With respectto SAGO, as an example, a well may include a relatively horizontal portior'.i.

Such a portian may collect heated heavy oil responsive to steam injection and n ESP may be positioned horizontally to enhance flow of the heay oil [0033] In the example of Fig. i,the controller 130 can include one or more intenfaces for example, for receipt, transmission or receipt and transmission of information with the motor controller 150, a VSD unit 170, the power supply 105 (e.g., a gas fueled turbine generator, a power' oompany, etc.), the network 101, equipment in the well 103, eq uipment. in another well, etc..

[00341 As shown in Fig.. 1, the controller 130 can include or provide access to one or more modules or frameworks. Further, the controHer 130 may include features of an ESP motor controller and optionally supplant the ESP motor controller 150.

Further monitoring of power quahty from a supply to a motor at a rriotor, may occur by one or more circuits or features of a controller.

(0042] While the example of Fig. 1 shows an ESP with centrifugal pump stages, .anoher'type of ESP may be controfled. For example, an ESP may include a hydrauRo diaphragm pleotrip submersible pump HOESP), which, is a positive-displacement, double-acting diaphragm pumØ With a downhole motor. HOESPs find use in low-liquid-rate coalbed methane and other oil and gas. shallow wells that may implement artificial lift to remove water from the wellbore A HDESP can be set above or below the perforations and run in wells that are, for nample, less than about 2500 ft deep and that produce less than about 200 barrels per day. HDESPs may handle a wide variety of fluids and, for example, up th about 2% sand, coal) fines and H2S1002 As to materials of construction, materials such as, for example, those used in commercia]ly available REDATM othei submersible pumps for use n the oil and gas industry may be used.

[00431 In various examples, techniques and technologies for cables and cable coupling assemblies may help to eliminate'failure points, reduce on-site human errors, speed-up field installation, speed-up field retrieval. etc. As an example.

cable" may rerer to coiled tubing or, for example an individual cable carried by coiled tubing As an example, a cable couphng assembly may provide for couphng coded tubing and coupling one or more cabies carried by the coiled tubing For example, one end of an assembly may receive coHed tubing and another end of the assembly may provide fat coupling to one or more cables carried by the coiled tubing Such an assembly may be an end termination assembly (e g for coiled tubing)'.

[0044J As an example, a pressure balanced coiled tubing and connection assembly may include steel coil construction that supports pOwer cables and optionally other cable or line-i' as.ed services e.g., hydraulic, electrial lines, fiber optics, etc.).

(0052] In the example of Fig. 2, the coiled tubing 200 includes three main cables 210-1, 210-2 and 210-3 and three secondary cables 220-i, 220-2 and 220-3.

As shown. the main cables 210 and the secondary cabi'es 220 are supported by a bedding section 230 (e.g.. a bedding spine) about which the rnterlocking segments 240-1, 240-2 and 240-3 arc peripherally disposed (o g in a tessellated manner) An outer casing 250, which may include a weld joint260, encases the main cables 210- 1, 21 0-2 and 21 0-3, the secondary cables 220-1,220-2 and 220-3LthO bedding section 230 and. the interlocking segments.240-1, 240-2 and 240-3.

[0053] As shown ti the example of Fig. 2, the main cables 210-1, 210-2 and 210-3 may include respective layers For example, referring to the cable 210-1 may include a conductor'21'1-1, surrounded by an insulation layer 212-1 surrounded by a protection layer 214-1 (e.g, a cable jacket shield layer). As an example, a cable may include screened cable construction for additional assurance at higher voltages; For example, a cable may include one or more semi-conductor screens (consider.

eg, an inner semi-conductor screen disposed about a conductor and/or an outer semiconductor screen over insulation). As an example, the secondary cables 220, with reference to the cable 220-1, may include a core 221-1 surrounded by another layer 222-i (e.g., an insulator, a protector or shield, etc.).

[0054] As shown in the example of Fig. 2, the interlocking segments 240-1, 240-2 and 240-3, with reference to the perspective view of the interlocking segment 240, may include a groove side 242 and a rib side 244 where the groove side 242 may interlock with a rib side of another one of the interlocking segments 240 nd where, the, rib side 244 may interlock with a groove, side of another one of the interlocking segments 240. The interlocking segment 240 may incl:ude a substantially curved outer surface 248, which may be compressed within a bore formed by the outer casing 250 (e.g., as the outer casing 250 is formed about the interlocking segments 240-1, 240-2 and 2403 and components supported thereby).

As an example, the coiled tubing 200 may be fitted to an end termination assembly, for example, to form a system that can operate effectively at high external pressures In such an example, the end terrmnaton assembly may include features to a. chieve pressure balance with respect toan external environment.

[0075] As an example, an asem.bly can, include at least three cables; a bedding spine to seat the at least three cables; and interlobking segments that lock the at least three cables to the bedding spine. In such an examØle, the beddIng spine may be an extruded bedding sØine and/or each of the interlocking segments may be an extruded interlocking segment.

[0076] As an example, an interlocking segment may include a rib and a groove. As an example, an assembly may include three interlocking segments. As an example, an assembly may include an outer casing disposed about interiocking segments. As an example, such an assembiy rn ay be coiled tubing. As an example, an outer casing clan assembly rm.y be seam welded and cold drawn..

[0077] As an example, an assembly may include three power cables and at least another cable such as one or more electdcal, hydraulic and/or optical cables.

As an example, an assembly may include three power cables for a 3-phase moto.r of an electdc submersible pump.

[0076] Fig. 4 shows a cutraway view of an end termination assembly 400 as including a dry-mate connector 520 at a proximal end 420 (see., e.g.., Fig.. 5) and a cable clamp 720 in an.end cap 711 ata distal end 440 (see, e.g.., Fig. 7), which receives coiled tubing 200. The assembly 400 includes, disposed axially between the proximal end 420 and the distal end 440, a housing 620 with bellows 640 disposed in a proximal cavity 660 of the housing 620 (see, e.g.. Fig. .6), a cable boot seal 820 (see, e.g., Fig. 8), a cabJe metal seal 760 and the cable clamp 72,0 (see, e.g., r. 7).

As may be appreciated, any feature of the assembly 400 may be defined descnbed, etc with respect to the cylinddcal coordinate system, Further, spatial relationships may be specified using.

z, r and C).

(0*08&J Fig. 5 shows a perspective view of the end termination assembly 400 along with a crown plug with a wetLrnate connector 580. As indicated, the crown plug with the wet-mate connector may connect to the dry-mate connector 520 of the assembly 400 at the proximal end 420 of the assembly 400. In the example of Fig. 5, the housing 620 of the assembly 400 is shown as including a proximal end 622 and a distal end 624, The distal end 624 of the housing 620 includes an extensioh that is received via a seal compression housing 715 towbich the end cap 711 may be fit and tightened (e.g., to energize a compression seal within the seal compression housing 715) As an example, a cable termination as$embiy may include a crown plug, for example, integrally formed as a wet-mate connection system.

[0081] In the example of Fig. 5, the housing 620 receives at its proximal end 420 the drj-mate connector 520, which includes dry-mate features such as a mating surface 527, an axial face 525. a plug 521 extending from the axial face 525 where the plug 521 provides termination points for cables disposed within the housing 620.

For example, the plug 521 may include three termination points 522-1, 522-2 and 522-3 for three power cables as carried in coiled tubing (see, e.g., the coiled tubing of Fig. 2, the various coiled tubings of Fig. 3, etc.).

[0082] In the example of Fig 5, the crown plug with the wet-mate connector 580 includes a coupling member 58210 couple to the dry-mate connector 520 and internal features such as a wet niateable receptacle connector (see, e.g., US Patent No 7 112 080, which is incorporated by reference herein) 584-i for a secondary cable (see e g, the cables 220-1, 220-2 and 220-3) a three phase power wet-mate receptacle connector (see, e.g., US Patent No. US 7.731,515, which is incorporated by reference herein) 583 for one or more main cables (see e.g., the cables 210-1 210-2 and 210-3) and an end 586 with an opening lo receive one or more cables e.g., individually, in tubing, etc). The crown plug with the wet-mate connector 580 may be configured to couple to a tree such as. for example, a tree for subsea operations. As an example, the assembly 400, via the crown plug with the wet-r*nate *cqnnector.5SQ, may couple a power source to coiled tubing for a motor SUch as, for example, a motor of an ESP As an example a wet-mate crown plug may Include one or more wet-mate hydrauhc and/or fiber optic couplers for example, as well as one or more power and/or instrumentation devices.

[00831 Fig. 6 shows a cut-away view of a portion of the housing 620 of the assembiy400 wfth the dry-mate connector 520 connected via a flange 830 to the proximal end 624 at the housing $20 As shown, the housing 620 includes a bore wall 665 and an end wall 664 that form the proximal cavity 660. The bellows 640 have an annular. cylindrical form with an inner space 647 that may receive fluid via one or more fluid ports 535-1 and.535-2 disposed in the flange 530 of the dry-rrate.

connector 520, For example, the fluid ports 535-1 and 5352 (e.g., which may optionally be fitted wth filters to stop blockage via partido accumulation etc) may llow*externa1 fluid (e.g., in a completion) to enter the inner space 847 of the bellows 640 such that the bellows expands axially in the cavity 660. A..s to the inner space 647 of the bellows 640., it may bc defined by a distal end wafl 644 that caps an axially expandable cyhrdrica] inner wall 646 and an axially expandable cylindrical outer wall 64.6, which form the bellows 640.

[0084] As shown, the housing 620 may include one or more fluid ports 627-1 and 627 2 to the proximal cavity 660 for example, wtth openings at the end wall 662 of the housing 620. Fk4id may be introduced intothe cavity 660, for example, to provide for pressure balancing with respect to fluid in the inner space 647 of the bellows 640. As an example, each of the ports 627-1 and 6272 may then be seated, for example, with a pressure tight screw, an NPT plug, a welded plug, etc [0085] In the example of Fig 6, disposed interiorly to the bellows 640 are a vented cylindrical wall 633 and a diaphragm wall 637, positioied radiaHy interiorly to the vented cylindrical wall 633. As an example, the vented cylindrical wall 633 may act as a surrounding support sleeve for the diaphragm wall 637, where the vented cylindrical wall 633 may be constructed from metal and where the diaphragm wall 637 may be constructed from an elastorneric material As shown, a proximal end 632 of the vented cylindrical wall 633 and a proximal end 636 of the diaphragm wall 637 are received in a fftting 852 at or near the proximal end 622 of the housing 620 while a distal end 634 of the vented cylindrical wall 633 and a distal end 638 of the diaphragt wall 637 are received in a fitting 654 set in a shoulder 629 of the housing 620. In such an example th.e fitfing 654 may seal the distal ends. 634 and 638 of the walls 633 and 637 with respect to the th.ê housing 620.

[0086] Fig 7 shows a cut-away view of a portion of the assembly 400 that includes the cable clamp 720 and the cable metal seal 760 (see, e g Fig 4) As shown in Fig. 7, at the distal end 624 of the housing 620, .a proximal end 717 of the seal compression housing 715 fit over an extension 670 of the housing 320, for example, via a bayonet, threads or other mechanism In such an example, the seal compression housing 715 may be tightened onto the housing 620 to compress a seal component 761 One or more annular grooves 677 and 679 may provide for locating one or more seal elements, fQr example, to form one or more seals between th9 seal compression housing 71.5 and the housing 620.

(0087] As tome seal component 761, as an eample, it maybe a fePrule.with an inner surface 762 that defines an aperture for receiving and interfacing with an OUter surfa ce of the outer casing 250 of the coiled tubing 200. As an example, the seal compression housing 715 may include a distal bore neck 716 and a shoulder 718, located proximally.with respect to the distal bore neck 716. The. shoulder 718 may seat a compression fitting component 772 that indudes a conical surface 773 for fc.rrninga distal compression interface with the seal cOmponent 761. As to a proximal compression interlace, the extcnsion 70 of the housing 620 may include a conical surface 675 that extends proximally from a distal end 674 of the extension 670 of the housing 620, In such an example, as the seal compression housing 715 is torqued onto the housing 620, a compressive force is applied to the compression fitting component 772, which transmits force. to the seal component 761, which transmits force to the extension 670 of the housing 620 In such a manner, where coiled tubing 200 runs through the aperture of the seal component 761, various seal interfaces are formed Where he seal component 761 is made of metal and the oute.r casing 2.50 of the coiled tubing 200 is made of metal, a.metal-to-metal seal interface is formed. Further, where the. compression fitting component 772 is made of metal, another metal-to-metal seal interface is formed Yet further, whore the extension 670 of the housing 620 s made of metal (e g, optionally mtegral to the housing 620, which may be made of metal), yet another metal-to-metal seal interface is formed.

(0088] In the exampleof Fig. 7. the seal component 761 may include an annular groove 763 to seat a seal component As an example, the seal compression housing 715 may include a sealable port 765, Which may receive fluid to pressure test one or more seal interfaces.

O089] As to the cable clamp 720 the end cap 711 includes a distal end 714 and a poximal end 712 where the distal end 714 includes an opening to receive the coiled tubing 200 in a through bore 713 as well as openings for connection mechanism bores 7221 and 722-2 to receive bolts 7321 and 732-2 (eg., or studs, nuts and studs, etc.). As an example, the bores 722i and 722-2 may align with bores 723-1 and 723 2 in the seal compression housing 715 (e g, as part of a connection mechanism to couple the end cap 711 and the seal compression housing 715).

[0090] Within the end cap 711, a collet 741 is positioned that includes an inner surface 743, for example1 that can include integraly machined teeth or serrations so as to bite into the outer casing 250 and Thereby grip the coiled tubing 00. As shoWh, the inner sUrface 743 forms an aperture for receipt of the coiled tubing 200.

As an example, the collet 741 may be formed as a collar that can be positioned *arounctthe cofledtubing and to exert a clamping force on the cofled tubing when the bolts 32-1 and 732-2 are torqued (C g tightened) As an example, studs and nuts may be provided for applying force to the collet 741.

[0091] As an example, noting that the view of lig 7 is a cut-away view, the number of tightening mecrianisms (e g bolts, studs, etc) may be greater than two (e.g., consider three, four or more). Where the coiled tubing 200 connects to.a piece of equipment, it may support that equipmentas eH as the weight of the length of coiled tubing that extends to the piece of equipment (eg., one or more ESPs and/or other equipment) In such an example, the cable clamp 720 of the assembly 400 may be formed with sufficient integrity to support that weight (e.g.. and force of normal movements). Accordingly, the ligitening mechanisms of the end cap 711 perform two functions, to secure the end cap TI I to the seal compression housing 715 and hence the housing 620 of the assembly 400 and to secure the coiled tubing (e.g. or other tubing)to the assePibly400.

[0092] In the example of Fig 7, the coiled tubing 200 is shown as passing through the end cap 711 where it Es clamped by the coltet 741, passing through the bore neck716 of the seal compression housing 715 (e.g., an through bore of the seal compression housing 715) where Us then sealed by the seal component 761 and then passing through a bore 571 of the extension 670 of the housing 620.

As mentioned, interior to the bllows $40 is a diaphragm waIl 637, sealed at its ends and optionally supported by a support vented waIl 633 where at least the diaphragm wall 637 acts to seal the internal bore of the housing 620.

(0096] A sealed bellows cavity created by the internal diaphragm waIl 637 allows the cavity 660 to be fified with a compensation medium which may be insulation od such as a dieleotno od (e g, or gel) silicone, or mineral oil or similar nterlai. As an example, such a fiHing process may be arried out in a factory saving, for exa mple, to save time on a rig floor.

[0097] As to the cable boot seal 820 it may be used to form a sealed cap over tubing (e g, coiled tubing) As an example, the boot seal component 830 may be a cap that forms a seal, for example, such that when the assemhly 400 provides for termination of the tubing, features can aNow for a gas seal test (e g. via nitrogen, air or hefium) to be performed thereby ensuring that vartous seals are functioning correctly, for example, before filling one or more spaces (e.g., the cavity 860, the cavity 660, etc.) with dielectric gel, dielectric oil, etc. [0098] Fig. 9 shows.a series of perspective vice of en example of an end termination assembly 1400 that may terminate a coiled tubing 1200 As shown in the exrnpFe of Fig 9, the assembly 1400 includes a cable connector 1520, a housing 1620 a compression housing 1715 and an end cap 1711 where removal of the end cap 1711 reveals a collet 1741, where removal of the coVet 1741 reveals a seatihg S urface for seating the coHet 1741 (e.g., against the compression housing 1715 and/or a seal component) and where emoval of the compression housing 1715 reveals a compression fitting component*1772. In a lowermost perspective view of Fig. .9, the hcuing 1620 is shown wIth respect to a ferrule 1761 and the compression fitting component 1772 without the coiled tubing 1200, In such an example the ferrule 1761 may be compressed between the housing 1620 and the compression htting component 1772, for example by tightenrng the compression housing 1715 ono the housing 1620 (e.g.., via threads, bayonet, etc.). In Fig. 9,the end cap 1711 may include, for example, threads that engage otherthreads (e.g., or bayonet, or other mechanism.) to tighten the end cap 1711 and apply force to the collet 1741, fo example, to thereby cause the coliet 1741 to grasp and secure coiled tubing (e.g., the coiled tubing 1200).
