ABSTRACT:
A horizontal spool tree wellhead system10utilizes a casing18, 19installed in a well bore and a wellhead housing20at the upper end of the casing. A spool23of the horizontal tree22is connected to the upper end of the wellhead housing, and includes at least one radially extending side port. The BOP28is also installed at the upper end of the housing with a bore aligned with the wellhead housing bore. After drilling the well, the casing string19carrying a casing hanger42may be lowered through the bores of the BOP, the spool tree, and the wellhead housing and into the well. An orientation/isolation sleeve60may be installed in a predetermined rotational orientation with the spool tree. A tubing hanger70having a side port is landed onto the orientation sleeve and is automatically oriented to align the tubing hanger side port with the spool side port.
