Time-Saving Wellheads
Pressure Control SH2 Split Speedhead
™
System
The SH2 Split Speedhead™ System oers signicant time-
saving and safety-enhancing advantages over conventional
wellheads and is compatible with today’s advanced drilling
methods. The speedhead is a multi-bowl system, supporting
and sealing two strings of pipe in a single head. Safety is
improved and installation time reduced by running, landing
and sealing the two strings without removing the BOP stack.
The system will save approximately 17 hours of rig time: 12
hours of BOP manipulation and 5 hours by using a mandrel
hanger/packo rather than a slip hanger. By using a weldless
casing connector (Surelok or LRC), an additional 8 hours can
be saved.
The dierence between a conventional multi-bowl and an SH2
speedhead system is the wellhead housing. The SH2 housing
consists of two pieces — a lower housing and an upper
housing — installed as one unit. If the intermediate casing
becomes stuck, preventing the mandrel hanger from landing
in the bowl, then the two housings can be separated. Then the
emergency slip-style casing hanger can be easily installed and
the casing cut using conventional installation methods.
