The Seaboard WS-CMB-22 multi-bowl wellhead assembly decreases the costs associated with surface drilling and production by suspending multiple casing strings in one wellhead. Its compact full-bore design reduces the number of times the blow out preventer connection is broken, eliminating non-productive time.
The fluted lower casing hanger allows ample bypass for circulating mud and cement. The seal assembly, which lands on the flutes, also acts as a support for the upper hanger. No welding is required.
All running and retrieving tools run on the casing, and emergency suspension systems are available for the lower hanger. Offered in standard and customized assemblies, the conductor hanger seals may be re-energized as needed and tested externally once landed. The surface casing hanger may be landed before cementing and its annular seal may also be re-energized.
Compatible with the most common flange sizes, the reliable Seaboard WS-MB-22 multi-bowl withstands pressures from 5, 000 psi to 10, 000 psi.
