Description

WEIGHTED SPOOLABLE PIPE
RELATED APPLICATIONS
[0001] This application claims priority to application U.S.S.N. 60/890,080 filed February 15, 2007, hereby incorporated by reference in its entirety.

BACKGROUND
[0002] Steel pipe is commonly used in the oil and gas industry. This type of pipe may be used in the transport of fluids to or from the well such as oil and gas gathering lines, flow lines, and fluid and gas injection lines which may be installed on the surface or buried. Steel pipe may also be used for downhole applications such as drilling, intervention, or production including drill strings, coiled tubing, production tubing, casing, and velocity and heater strings, and the like. Steel pipelines, gathering lines or injection lines are usually installed using short (30-40 foot) sections. This requires additional labor and provides the possibility for fluid leakage at each fitting. Such labor intensive installation may also lead to lost revenues if production or transport of the fluids is suspended during the installation.
[0003] To resist internal corrosion, steel alloys, non-metallic internal coatings, or fiberglass-reinforced epoxy pipe may be used, but all may still have the disadvantage of being sectional products. In addition, the wall of a fiberglass-reinforced epoxy pipe may be fairly damage intolerant and may requires careful handling, installation, and/or use of specific back-fill materials. Damage or cracks in the fiberglass reinforced epoxy layer can in some cases lead to small leaks or "weeping" of the pipe under pressure. In some applications, thermoplastic liners may be used as corrosion protection inside steel pipe, but these liners are susceptible to collapse by permeating gases trapped in the annulus between the liner and the steel pipe if the pressure of the bore is rapidly decreased. Unreinforced thermoplastic pipe, on the other hand, can usually only tolerate relatively low pressures especially at temperature and in the presence of oilfield fluids.
[0004] Fiberglass reinforced epoxy tubes used in oil and gas applications may have positive buoyancy, and thus may float, move, or otherwise have instability when in muddy, sandy or flooded ground unless weighted down. While in some situations positive buoyancy may be desirable, positive buoyancy can affect the performance of the tube and can also lead to an increase in damage from movement of the pipe in ground. Problems associated with positive buoyancy may be particularly acute with tubes that are manufactured from low-density structural materials or have large volumes of bore relative to the volume and density of the structural material.
[0005] Therefore, there is a need for a weighted, low-cost, corrosion resistant, spoolable, reinforced inner-lined pipe for such relatively low pressure applications so that the tube remains negatively buoyant when in use.

SUMMARY
[0006] Disclosed is a reinforcing material that includes fibers and a solid hydrocarbon matrix. Such a reinforcing material may be used as a reinforcing layer, for example, in a spoolable pipe that may also include an inner layer and an outer layer. Also disclosed is a spoolable pipe comprising at solid hydrocarbon matrix or wax.

DETAILED DESCRIPTION

[0010] To provide an overall understanding, certain illustrative embodiments will now be described; however, it will be understood by one of ordinary skill in the art that the systems and methods described herein can be adapted and modified to provide systems and methods for other suitable applications and that other additions and modifications can be made without departing from the scope of the systems and methods described herein.
[0011] Unless otherwise specified, the illustrated embodiments can be understood as providing exemplary features of varying detail of certain embodiments, and therefore, unless otherwise specified, features, components, modules, and/or aspects of the illustrations can be otherwise combined, separated, interchanged, and/or rearranged without departing from the disclosed systems or methods. Additionally, the shapes and sizes of components are also exemplary and unless otherwise specified, can be altered without affecting the scope of the disclosed and exemplary systems or methods of the present disclosure.

[0012] Disclosed herein is a spoolable tube that provides a path for conducting fluids (i.e., liquids and gases) along the length of the spoolable tube. For example, the spoolable tube can transmit fluids down a well hole for operations upon the interior surfaces of the well hole, the spoolable tube can transmit fluids or gases to hydraulic or pneumatic machines operably coupled to the spoolable tube, and/or the spoolable tube can be used to transmit fluids, underwater, underground, or on surface systems from well holes or other equipment to transmission, distribution pipelines or other equipment. Accordingly, the spoolable tube disclosed herein can provide a conduit for powering and controlling hydraulic and/or pneumatic machines, and/or act as a conduit for fluids, for example gases or liquids. In some embodiments, the spoolable tubes disclosed herein are used for relatively low pressure applications, where the pressure of a fluid being transported by a disclosed tube is about 1 to about 1000 psi, or about 10 to about 500 psi.
[0013] The articles "a" and "an" are used herein to refer to one or to more than one (i.e. to at least one) of the grammatical object of the article. By way of example, "an element" means one element or more than one element.
[0014] Figure 1 illustrates a cross-section of a circular spoolable tube 10 constructed of an internal pressure barrier 12, a reinforcing layer 14, a weight layer 16, and an external layer 56.
The spoolable tube can be generally formed along a longitudinal axis 17.
Although illustrated in Figure 1 as having a circular cross-section, the disclosed spoolable tube can have a variety of tubular cross-sectional shapes, including but not limited to circular, oval, rectangular, square, polygonal, and/or others.
[0015] The internal pressure barrier 12, otherwise referred to as a liner, can serve as a pressure containment member to resist leakage of internal fluids from within the spoolable tube 10. In some embodiments, the internal pressure barrier 12 can include a polymer, a thermoset plastic, a thermoplastic, an elastomer, a rubber, a co-polymer, and/or a composite. The composite can include a filled polymer and a nano-composite, a polymer/metallic composite, and/or a metal (e.g., steel, copper, and/or stainless steel). Accordingly, an internal pressure barrier 12 can include one or more of a polyethylene, a cross-linked polyethylene, a polyvinylidene fluoride, a polyamide, polyethylene terphthalate, polyphenylene sulfide and/or a polypropylene, or combinations of these materials, either as distinct layers or as blends, alloys, copolymers, block copolymers or the like. The internal pressure barrier may also contain solid state additives. In one embodiment, the internal pressure barrier 12 includes a modulus of elasticity greater than about approximately 50,000 psi, and/or a strength greater than about approximately 1,000 psi. In some embodiments, the internal pressure barrier 12 can carry at least fifteen percent of the axial load along the longitudinal axis, at least twenty-five percent of the axial load along the longitudinal axis, or at least thirty percent of the axial load along the longitudinal axis at a termination, while in some embodiments, the internal pressure barrier 12 can carry at least fifty percent of the axial load along the longitudinal axis at a termination.
Axial load may be determined at the ends of a tube. For example, at the ends, or a termination, of a tube, there may be a tensile (e.g. axial) load equal to the internal pressure multiplied by the cross-sectional area of the inner diameter of the pipe.
[0016] Referring back to Figure 1, the spoolable tube 10 can also include one or more reinforcing layers 14. In one embodiment, the reinforcing layers can include fibers having at least a partially helical orientation relative to the longitudinal axis of the spoolable tube. The fibers may have a helical orientation between substantially about thirty degrees and substantially about seventy degrees relative to the longitudinal axis 17. For example, the fibers may be counterwound with a helical orientation of about 40 , 45 , 50 , 55 , and/or 60 . The reinforcing layer may include fibers having multiple, different orientations about the longitudinal axis. Accordingly, the fibers may increase the load carrying strength of the reinforcing layer(s) 14 and thus the overall load carrying strength of the spoolable tube 10. In another embodiment, the reinforcing layer may carry substantially no axial load carrying strength along the longitudinal axis at a termination.
[0017] The reinforcing layer(s) 14 can be formed of a number of plies of fibers, each ply including fibers. In one embodiment, the reinforcing layer(s) 14 can include two plies, which can optionally be counterwound unidirectional plies. The reinforcing layer(s) can include two plies, which can optionally be wound in about equal but opposite helical directions. The reinforcing layer(s) 14 can include three, four, five, six, seven, eight, or more plies of fibers, each ply independently wound in a helical orientation relative to the longitudinal axis. Plies may have a different helical orientation with respect to another ply, or may have the same helical orientation. The reinforcing layer(s) 14 may include plies and/or fibers that have a partially and/or a substantially axial orientation. The reinforcing layer may include plies of fibers with a tape or coating, such as a tape or coating that includes abrasion resistant material or polymer, disposed between each ply, underneath the plies, on the outside of the plies, or optionally disposed between only certain plies. In some embodiments, an abrasion resistant layer is disposed between plies that have a different helical orientation.
[0018] The fibers can include structural fibers and/or flexible yarn components. The structural fibers can be formed of graphite, glass, carbon, KEVLAR, aramid, fiberglass, boron, polyester fibers, polyamide, ceramic, inorganic or organic polymer fibers, mineral based fibers such as basalt fibers, metal fibers, and wire. The flexible yarn components, or braiding fibers, graphite, glass, carbon, KEVLAR, aramid, fiberglass, boron, polyester fibers, polyamide, ceramic, inorganic or organic polymer fibers, mineral based fibers such as basalt fibers, metal fibers, and wire. For example, structural and/or flexible fibers can include glass fibers that comprise e-glass, c-cr glass, Advantex , s-glass, d-glass, borosilicate glass, soda-lime glass or a corrosion resistant glass. The fibers included in the reinforcing layer(s) 14 can be woven, braided, knitted, stitched, circumferentially wound, helically wound, axially oriented, and/or other textile form to provide an orientation as provided herein (e.g., in the exemplary embodiment, with an orientation between substantially about thirty degrees and substantially about seventy degrees relative to the longitudinal axis 17). The fibers can be biaxially or triaxially braided.
[0019] Reinforcing layers contemplated herein may include fibers that are at least partially coated by a matrix, or may include fibers that are embedded within a matrix, or may include a combination. A reinforcing layer may comprise up to about 30% of matrix by volume, up to about 50% of matrix by volume, up to about 70% of matrix by volume, or even up to about 80%
or higher by volume.

[0020] The matrix material may be a high elongation, high strength, impact resistant polymeric material such as epoxy. Other alternative matrixes include nylon-6, vinyl ester, polyester, polyetherketone, polyphenylen sulfide, polyethylene, polypropylene, thermoplastic urethanes, and hydrocarbons such as waxes or oils. For example, a reinforcing layer may also include a matrix material such as polyethylene, e.g. low density polyethylene, medium density polyethylene, linear low density polyethylene, high density polyethylene, polypropylene, cross-linked polyethylene, polybutylene, polybutadiene, or polyvinylchloride.
[0021] A reinforcing layer may further include pigments, plasticizers, flame retardants, water resistant materials, water absorbing materials, hydrocarbon resistant materials, hydrocarbon absorbent materials, permeation resistant materials, permeation facilitating materials, lubricants, fillers, compatibilizing agents, coupling agents such as silane coupling agents, surface modifiers, conductive materials, thermal insulators or other additives, or a combination of these.
[0022] In one embodiment, the reinforcing layer(s) 14 includes fibers having a modulus of elasticity of greater than about 5,000,000 psi, and/or a strength greater than about 100,000 psi.
In some embodiments, an adhesive can be used to bond the reinforcing layer(s) 14 to internal pressure barrier 12. In other embodiments, one or more reinforcing layers are substantially not bonded to one or more of other layers, such as the inner liner, internal pressure barriers, or external layer(s).
[0023] Weight layer 46 may provide spoolable tube 10 with weight so that the pipe may become negatively buoyant. Weight layer 46 may comprise fibers wound over reinforcing layer 14. In one embodiment, a weight layer 46 can include fibers having at least a partially helical orientation relative to the longitudinal axis of the spoolable tube. Fibers for use in such a weighted layer may include glass, graphite, carbon, KEVLAR, aramid, fiberglass, boron, polyester fibers, polyamide, ceramic, inorganic or organic polymer fibers, mineral based fibers such as basalt fibers, metal fibers, and wire. Fibers for use in a weighted layer may include those fibers with a specific density greater than or about 2 g/cm3.
[0024] Fibers for use in a weight layer 46 may be impregnated or coated with a fiber protecting substance to, e.g. prevent water from interacting with the fiber.
Fibers present in weight layer 46 may also include materials that displace air that may be present in a weighted layer that includes fibers. For example, dry glass fibers used in such a weighted layer may have entrapped air that contribute to 40% of the volume of such a layer. Air displacing materials may include fiber coatings, polymers, water, and hydrocarbons such as oil or grease.
[0025] In some embodiments, one or more weight layers may be substantially free of the reinforcing layer, e.g. substantially free of a matrix which comprises at least part of a reinforcing layer. Alternatively, a weight layer may consist essentially of fibers.
[0026] Weight layer(s) 46 may also include a tape disposed over the fibers to, for example, to hold the weight layer fibers together, which may be useful e.g. during processing. Such a tape may be permeable to water or have perforations so that water may saturate the weighted layer.
For example, a water saturated weight layer may have more weight than a dry layer.
[0027] The external layer(s) 56 can provide wear resistance, UV, and impact resistance or thermal insulation, or selectively increase or decrease the permeability. .
For example, the external layer 56 can provide abrasion resistance and wear resistance by forming an outer surface to the spoolable tube that has a low coefficient of friction thereby reducing the wear on the reinforcing layers from external abrasion. Further, the external layer 56 can provide a seamless layer, to, for example, hold the inner layers 12, 14 of the coiled spoolable tube 10 together.
Alternatively, external layer 56 may be permeable to fluids such as gasses arising from fluids transported in the spoolable tube 10, for example, external layer can include a plurality of perforations. Such permeablity may facilitate the removal or escape of such gasses and thus prevent, e.g. bursting of the tube. Such permeability of external layer 56 may, in some embodiments, facilitate the incorporation of water in the weight layer 46.
[0028] The external layer 56 can be formed of a filled or unfilled polymeric layer.
Alternatively, the external layer 56 can be formed of a fiber, such as aramid or glass, with or without a matrix. Accordingly, the external layer 56 can be a polymer, thermoset plastic, a thermoplastic, an elastomer, a rubber, a co-polymer, and/or a composite, where the composite includes a filled polymer and a nano-composite, a polymer/metallic composite, and/or a metal.
In some embodiments, the external layer(s) 56 can include one or more of polyethylene, a cross-linked polyethylene, a polyvinylidene fluoride, a polyamide, polyethylene terphthalate, polyphenylene sulfide and/or a polypropylene. The external layer 56 can include a modulus of elasticity greater than about approximately 50,000 psi, and/or a strength greater than about approximately 1,000 psi. In an embodiment, the external layer 56 can carry at least ten percent, twenty percent, twenty-five percent , thirty percent or even at least fifty percent of an axial load in the longitudinal direction at a termination. A seamless external layer can comprise, for example, a perforated thermoplastic.
[0029] In some embodiments, the external layer 56 can be formed by extruding, while the layer 56 can be formed using one or more materials applied at least partially helically and/or at least partially axially along the longitudinal axis 17. The material can include, for example, one or more polymeric tapes. In an example embodiment, the external layer 56 can include and/or otherwise have a coefficient of friction less than a coefficient of friction of a reinforcing layer 14.
[0030] Particles can be added to the external layer 56 to increase the wear resistance of the external layer 56. The particles used can include one or more of ceramics, minerals, metallics, polymerics, silicas, or fluorinated polymers. For example, adding TEFLON (MP
1300) particles and an aramid powder (PD-T polymer) to the external layer 56 can reduce friction and enhance wear resistance. Particles, for example, Ti02 or carbon black, may be added to increase UV
resistance of the external layer.

[0031] It can be understood that pressure from fluids transported by the spoolable tubes 10 disclosed herein may not be properly released from the reinforcing layer(s) 14, and/or from the inner pressure barrier liner and/or from within the external layer, without, for example, an external layer having a sufficient permeability to provide such pressure release. Such accumulation of pressure can cause deterioration of the spoolable pipe 10, for example, external layer rupture or inner pressure barrier collapse when bore pressure is reduced. Accordingly, in some embodiments, to allow for pressure release along the length of the spoolable pipe 10, the external layer(s) 56 can include and/or have a permeability at least five, or at least ten times greater than the permeability of the internal pressure barrier 12, or the reinforcing layer 14. For example, external layer(s) 56 include perforations or holes spaced along the length of tube. Such perforations can, for example, be spaced apart about every 10 ft, about every 20 ft, about every 30 ft, and even about or greater than about every 40ft. In one embodiment, the external layer 56 can be perforated to achieve a desired permeability, while additionally and optionally, an external layer 56 can include one or more polymeric tapes, and/or may be discontinuous.
[0032] Figure 2 illustrates a spoolable tube 10 elongated along an axis 17 and having an internal pressure barrier 12, a reinforcing layer 14, and at least one weight layer 46 enclosing at least partially the reinforcing layer(s) 14. Such a tube may also include an external layer(s) 56 (not shown) that may otherwise be understood to be an outer protective layer.
In some embodiments, the external layer 56 is substantially unbonded to one or more of the reinforcing layer(s) 14, and/or substantially unbonded to the weight layer 46, or substantially unbonded to one or more plies of the weight layer(s) 46. The external layer 56 may be partially bonded to one or more other layers of the tube.

[0033] The disclosed spoolable tubes 10 can also include one or more couplings or fittings.
For example, such couplings may engage with, be attached to, or in contact with one or more of the internal and external layers of a tube, and may act as a mechanical load transfer device.
Couplings may engage one or both of the inner liner, the external wear layer or the reinforcing layer. Couplings or fittings may be comprised, for example, of metal or a polymer, or both with or without elastomeric seals such as 0-rings. In some embodiments, such couplings may allow tubes to be coupled with other metal components. In addition, or alternatively, such couplings or fittings may provide a pressure seal or venting mechanism within or external to the tube. One or more couplings may each independently be in fluid communication with the inner layer and/or in fluid communication with one or more reinforcing layers and/or weight layer, and/or in fluid communication with an external layer. Such couplings may provide venting, to the atmosphere, of any gasses or fluids that may be present in any of the layers between the external layer and the inner layer, inclusive.
[0034] With reference to Figure 3, the disclosed spoolable tubes 10 can also include one or more energy conductors 62 that can be integral with the wall of the spoolable pipe. Accordingly, the energy conductors 62 can be integral with the internal pressure barrier, reinforcing layer(s), and/or exist between such internal pressure barrier 12 and reinforcing layer 14, and/or exist between the internal pressure barrier 12 and the weight layer 46, and/or exist between the reinforcing layer 14 and an external layer. In some embodiments, the energy conductor 62 can extend along the length of the spoolable tube 10. The energy conductors 62 can include an electrical guiding medium (e.g., electrical wiring), an optical and/or light guiding medium (e.g., fiber optic cable), a hydraulic power medium (e.g., a high pressure tube or a hydraulic hose), a data conductor, and/or a pneumatic medium (e.g., high pressure tubing or hose).
[0035] The disclosed energy conductors 62 can be oriented in at least a partially helical direction relative to a longitudinal 17 axis of the spoolable tube 10, and/or in an axial direction relative to the longitudinal axis 17 of the spoolable tube 10.
[0036] A hydraulic control line embodiment of the energy conductor 62 can be either formed of a metal, composite, and/or a polymeric material.
[0037] In one embodiment, several energy conductors 62 can power a machine operably coupled to the coiled spoolable tube 10. For instance, a spoolable tube 10 can include three electrical energy conductors that provide a primary line 62, a secondary line 62, and a tertiary line 62 for electrically powering a machine using a three-phase power system.
As provided previously herein, the spoolable tube 10 can also include internal pressure barriers 12 for transmitting fluids along the length of the tube 10.
[0038] Although the methods, systems and tubes have been described relative to a specific embodiment(s) thereof, they are not so limited. Obviously many modifications and variations may become apparent in light of the above teachings. Many additional changes in the details, materials, and arrangement of parts, herein described and illustrated, can be made by those skilled in the art. Accordingly, it will be understood that the following claims are not to be limited to the embodiments disclosed herein, can include practices otherwise than specifically described, and are to be interpreted as broadly as allowed under the law.
