Abstract
An apparatus for moving tubing through a borehole is disclosed. The apparatus includes a surface injector assembly and a downhole injector assembly with a driving mechanism to move the tubing through the borehole, an anchoring system for securing the downhole injector assembly downhole to a cased portion of a borehole wall and connections for receiving a power supply form the surface. A method of moving tubing through a borehole is also disclosed. The method involves attaching a downhole injector assembly to a cased portion of a borehole wall sufficiently downhole such that the downhole injector assembly can supply weight to a drilling assembly, and injecting tubing through the borehole using the downhole injector assembly.
