     BACKGROUND 
       [0002]    In the hydrocarbon recovery industry, a clear desire has always been and always will be efficiency. Efficiency translates into greater profits for the well operator. Included in the repertoire for efficiency are downhole tools that benefit from power and signal from remote locations on a real time basis. Such has been provided in coiled tubing applications by running a wireline through the inside of a coiled tubing string. While this works for some applications, it suffers from disadvantages that in some cases are merely repressive of well activity and in other cases are preventative. One example of a downhole operation that is prevented by the use of a wireline in a coiled tubing is the mechanical setting of a completion using a tripping ball. This is because a tripping ball is likely to be impeded in reaching its intended destination by the wireline itself. The impedance is due to the girth of the wireline relative to the total inside dimensional area of the tubing string and or birdcaging of the wireline. Commonly, in order to remedy this situation, a coiled tubing run for drilling purposes is made using a wireline therein and then a coiled tubing conveyed completion run is made using coiled tubing without the wireline so that a tripping ball may be reliably dropped. While the method is effective it lacks efficiency.

     DETAILED DESCRIPTION 
       [0009]    It is common with existing systems to provide wireline slack in an amount approximating an anticipated amount of stretch that a coiled tubing will experience during use. This is because the wireline does not have similar stretch characteristics to the coiled tubing. Thus, if wireline slack is not pumped into the coiled tubing, the wireline is likely to become disengaged from a bottom hole assembly (BHA), break or both. Common usage then is to pump excess wireline into the coiled tubing. This requires work at the surface to pump the slack, machinery wear and tear, and time. The wireline slack is to be evenly distributed inside the coiled tubing to maintain the coupling with the BHA intact. Further, if wireline slack migrates to a particular area in the string, i.e. it is not distributed along the string; it can cause the outer armors of the wireline to “birdcage”. This is detrimental both because it prevents passage of other tools through the coiled tubing and because it can cause the wireline, therebelow, to become taught to the BHA, undermining the point of the slack in the first place. This condition necessitates a common art practice of back pumping the wireline over time to redistribute the same, thereby avoiding birdcaging. This operation is commonly known as “slack management”. The back pumping operation requires time and an interruption in normal circulation that slows the overall process being carried out in the wellbore. In addition, the sheer size of typical wireline is an impediment to running other tools through the tubing. 
         [0010]    Referring to  FIG. 1 , a schematic illustration depicts the condition of a section of a coiled tubing string  112  and signal conductor  110  in accordance with the teaching hereof. In  FIG. 1 , it will be appreciated that the signal conductor  110  is significantly smaller in outside dimensions than an inner dimension of the coiled tubing  112 . In one iteration, the conductor  110  is 3/16 inch in diameter. This leaves more of the inside dimension area of the coiled tubing string  112  available for other purposes including running other tools therethrough. For example, a coiled tubing configured as taught herein is employable for running and cementing liners and for subsequent disconnect of liners, among other things. These processes can be accomplished, for example, with tripping balls dropped from the surface, etc. Moreover, it will immediately be appreciated that the signal conductor  110  is positioned substantially in parallel with the coiled tubing  112 . The signal conductor  110  has an elongation factor of about 45 percent, which factor is to be at least as great as an elongation factor of the coiled tubing string  112  in which the signal conductor  110  is intended to be disposed. This facilitates the parallel condition of the signal conductor  110  throughout the length of the coiled tubing string  112 . Slack is not needed in the configuration as taught and consequently, slack management is not needed. One of ordinary skill in the art having read the foregoing paragraph will quickly realize that the configuration taught herein thus avoids wear and tear on injecting machines, reduces time of installation, substantially eliminates “birdcaging” and thereby improves the function of coiled tubing conveyed bottom hole assemblies. Because “birdcaging” does not form, there is no need to engage in the prior art required back pumping of the wireline. 
         [0011]    Both the size of the conductor and the lack of slack facilitate the ability to run other tools through the coiled tubing string  112 . Such tools include tripping balls and other devices for completion operations. The ability to run such other tools also means that drilling and completion can be accomplished using a single coiled tubing rather than in at least two as has typically been done heretofore. 
         [0012]    Referring to  FIG. 2 , the signal conductor  110  comprises an electrical signal carrier  120  loosely disposed within a control line  130 , the control line  130  comprising, in one embodiment, Incoloy® (nickel-chromium alloy) material. The signal carrier  120  is composed of a material capable of carrying either or both of power and data between a remote location and the BHA  114 , such as a copper wire, for example. This allows for the BHA  114  to be powered by the signal conductor  110  and send data between the remote location such as the surface and itself while facilitating the benefits set forth above. In addition, the loose disposition of the signal carrier  120  within the control line  130  allows for pressure transmission as well as signal transmission. Pressure actuated features of the BHA  114  are also enabled using the signal conductor  110 . 
         [0013]    While preferred embodiments have been shown and described, modifications and substitutions may be made thereto without departing from the spirit and scope of the invention. Accordingly, it is to be understood that the present invention has been described by way of illustrations and not limitation.
