Definitions
- coiled tubing In the oil and gas industries, coiled tubing (“coil”) is metal piping, usually between 1 .00 - 3.25 inches in diameter, used for well intervention and sometimes used for production tubing. Coiled tubing can be pushed into a well rather than depending only on gravity.
- the coiled tubing is a continuous length of tubular steel or composite that is flexible enough to be wound on a large reel for transportation.
- a coiled tubing unit is composed of a reel with the coiled tubing, an injector, control console, power supply, and well-control stack. The coiled tubing is injected into an existing production string, unwound from the reel and inserted into the well.
- the coiled tubing may be referred to as "coiled” even when it has been unreeled into a well.
- an electric submersible pump ESP
- ESP electric submersible pump
- ESP electrical cable may be pulled into the coiled tubing using a wire or wire rope that is pumped into the coil using "pig" attached to the wire rope.
- the downhole ends of the coiled tubing and ESP cable are terminated and the ESP is hung from the termination of the coiled tubing.
- the coiled tubing is terminated at the top of well with an ability to allow slack management of cable inside the coiled tubing, to mitigate forces on the upper connection due to the cable sliding further down into the coiled tubing over time.
- the coiled tubing is conventionally filled with fluid, such as glycol.
- An electric submersible pump (ESP) cable encapsulated in coiled tubing comprises a coiled tubing for deploying an electrical apparatus in a well, a cable in the coiled tubing in communication with the electrical apparatus, and a liquid filler occupying a space between an outside of the cable and an inside of the coiled tubing, the liquid filler curing into a supportive solid matrix.
- An example method comprises pulling a cable into a coiled tubing for deploying an electrical apparatus in a well, and pumping a liquid filler that cures into a solid matrix into the coiled tubing to secure the cable in relation to the coiled tubing.
- Another example method comprises shaping a continuous piece of flat metal around a cable for communicating power or data to an electrical apparatus in a well, seam-welding the continuous piece of metal into a coiled tubing around the cable, and pumping a liquid filler that cures into a solid filler into the coiled tubing to secure the cable in relation to the coiled tubing.

- This disclosure describes encapsulating electric submersible pump (ESP) cables that are within coiled tubing.
- An ESP cable may be either a power cable or a control cable, or both, for providing power and control to an ESP.
- coiled tubing physically suspends the ESP within a well, with ESP cable residing inside the coiled tubing.
- the coiled tubing, with the ESP cable inside is filled with a liquid, which then cures to encapsulate the ESP cable within a solid matrix inside the coiled tubing.
- the solid matrix addresses problems that occur with conventional fluid fillers, and provides a host of advantages.
- an ESP cable 100 is placed into or pulled inside of coiled tubing 102 filled with air 104, which is then pumped with a liquid filler 106 in fluid state that cures into a solid matrix 108 over time or when exposed to heat.
- the resulting solid matrix 108 may consist of a rubberized solid 108.
- the resulting solid filler 208 may consist of a closed-cell foam 208 that permanently secures the ESP cable 100 inside the coiled tubing 102. As shown in Fig.
- the example coiled-tubing deployed ESP cable described herein can use a round ESP cable 100 (e.g., tri-conductor), a flat ESP cable 302, a helically disposed ESP cable 304, a round ESP cable having only a single conductor 306, a coaxial ESP cable, or other cross-sectional shapes and types of the ESP cable 100.
- a round ESP cable 100 e.g., tri-conductor
- a flat ESP cable 302 e.g., a flat ESP cable 302
- a helically disposed ESP cable 304 e.g., a helically disposed ESP cable 304
- a round ESP cable having only a single conductor 306 e.g., a coaxial ESP cable, or other cross-sectional shapes and types of the ESP cable 100.
- a continuous strip of steel 402 or other metal that is to become the coiled tubing 402 is formed and seam-welded 404 around the ESP cable 400.
- a liquid filler 406 is pumped in, which cures into a solid matrix 408.
- This example process can be used to create a coiled tubing with encapsulated ESP cable suitable for deep wells, over 8000 feet deep.
- the continuous piece of steel 402 or other metal is seam-welded 404 around a loosely lying or helically disposed ESP cable, such as ESP cable 304 (Fig. 3) that has slack in its pre-encapsulated configuration.
- the seam- welded steel 402 becomes the coiled tubing 402.
- the coiled tubing 402 can then be pressure tested, and then pumped with the liquid filler 406 that cures into the solid matrix 408.
- the built-in slack imparts some flexibility when the coiled tubing 402 must deviate around obstacles during well insertion or intervention, or when the ESP cable 400 later tends to descend within the coiled tubing 402 by gravity under the increased weight of its long length in a deep well deployment.
- the ESP cable 100 (or 302 or 306, for example) encapsulated within the coiled tubing 102 is made corrosion resistant by adding an exterior cladding 500 of chemical-resistant alloy.
- Coiled tubing methods can be more widely implemented in general with the example implementations described below, which provide compact, solid, fully supported cable-in-tubing construction.
- the example implementations provide one or more benefits, such as 1 ) fully supported construction, 2) no cable loss management required, 3) compact end terminations, 4) continuous coiled tubing lengths beyond three kilometers, 5) integrated service lines and control lines fully supported, 6) thermal expansion of the cable can be managed using slack in the cable and additives that can be added into the fluid before solidifying, 7) total weight can be reduced by adding additives that lower the weight of the cured solid, 8) if pin holes develop on the coiled tubing in the solid-matrix-filled tube design, then fluid migration is limited, depending on the pressure differential, and 9) additives can be included in the pre-cured solid filler that swell in the presence of oil, water, salt, or gas to seal off leakage into the coiled tubing from an oil well, providing a self-healing coiled tubing deployment.
- Example implementations may use a polymeric fluid as the liquid filler 106 that cures into a solid matrix to provide a compact coiled tubing 102 with ESP cable 100 fully supported by solid filler 108 in the coiled tubing 102.
- Suitable pumpable filler materials cure in place into a deformable solid 108 that allows for some stretch and movement of the ESP cable 100 when the coiled tubing 102 passes around such items as goose necks, injectors, deviations with in the well, sheaves, spools, reels, drums, joints, casings, or as the coiled tubing 102 stretches due to its own weight or thermal expansion in offshore, deep well, or long well deployments.
- Example materials for the solid filler 108 include epoxies, silicones, ethers, esters, liquid fluorosilicones, liquid fluoroelastomers, such as a SHIN-ETSU-SIFEL potting gel (combination of a perfluoropolyether backbone with a terminal silicone crosslinking group), urethanes, or other polymers that solidify over time or when exposed to heat (Shin-Etsu Chemical Company, Ltd, Tokyo, Japan).
- SHIN-ETSU-SIFEL potting gel combination of a perfluoropolyether backbone with a terminal silicone crosslinking group
- urethanes or other polymers that solidify over time or when exposed to heat
- Additives may be included that cause the example filler material 108 to swell if exposed to specific materials, such as oil, gas, water, or salt encountered in a downhole environment.
- the swellable additive can thus respond to pinhole leaks to make a self-plugging coiled tubing 102.
- the example solid filler material 108 in its initial liquid form 106 may incorporate additives before being pumped into the coiled tubing 102 to lower density, increase buoyancy, or minimize thermal expansion.
- the lower density filler 108 can thereby reduce the overall weight of the coiled tubing-encapsulated cable.
- additives may include chopped carbon fiber, glass fiber, synthetic fiber, glass beads with air, formed particles, chopped formed particles, and so forth.
- the example solid matrix 208 may consist of a closed-cell foam 208 or 208', initially in liquid fluid state 106, exhibiting desirable properties of curability, flexibility, and chemical resistance.
- the solid foam 208 may result from gas bubbles remaining in the solid filler 208 when curing from liquid to solid.
- solid parts of the solid closed-cell foam 208' may consist mainly of the solid walls forming the closed cells of the foam 208'.
- a foam 208 may be selected to have an affinity with the metal of the coiled tubing 102 in order to create a chemical bond between the two, when needed.
- Example coiled tubing 102 for use in the example implementations may be a suitable high-strength, low-carbon steel as is often used in conventional coiled tubing.
- a layer of chemically resistant cladding such as INCONEL alloy, may be added or drawn over the coiled tubing (see Fig. 6) for enhanced chemical resistance, or the entire coiled tubing 102 may be made out of INCONEL265 or other suitable alloys (Special Metals Corporation, New Hartford, NY).
- Fig. 1 shows an example ESP cable 100 encapsulated in a rubberized solid 108 inside a coiled tubing 102.
- the example coiled-tubing-deployed ESP cable 100 is produced by pulling the ESP cable 100 into the air-filled space inside the coiled tubing 102, or attaching the ESP cable 100 to a slug or a pig that may be pumped into the coiled tubing 102 by compressed gas or other fluid.
- a curable liquid 106 is pumped in to replace the air, gas, or fluid in the coiled tubing 102.
- the curable liquid 106 sets to form a solid rubberized matrix 108 that holds the ESP cable 100 in place and prevents the ESP cable 100 from yielding when the coiled tubing 102 is bent over sheaves and drums or passed over goose necks, deviations within a well, or stretched due to its own weight in offshore or deep well deployments.
- the ESP cable 100 may have some excess length and slack intentionally built into its placement in the coiled tubing 102 when the ESP cable 100 is inserted into the coiled tubing 102.
- Fig. 2 shows an example ESP cable 100 encapsulated in a solid foam 208 inside a coiled tubing 102.
- the example coiled-tubing-deployed ESP cable 100 is produced by pulling the ESP cable 100 into the air-filled space inside the coiled tubing 102, or attaching the ESP cable 100 to a pig that may be pumped into the coiled tubing 102 by compressed gas or other fluid.
- a curable liquid 106 is pumped in to replace the air, gas, or fluid in the coiled tubing 102.
- the curable liquid 106 may consist of a polymeric fluid that sets to form the closed- cell foam 208 that holds the ESP cable 100 in place and helps to prevent the ESP cable 100 from yielding when the coiled tubing 102 is bent over sheaves, drums, over goose necks, and well curves, or stretched due to its own weight in offshore or deep well deployments.
- the ESP cable 100 may have some slack intentionally built into its placement in the coiled tubing 102 when the ESP cable 100 is inserted into the coiled tubing 102, before the curable liquid 106 sets into the solid closed-cell foam.
- the closed-cell foam filler 208 can impart more buoyancy than many solid rubberized fillers 108 and reduce the overall weight of the coiled tubing 102 with ESP cable 100 and foam filler 208 inside.
- Fig. 3 shows example ESP cables.
- the ESP cable to be used in a coiled tubing deployment may be a round ESP cable 100, such as a tri-conductor cable for three-phase power, a flat ESP cable 302, a helically coiled ESP cable 304, a single conductor power or control cable 306, a coaxial style ESP cable, or a cable of other geometrical cross- section or type.
- the ESP cable 100 may be centralized or stood-off from the inner walls of the coiled tubing 102 with periodic supports, such as periodic fins 308 or studs, that allow the pumped liquid filler 106 to pass by the supports to fill the voids in the coiled-tubing 102 until the filler 106 cures.
- periodic supports such as periodic fins 308 or studs
- An example manufacturing process for this conventional solution includes applying a thick outer jacket to a standard ESP cable, applying a continuous piece of steel to the jacketed ESP cable, forming the steel into a loose circular tube over the jacketed ESP cable through a series of shaping rollers, seam welding the loose circular tube to form the a completed steel tube, and drawing down the steel tube over the jacketed ESP cable to complete the coiled-tubing-deployed ESP cable.
- FIG. 4 shows parts of an example manufacturing process, addressing deeper wells that need coiled tubing lengths greater than approximately 8000 feet (greater than 2.4 kilometers).
- a strip of continuous steel 402 is formed lengthwise into a rounded trough around an ESP cable 400, using forms and shaping rollers. Additional series of rollers form the metal 402 into a loose circular tube 402 over the ESP cable 402.
- the ESP cable 402 can be centralized or stood-off, as described above, with fins 308, supports, or studs, etc.
- the ESP cable 400 When the loose circular tube 402 is seam-welded 404 to make coiled tubing, the ESP cable 400 is placed in a configuration that is loose with slack, to provide play for the ESP cable 400 in the finished coiled tubing 402.
- the resulting coiled tubing 402 can then be pressure tested, which is not possible in the conventional manufacture technique described above.
- the resulting coiled tubing 402 can then be filled with a curable liquid 406 that becomes the solid filler 408. If the welding of the seam-welded coiled tubing 402 is faulty, then the ESP cable 400 can be retrieved from the coiled tubing 402 without scrapping both the ESP cable 400 and the coiled tubing 402.
- Fig. 5 shows example coiled tubing 102 with chemically resistant cladding 500.
- H 2 S hydrogen sulfide
- CO 2 carbon dioxide
- Special alloy materials for the coiled tubing 102 such as INCONEL alloy, can be used as a substitute for the low-carbon steel, but this type of alloy tubing can be cost-prohibitive.
- An example implementation applies a suitable thickness of a layer of a resistant alloy 500, such as an INCONEL cladding, over example coiled tubing 102 or seam-welded coiled tubing 402 that includes a solid-filler stabilized cable, such as ESP cable 100 or ESP cable 302, for example.
- a resistant alloy 500 such as an INCONEL cladding
- coiled tubing 102 or seam-welded coiled tubing 402 that includes a solid-filler stabilized cable, such as ESP cable 100 or ESP cable 302, for example.
- a metallic coating such as a metallic bonding layer 502 may be applied first over the outer surface of the low-carbon steel coiled tubing 102 or 402 so that when the resistant cladding 500, such as INCONEL alloy is drawn down to the low carbon steel 102 or 402 the heat generated and the chemical affinity with the metallic bonding layer 502 allows the bonding of the resistant cladding 500 to the steel coiled tubing 102 or 402.
- the ESP cable 100 (or 302 or 304 or 306) inside the coiled tubing 102 or 402 may be round, flat, helical, coaxial, or of other suitable configuration.
- Fig. 6 shows an example method 600 of creating a coiled- tubing deployed ESP cable with supportive solid matrix.
- the operations are summarized in individual blocks.
- a coiled tube of appropriate size for inserting into a well is selected.
- a wire or wire rope is pumped into the coiled tube by a fluid, such as air or water.
- a fluid such as air or water.
- the air or water may move a "pig" attached to a first end of the wire rope to draw the wire rope through the coiled tube.
- An ESP cable is attached to the other end of the wire rope, and can be pulled through the coiled tubing by the wire rope.
- the fluid used to pump the ESP cable may be replaced by air.
- a liquid filler that cures into a solid matrix is pumped into the coiled tubing.
- the liquid filler may cure over time or through application of heat into a rubberized matrix or a closed-cell foam. Both ends of the coiled tubing may be capped and a slight pressure applied during the cure time to minimize shrinkage.
- the tubing may be drawn down onto the cured matrix when shrinkage or air gaps cause separation between the ESP cable elements and the inner wall of the coiled tubing.
- the ESP cable used for the above example process may be round, flat or another suitable configuration.
- the ESP conductors may be bundled into a helix to match the thermal expansion of the coiled tubing.
- centralizers or stand-offs, designed to allow through-flow can be used along the length of the ESP cable to keep the cable off the tubing inner wall, during curing time.
- Fig. 7 shows an example method 700 of creating a coiled- tubing deployed ESP cable for deep wells.
- the operations are summarized in individual blocks.
- a continuous piece of flat steel or other metal is formed through a series of shaping rollers into a length with an arc- shaped or trough-shaped cross-section.
- an ESP cable with extra slack is applied into the bottom of the arc-shaped or trough-shaped metal.
- the ESP cable and its conductors may have a round, flat, or other cross-sectional profile, or may be of helical or coaxial configuration.
- An additional series of rollers form the metal into a loose circular tube over the ESP cable.
- the cable can be centralized or stood-off, as described above.
- the adjacent edges of the metal are seam- welded to form a completed coiled tube.
- the completed tube may be pressure-tested. When a faulty seam weld is detected during the pressure testing, then the ESP cable can be retrieved from the coiled tubing without scrapping both the ESP cable and the coiled tubing.
- a liquid filler that cures into a solid matrix or forms into a closed-cell foam is pumped in to fill the space between the ESP cable and the coiled tubing.
- Fig. 8 shows an example method 800 of creating a coiled- tubing deployed ESP cable with solid filler matrix and suitable for corrosive wells. In the flow diagram, the operations are summarized in individual blocks.
- a coiled tube of appropriate size for inserting into a well is selected.
- a layer of corrosion-resistant metal or alloy is applied around the outside of the coiled tubing.
- INCONEL alloy may be applied as a cladding around the coiled tubing.

Abstract
La présente invention concerne un câble de pompe immergée électrique (« Electric Submersible Pump » ou ESP) encapsulé dans un tube spiralé. Dans un procédé illustratif, un câble d'ESP est tiré à travers le tube spiralé. Un liquide de remplissage, qui durcit pour former une matrice solide de support, est pompé dans le tube spiralé. La matrice solide peut être un matériau de remplissage caoutchouté ou une mousse à alvéoles fermées. Des additifs dans le liquide de remplissage peuvent compenser la dilatation thermique durant le fonctionnement de l'ESP, ou peuvent réduire le poids total de la matrice solide, ou peuvent gonfler en présence de pétrole, d'eau, de sel, ou de gaz pour étanchéifier des trous dans le tube spiralé. Le tube spiralé peut être formé et soudé par joints autour du câble d'ESP à partir d'une bande d'acier plate. Un long tube spiralé résistant à l'étirage pour des puits profonds peut être produit en fournissant un câble d'ESP supplémentaire pour le mou avant que le liquide de remplissage durcisse pour former une matrice solide. Le tube spiralé peut être gainé en utilisant un alliage résistant à la corrosion pour des puits corrosifs.
