<p>A horizontal spool tree assembly (10) is provided for supporting a production tubing string (22) within a well below a BOP. 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 workever 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.</p> |
