, and coupled to equipment, such as a submersible pumping system. The submersible pumping system may then be deployed by extension of the coiled tubing and cable assembly. Additional lengths may be obtained by joining subassemblies formed by the tensile and compressive force technique. The technique reduces residual elongation or strain in the cable assembly as compared to conventional methods.

A modular plug system facilitates engagement and disengagement of the power cable with a submergible pumping system. The modular plug includes a first plug portion connected to the power cable and mounted within an upper assembly of the connector. The plug also includes a second plug portion connected by a plurality of conductors with the submergible motor. The second plug portion is mounted within a lower assembly of the connector and is configured for mating engagement with the first plug portion. The upper assembly and lower assembly of the connector also are designed for relatively easy engagement and disengagement coincident with the engagement and disengagement of the plug.

A technique is provided for retaining a cable assembly in a length of conduit, such as coiled tubing. The retaining assembly is secured to an end of the coiled tubing and to tensile members of the cable assembly. A retainer element may be secured directly to conductors of the cable assembly for holding the cable assembly adjacent to the retaining structure. The retainer may include a flat plate-like structure which abuts against a surface of the assembly, such as against an upper surface of a connector to prevent re-entry of the cable into the coiled tubing. Following attachment of the cable and coiled tubing, the submersible equipment coupled to the coiled tubing may be retracted or withdrawn from the well. Certain of the conductors may be coupled to monitoring circuitry for continuously monitoring well parameters during such repositioning. The technique may be used during initial installation of coiled tubing deployed systems, or during subsequent removal or servicing of the equipment.

A suspension structure is disclosed for use in running well hardware such as a pumping assembly by cable into a well and pulling the hardware from the well, the structure including two suspension masts. One of the masts is a lightweight mast having a working height sufficient to suspend the hardware above a well platform or the like on which the masts are mounted but not having a load capacity sufficient to withstand the forces required to pull the hardware from the well. The other mast is a short mast of high-load capacity capable of withstanding such forces but not of sufficient height to suspend the hardware. The two masts are used alternatively for running and pulling operations.
