Abstract: An adjustable guide, includes two or more mechanisms each having a rotatable retaining element containing a retaining groove with a variable radius in its perimeter surface. The grooves form a guidance path to control the lateral, i.e. non-axial, motion of a long bar moving along a longitudinal axis during a production process. The diameter of the guidance path varies according to the variable radii of the grooves.

Abstract: A tubing guide for directing coiled tubing through an injector apparatus and into a well. The tubing guide comprises a frame, which is also referred to as a tubing carrier, extending from a base.

Abstract: The injector of the invention provides a means and method for injecting either coiled tubing or conventional stalked tubing into and from a well by developing axial forces in the tubing. The curvature of the coiled tubing is simultaneously selectably altered on the opposite side of the injector from the wellhead.
