LSH Land Speedhead™ System
The LSH Land Speedhead™ System is designed for use as a two-stage starting head, combining the casing head and casing spool into a single housing. The BOP stack is made up to the starting head before drilling commences and is not removed until two strings of casing have been run. By landing two casing strings in one compact forged housing, the LSH system eliminates one complete BOP nipple-down/nipple-up thereby saving significant rig time and improving safety.
The LSH system offers an economical alternative to the SH2 or SH3 speedhead systems for less demanding applications.
