SCH1 Casing Head
Where risers or rig floor limitations drive you to welding on a conventional casing head, the SCH1 Casing Head is a cost-effective alternative. Run with the surface casing string through the riser and using normal cementing operations, the SCH1 casing head is immediately available for BOP nipple-up when the riser is removed. Eliminating the casing head weld:
- improves safety,
- saves valuable rig time, and
- facilitates multi-well drilling programs from a common location by eliminating "hot" operations.
With the pre-installed pup joint (nipple), no wait-on-cement time and the use of the DVC speed connector, our customers can expect to save in excess of 10 hours of valuable rig time, per well.
