Title: Coiled tubing servicing tool

Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This application is a divisional of application Ser. No. 13/771,628, filed 20 Feb. 2013, which is hereby incorporated by reference in its entirety for all purposes. 
    
    
     BACKGROUND 
     Coiled tubing may be used in a variety of wellbore servicing operations including drilling operations, completion operations, stimulation operations, and other operations. Coiled tubing refers to relatively flexible, continuous tubing that can be run into the wellbore from a large spool which may be mounted on a truck or other support structure. While a rig must stop periodically to make up or break down connections when running drilling pipe or other jointed tubular strings into or out of the wellbore, coiled tubing can be run in for substantial lengths before stopping to join in another strand of coiled tubing, thereby saving considerable time by comparison to jointed pipe. The coiled tubing is typically run into and pulled out of the wellbore using a device referred to as an injector. As the injector feeds coiled tubing into the wellbore, coiled tubing is unrolled or “paid out” from the coiled tubing spool. As the injector withdraws coiled tubing out of the wellbore, coiled tubing is rolled onto or taken up by the coiled tubing spool. 
     Conventionally, sensors and/or other equipment may be incorporated within the coiled tubing to communicate temperature, pressure, and/or other data to the surface via data conduits such as electrical wires and/or optical fibers. The data conduits may interface with the operation of surface equipment which collect and store data measurements for various parameters (e.g., pressure, temperature) of the wellbore. For proper operation and reliable data measurements, the sensors need to be accurately and/or safely positioned within the bore of the coiled tubing. Conventional configurations of components (such as sensors) within coiled tubing strings may be difficult or cumbersome to deploy within the coiled tubing. As such, an improved means of preparing a coiled tubing string and/or securing sensors within the coiled tubing string is needed.

     Disclosed herein are embodiments of a coiled tubing servicing tool (CTST), a coiled tubing servicing system comprising a CTST, and methods of using the same. In an embodiment, a CTST may be employed to perform one or more coiled tubing servicing operations, for example, to provide access to one or more components (e.g., one or more sensors) disposed within a flowbore of a length of coiled tubing. For example, in an embodiment, such a length of coiled tubing may be employed within a wellbore environment for purposes of monitoring such a wellbore. The coiled tubing may be assembled to a given specification (e.g., having a quantity of sensors, types of sensors, sensor locations within the coiled tubing, length of coiled tubing, etc.). In such an embodiment, the plurality of wires, the plurality of sensors and/or other components may be positioned and secured within the length of coiled tubing. Additionally, the length of coiled tubing may require access ports, for example, to expose the sensors to wellbore conditions and/or wellbore fluids. In such an embodiment, the CTST may be used to locate one or more components (e.g., a sensor or other equipment) disposed within a flowbore of a length of coiled tubing and/or to provide access to the components by providing a route of access between the flowbore of the length of coiled tubing and the exterior of the length of coiled tubing. Alternatively, the CTST may be used to machine, to service, to repair, and/or to perform any other suitable coiled tubing servicing operation with respect one or more portions of a length of coiled tubing as would be appreciated by one of ordinary skill in the art upon viewing this disclosure. 
     In the embodiment of  FIG. 1 , the CTST  500  may generally comprise a servicing cart  100  and a servicing fixture  200 , as will be disclosed herein. 
     In an embodiment, the servicing cart  100  may be configured to provide access to a portion of a length of coiled tubing (for example, about 360 degrees of access with respect to the longitudinal axis  600  of the coiled tubing). For example, in the embodiment of  FIG. 1 , the servicing cart  100  may be configured to suspend, support, and/or secure at least a portion of a length of coiled tubing  300 . Additionally, in an embodiment, the servicing cart  100  may be configured to support the servicing fixture  200 . In an embodiment, the servicing cart  100  may be configured to be mobile and repositionable along the length of coiled tubing  300 , as will be disclosed herein. In an embodiment, as illustrated in  FIG. 2 , the servicing cart  100  may generally comprise a positioning platform  104  and two or more support frames  106 . 
     In an embodiment, the positioning platform  104  may generally comprise a frame (e.g., a rectangular frame, an H frame, an X frame, etc.), for example, which may be supported by a plurality of wheels  102  (e.g., casters, rollers, etc.). Alternatively, the frame may be supported by a plurality of legs (e.g., adjustable legs or the like). In an embodiment, the positioning platform  104  may be configured to move (e.g., to roll) the servicing cart  100  to and from (and underneath) the length of coiled tubing  300 . Additionally, in an embodiment, one or more of the wheels  102  may be configured to be lockable, and thereby substantially restrict the motion of the positioning platform  104 . 
     In an embodiment, the supporting frames  106  may be positioned and/or configured to support a portion of the coiled tubing  300  and/or a servicing fixture  200 , as will be disclosed herein. In an embodiment, the supporting frames  106  may be disposed on to the servicing cart  100 , for example, about perpendicular to (e.g., upright with respect to) the positioning platform  104 . In an embodiment, the servicing cart  100  comprises 2 pairs of supporting frames  106  with each pair of supporting frames  106  having space there between. For example, in an embodiment, the supporting frames  106  may be positioned about two feet from each another, alternatively, about three feet from each another, alternatively, about four feet from each another, alternatively, any other suitable distance from each other as would be appreciated by one of ordinary skill in the art upon viewing this disclosure. Additionally, in an embodiment, the supporting frames  106  may provide suitable clearance to rotate and/or position a servicing fixture about the coiled tubing  300 , for example, thereby providing access to the coiled tubing, as will be disclosed herein. In an embodiment, the supporting frames  106  may be configured to have a fixed vertical height, as illustrated in  FIG. 2 . In an alternative embodiment, the supporting frames  106  may be configured to have an adjustable vertical height. For example, in an embodiment, the supporting frames  106  may comprise one or more telescoping portions (e.g., concentric hydraulic pistons) which telescopically extend to increase the height of the support frames  106  and which telescopically retract to decrease the height of the supporting frames  106 . In an additional or alternative embodiment, the supporting frames  106  may be configured to have portions which move with respect to one another via gears, tracks, ratchets, screws, scissors, etc., for example, a vertical height mechanism may be configured to move portions of the supporting frames  106 . 
     In an embodiment, as illustrated in  FIG. 2 , an upper portion of the supporting frames  106  may comprise a pipe guide  107 , for example, a groove, a notch, a cradle, a slot, a channel, or any other suitable structure as would be appreciated by one of ordinary skill in the arts upon viewing this disclosure, or combinations thereof.

     In an additional or alternative embodiment, the CTST  500  may be configured to employ any other suitable servicing tool which may be utilized to perform one or more coiled tubing servicing operations as would be appreciated by one of ordinary skill in the art upon viewing this disclosure. For example, in an embodiment, the x-ray assembly  400  and the drilling press assembly  402  may be mounted on a common assembly opposite each other and may counter balance each other. 
     In an embodiment, a coiled tubing servicing method utilizing a CTST, such as the CTST  500 , is disclosed herein. Such a method may comprise preparing a length of coiled tubing, preparing a CTST  500 , locating one or more components within the axial flowbore of the length of coiled tubing, and providing access to the one or more components within the axial flowbore of the length of coiled tubing. In an additional embodiment, the coiled tubing servicing method may further comprise disassembling the CTST  500 , repositioning the CTST  500 , locating one or more additional components within the axial flowbore of the length of coiled tubing, and providing access to the one or more components within the axial flowbore of the length of coiled tubing. Still further, the coiled tubing servicing method may further comprise respooling the coiled tubing, positioning the coiled tubing within a wellbore and/or casing string, and logging data from the one or more sensors of the coiled tubing. 
     In an embodiment, a length of coiled tubing may be prepared, for example, for the purpose of monitoring a wellbore and/or any other wellbore servicing operation. For example, in an embodiment, preparing a length of coiled tubing  300  may generally comprise the sub-steps of providing a length of coiled tubing  300 , disposing one or more data conduits within the axial flowbore of the coiled tubing  300 , affixing one or more components (e.g., a sensor) to the one or more data conduits, and positioning the one or more components (e.g., a sensor) within the axial flowbore of the coiled tubing  300 . 
     In an embodiment, a length of coiled tubing  300  may be unspooled and/or extended, for example, by uncoiling the length of coiled tubing  300  onto a suitable surface (e.g., an airplane runway, a street, a field, an assembly belt, etc.). In an embodiment, the length of coiled tubing  300  may be measured and/or cut to a desired length, for example, a length associated with a desired monitoring location within a wellbore. In an embodiment, the two or more data conduits (e.g., electrical conducting wires and/or fiber-optic cables) may be passed through the axial flowbore of the length of coiled tubing  300 , for example, from a heel end (e.g., an upper end, when disposed within the wellbore) toward a toe end (e.g., a lower end, when disposed within the wellbore) of the coiled tubing  300  by any suitable method. For example, in an embodiment, the two or more data conduits may be pulled through the axial flowbore of the coiled tubing  300  with a cable or by a suitable, mechanical means. In an embodiment, the two or more components (e.g., two or more sensors such as temperature and/or pressure sensors) may be attached to the two or more data conduits. For example, in an embodiment, a first sensor may be attached (e.g., via a hardwired electrical connection) to a first data conduit (e.g., a copper wire) and a second sensor may be attached (e.g., via a hardwired electrical connection) to a second wire data conduit (e.g., a copper wire). Additionally, in an embodiment, for example, following attachment of the sensors to the data conduits, the two or more data conduits and two or more sensors may be retracted (e.g., pulled) within the axial flowbore (e.g., in a direction from the toe towards the heel) of the coiled tubing  300  and/or may be positioned within the axial flowbore of the coiled tubing  300  (e.g., placed at a desired location along the length of coiled tubing  300 ).

As used herein, the term “precisely” refers to a range of proximity to the one or more components (e.g., a sensor), for example, within a range of about plus or minus about 6 in, 5 in, 4 in, 3 in, 2 in, 1 in, 0.5 in, 0.1 in, etc. In such an embodiment, the x-ray assembly  400  may be installed onto the equipment perches  212  of the servicing fixture  200 . For example, in an embodiment as illustrated in  FIG. 3A , the x-ray source  218  (e.g., a non-radioactive digital x-ray source) may be attached to and/or installed onto the first equipment perch  212   a  and the x-ray receptor  219  may be attached to and/or installed onto the second equipment perch  212   b . Additionally, in an embodiment, the x-ray receptor  219  may be further supported by the supporting arms  209 . In an embodiment, the x-ray assembly  400  may be positioned along the longitudinal axis  600  of the coiled tubing  300  via the linear actuators  206   a  and/or the rails  206   c  and/or may be positioned radially about the longitudinal axis  600  of the coiled tubing  300  via the radial actuators  206   b . For example, in an embodiment, the x-ray assembly  400  may be positioned adjacent to and/or proximate to a portion of the coiled tubing to be inspected, for example, as indicated by Eddy meters or the like. In an embodiment, the x-ray assembly  400  may provide an x-ray image of the interior of a portion of the coiled tubing  300 , for example, for the purpose of precisely locating the one or more components disposed within the axial flowbore of the coiled tubing  300 . Additionally, in an embodiment, the x-ray assembly  400  may be repositioned, as needed, to locate the one or more components disposed within the axial flowbore of the coiled tubing  300 . For example, in an embodiment, the x-ray assembly  400  may iteratively locate a component disposed within the axial flowbore of the coiled tubing  300 , for example, via providing an x-ray image, inspecting the x-ray image, readjusting the longitudinal and/or radial position of the x-ray assembly  400 , and repeating one or more steps as needed to precisely locate the position and/or orientation of the component (e.g., the sensor). In an embodiment, the coiled tubing  300  may be marked or otherwise denoted to indicate the precise location and/or orientation of the one or more components disposed within the axial flowbore of the coiled tubing  300 . In an additional or alternative embodiment, upon precisely locating the one or more components disposed within the axial flowbore of the coiled tubing  300 , the x-ray assembly  400  may be removed from the servicing fixture  200 . 
     In an embodiment, a drilling assembly  402  may be employed to provide access to the axial flow bore of the coiled tubing  300 . In such an embodiment, the drilling assembly  402  may be installed onto one of the equipment perches  212  of the servicing fixture  200 . For example, in an embodiment as illustrated in  FIG. 3B , the drilling press  214  (e.g., a cordless magnetic drill press) may be attached to and/or installed onto the first equipment perch  212   a . In an additional embodiment, a counter weight may be attached to and/or installed onto a second equipment perch  212   b , for example, for the purpose of stabilizing the servicing fixture  200  from rotating radially about the longitudinal axis  600 . In an embodiment, the drilling assembly  402  and/or servicing fixture  200  may remain in a previously configured position and/or orientation with respect to the coiled tubing  300 . For example, in an embodiment, the previously configured position and/or orientation with respect to the coiled tubing  300  may be established and/or determined by the x-ray assembly  400  (e.g., as previously and precisely marked on the coiled tubing  300 ). In an additional or alternative embodiment, the drilling assembly  402  may be positioned along the longitudinal axis  600  of the coiled tubing  300  via the linear actuators  206   a  and/or the rails  206   c  and/or may be positioned radially about the longitudinal axis  600  of the coiled tubing  300  via the radial actuators  206   b . For example, the drilling assembly  402  may be positioned adjacent to and/or proximate to a portion of the coiled tubing  300  to be operated on (e.g., drilled). In an embodiment, the drilling assembly  402  may provide a route of access (e.g., via drilling one or more holes) to the interior of the coiled tubing  300  and/or to the one or more components disposed within the axial flowbore of the coiled tubing  300 . For example, in an embodiment, the drilling assembly  402  may be configured to drill one or more holes to a predetermined depth into the coiled tubing  300  at a precise location previously determined and marked. Additionally, in an embodiment, the drilling assembly  402  may be repositioned, as needed, to provide additional access (e.g., via drilling one or more additional holes) to the one or more components disposed within the axial bore of the coiled tubing  300  at a precise location previously determined and marked. 
     In an embodiment, the CTST  500  may be disassembled to perform one or more additional coiled tubing servicing operations. For example, in an embodiment, the one or more servicing tools (e.g., the x-ray assembly  400  and/or the drilling assembly  402 ) may be removed from the servicing fixture  200 . Additionally, in an embodiment, the servicing fixture  200  may be removed from the servicing cart  100  and/or the coiled tubing  300 . In an embodiment, the coiled tubing  300  may be removed from the servicing cart  100 , for example, by removing the restraining mechanisms  108  and removing the coiled tubing  300  from the pipe guides  107  of the servicing cart  100 . In an embodiment, where the length of coiled tubing  300  requires more than one coiled tubing servicing operations, the CTST  500  may be repositioned and a coiled tubing servicing method may be performed, similar to previously disclosed, for example, to provide fluid communication to additional sensors at additional locations along the coiled tubing  300 . Additionally, in an embodiment, following servicing the coiled tubing  300 , the coiled tubing  300  may be respooled and/or transported to a wellbore site. In such an embodiment, the coiled tubing  300  may be positioned within a casing string and/or wellbore and in fluid communication with a wellbore fluid, wherein sensors disposed within the coiled tubing  300  are in fluid communication with ambient wellbore conditions vie one or more holes drilled into the coiled tubing  300 . For example, in an embodiment, the coiled tubing  300  may be employed to monitor one or more wellbore conditions (e.g., temperature, pressure, etc.). 
     In an embodiment, a CTST  500 , a system comprising a CTST  500 , and/or a coiled tubing servicing method employing such a system and/or CTST  500 , as disclosed herein or in some portion thereof, may be advantageously employed to precisely locate one or more components within the axial flowbore of a length of coiled tubing  300  and/or to provide access to the one or more components within the axial flowbore of a length of coiled tubing  300 . For example, in an embodiment, a CTST  500  provide the ability to precisely and iteratively locate one or more components within the axial flowbore via employing a coiled tubing servicing method, such as previously disclosed, thereby allowing for accurate detection and/or servicing of the coiled tubing. In an embodiment, a CTST like CTST  500  enables multiple coiled tubing servicing operations (e.g., inspecting, marking, x-raying, drilling, etc.) to be performed while securing and/or isolating at least a portion of the coiled tubing  300 . In an embodiment, the CTST  500  enables servicing tools to be positioned along the longitudinal axis  600  of the coiled tubing  300  and about 360 degrees of rotation about longitudinal axis  600  of the coiled tubing  300  for performing coiled tubing servicing operations. Such methods of servicing a coiled tubing  300 , as previously disclosed, may provide a way to secure a portion of the coiled tubing  300  and to operate with about 360 degrees of freedom about and/or along the longitudinal axis  600  of a length of coiled tubing  300 . Conventional methods may not provide an apparatus configurable to use a plurality servicing equipment components to perform a coiled tubing servicing operation. Therefore, the methods disclosed herein provide a means by which to locate one or more components within the axial bore of a length of coiled tubing  300 , to provide access to the one or more components within the axial bore of a length of coiled tubing  300 , and/or to perform additional coiled tubing servicing operations, as needed.
