Claim 7:
8. The system of claim 7, further comprising:
a reel that feeds the coiled tubing to the injector assembly;
one or more first hydraulic motors configured to drive rotation of the reel;
one or more second hydraulic motors configured to drive rotation of the pair of endless drive chains and thereby longitudinally move the coiled tubing;
a power source that provides hydraulic fluid for the one or more first and second hydraulic motors; and
