Portable foam injection system

Abstract

A portable system is provided for foam injection. The system includes two or more tanks of foam-producing components; a pump associated with each of the two or more tanks; a length of modified conduit; a conduit interjector; and a wireline system. The conduit is pushable by the injector into cavities to be injected with foam and extractable therefrom. A method is further provided for foam injection at a remote location. The method includes the steps of transporting the portable system to the remote location; injecting the modified conduit into a distal end of a cavity to be foamed; pumping the foam-producing components from the two or more tanks via the pumps, each through a component line running through the modified conduit; forming and expansion of a foam by the foam-producing components exiting a nozzle of the modified conduit and contacting one another; and pulling the modified conduit from the distal end of the cavity to a proximal end of the cavity, while foaming the cavity from the distal end to the proximal end as the modified cavity is pulled.
