injector maximizes the distance that fluid travels after exiting its openings before reaching the casing 14 as compared to a conventional choke injector that is concentric with respect to the longitudinal axis of the wellbore due to this additional distance that the exiting fluid travels the velocity of the fluid is reduced thereby reducing if not preventing erosion of the casing 14 due to contact of the fluid with the casing 14 as depicted in fig1 the casing 14 generally lines a wellbore 12 which receives the string 1 6 and the choke injector assembly 20 the choke injector is formed from at least an inner choke sleeve not depicted in fig1 and depicted as reference numeral u201c 50 u201d in fig2 6 and an outer tubular choke housing 22 the inner choke sleeve is designed to longitudinally travel inside the outer choke housing 22 to regulate the outward fluid flow from the choke injector the inner choke sleeve includes radial ports or openings that when exposed through one or more windows 24 one window 24 being depicted in fig1 and multiple windows 24 being depicted in fig4 of the outer choke housing 22 inject fluid into the well the number of openings that are exposed through the window.
