Claim:
A flow completion apparatus for controlling the flow of fluid through a tubing string which extends into a well bore, the flow completion apparatus comprising: a tubing spool which is positioned over the well bore and which includes a central bore that extends axially therethrough, a production outlet that communicates with the central bore, and an annulus passageway that communicates with a tubing annulus surrounding the tubing string; a tubing hanger which is supported in the central bore and is connected to an upper end of the tubing string, the tubing hanger including a production bore that extends axially therethrough and a production passageway that communicates between the production bore and the production outlet; and an annular seal which is positioned between the tubing hanger and the central bore above the production passageway; wherein the tubing spool further comprises a workover passageway which provides for communication between the annulus passageway and a portion of the central bore that is located below the top of the tubing hanger; and wherein the tubing hanger further comprises an annulus bore which extends between the workover passageway and the top of the tubing hanger; whereby fluid communication between the tubing annulus and the top of the tubing hanger may be established through the annulus passageway, the workover passageway and the annulus bore.
