Abstract:
Method, apparatus and a system is provided for injecting carrier sleeves into a wellbore. A selected carrier sleeve is aligned in an injector bore restricted therein from free fall and preventing a subsequent sleeve from indexing into the bore from a magazine of sleeves. The sleeve can be restricted from free fall from the bore using an annular restrictor. The selected sleeve is forcibly displaced from the injector bore into a staging bore, as part of an contiguous axial bore, that is isolated from the wellbore. The staging bore is fluidly isolated from the injector bore. The pressure in the staging bore is equalized with the wellbore and then opened to the wellbore for launching the sleeve. The staging bore can be isolated from the injection bore by valve or isolation mandrel sealably moveable within the axial bore.

Claim (Index 1):
A sleeve injector for injecting carrier sleeves into an axial bore of a wellhead contiguous with a wellbore having sleeve-actuated devices therein, comprising:\n an injector head adapted to be supported by the wellhead, the injector head having an injector bore therethrough in fluid communication with the axial bore; at least one sleeve magazine has an aperture in communication with the injector bore, each magazine storing at least one sleeve, each of the at least one sleeve magazine having an actuator operable for aligning a selected sleeve of the at least one sleeve with the injector bore; and a fall restrictor for preventing premature free fall of a carrier sleeve aligned in the injector bore.
