ABSTRACT:
A system and method for injecting or withdrawing a fluid into or from a well includes an injector vehicle having a longitudinal axis and operable to position tubing into the well. The system also includes a tubing supply vehicle operable to provide the tubing to the injector vehicle for positioning in the well. In one aspect of the invention, the tubing is mounted on at least one spool, wherein the longitudinal axis of the injector vehicle is transverse to an axis of rotation of the spool and transverse to a longitudinal axis of the tubing supply vehicle. In a separate aspect of the invention, a spiral guide is used to transition tubing during spooling and unspooling between a plurality of empty and full spools. In yet a separate aspect of the invention, a spool is vertically adjustable to allow rotation of the spool during spooling and unspooling.
