This invention provides oilfield spooled coiled tubing production and completion strings assembled at the surface to include sensors and one or more controlled devices which can be tested from a remote location. The devices may have upsets in the coiled tubing. The strings preferably include conductors and hydraulic lines in the coiled tubing. The conductors provide power and data communication between the sensors, devices and surface instrumentation. The coiled tubing strings are preferably tested at the assembly site and transported to the well site one reels. The coiled tubing strings are inserted and retrieved from the wellbores utilizing an adjustable opening injector head system. This invention also provides method of making electro-coiled-tubing wherein upper and lower adapters are connected to the coiled tubing and tested prior to transporting the string to the wellbore. The string preferably includes pressure barriers at both ends of the string. The string also includes a power line, hydraulic lines, data and communication lines and the desired sensors and devices for use with an electrical submersible pump.
