Deep-well, continuous-coiled-tubing apparatus and method of use

A method for supplying flexible tubing to a well, comprising:

• (a) providing (i) an injector vehicle operable to position the flexible tubing into the well, the injector vehicle having a longitudinal center axis, and (ii) a tubing supply vehicle having a longitudinal center axis and operable to provide the flexible tubing to the injector vehicle for positioning in the well, wherein the flexible tubing is mounted on at least one spool for transportation to the well, the at least one spool having an axis of rotation, wherein the longitudinal center axis of the injector vehicle is transverse to the axis of rotation of the at least one spool and transverse to the longitudinal center axis of the tubing supply vehicle, and wherein the axis of rotation of the at least one spool is substantially coplanar to the longitudinal center axis of the tubing supply vehicle;
• (b) unspooling the flexible tubing from the at least one spool, wherein the unspooling step comprises the substep of displacing the spool back-and-forth along the longitudinal center axis of the tubing supply vehicle to maintain an angular orientation of the flexible tubing relative to the longitudinal center axis of the injector vehicle at an angle less than a selected angle to inhibit bending of the flexible tubing;
• (c) feeding the unspooled flexible tubing to the injector vehicle;
• and
• (d) introducing the unspooled flexible tubing into the well.
