ABSTRACT:
A method and apparatus for the installation of cable into a reel of coiled tubing includes a cable injector. The cable injector comprises a capstan drive within a pressure housing. In a preferred embodiment, the capstan comprises a drive wheel that is enclosed within the pressure housing and the pressure housing is made up of a pair of seal plates or flanges with a seal ring between them. A drive shaft penetrates one of the flanges. This arrangement minimizes the size of a rotating seal in the pressure housing.
