Time-Saving Wellheads
Pressure Control SH2 Split Speedhead
™
 System
The SH2 Split Speedhead™ System offers significant 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/packoff rather than a slip hanger. By using a weldless 
casing connector (Surelok or LRC), an additional 8 hours can 
be saved.
The difference 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.
