The spool body 12 includes a laterally extending passageway 36 which is in fluid communication with a similar laterally extending passageway 34 provided in a tubing hanger 20. The tubing hanger includes a central bore for fluid communication with the production tubing string, and a workover flow path 30 extending axially through the tubing hanger, with a workover valve 32 provided for controlling the fluid flow in the workover passageway. An annulus port 70 extends laterally through the spool body, and an annulus valve 72 controls fluid flow through the annulus port. |
