Patent ID: 7028781

Claim:
A system for injecting or withdrawing a fluid into or from a well, comprising: (a) an injector vehicle operable to position a flexible tubing into the well, the injector vehicle having a longitudinal center axis; and (b) 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 prior to and 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, wherein the axis of rotation of the at least one spool is substantially parallel to the longitudinal center axis of the tubing supply vehicle, and wherein the tubing supply vehicle comprises a spool displacement device operable to displace 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.
