The SH3 Speedhead™ System takes multi-bowl technology
one step further than ever before. By landing two strings
of pipe in one compact forged housing, the SH3 system
eliminates one complete BOP nipple-down/nipple-up thereby
saving significant rig time. Additionally, specially designed
service tools can reduce installation time even further. The
time saved (estimated at approximately 17 hours) makes this
product a cost-effective alternative to conventional spool type
surface wellheads.
Compared to conventional wellheads, the SH3 wellhead
Compared to conventional wellheads, the SH3 wellhead
improves safety by reducing the number of potential leak
paths. The system completely eliminates one major flange
connection and replaces all external lockdown screws with
internal retaining rings similar to those used on subsea
systems.
In order to take full advantage of the time-saving capabilities
In order to take full advantage of the time-saving capabilities
of this system, the SH3 system is normally recommended for
applications where the risk of a casing becoming stuck is
very low.
