T he Cameron MBS Multi-Bowl Wellhead System is acompact, unitized wellhead which can be used asan alternative to conventional wellhead systems in

onshore and platform applications. The MBS Wellheadoffers the following advantages over conventional systems:

• The lower and upper casing heads are installed as a single unit, saving installation time.

• The casing and tubing can be installed, landed andsealed through the BOP stack, increasing safety and saving rig time normally required to remove and reinstall the BOP stack during conventional wellheadinstallations.

• Uses many conventional wellhead components and practices.

Components of the MBS Wellhead System are based onfield-proven technology and offer a range of featuresincluding:

Lower Casing Head

• The lower casing head incorporates a slip-on weld bottom connection with a single O-ring to seal betweenthe casing stub and the casing head inside diameter.

• The lower casing head is available with line pipe threaded, flanged or studded outlets.

• The casing head incorporates a straight-bore designwith a 45° load shoulder for casing hanger support.This design minimizes hoop load on the housing, provides a high hanging capacity and reduces the risk of bowl damage due to drill stem rotation.

Upper Casing Spool

• The upper casing spool is a straight-bore design.

• The casing spool includes two sets of type N lockscrewsto lockdown wellhead components. These lockscrewsare designed with the packing in front of the threads toprevent contamination of the threads by wellbore fluid.

• The spool is available with studded outlets.

Casing Hanger

• The MBS Wellhead casing hanger is a high-capacity,mandrel-type hanger which is rated to the full jointstrength of the suspended casing.

• The hanger is designed with integral flutes which allowcement returns to pass up through the BOP stack.

Pack-off Bushing

• The MBS Wellhead pack-off bushing lands on the casinghanger to suspend and seal the intermediate casingstring(s).

• The inner seal on the bushing is a D seal which is ener-gized by plastic packing. This seal can be reenergized, ifnecessary, throughout the life of the well. The outer sealis radially energized.

Tubing Hangers

• The MBS Wellhead tubing hanger lands on the pack-offbushing and is locked in place with N lockdown screws.

• Several alternative tubing hangers are available includ-ing the coupling (HT, HT-2), tubingless (TLC), mandrel(CXS, T), and dual (MB-CDT and MB-TLC). Controlline options are available for most applications. A com-parison of these tubing hangers is available on the MBSTubing Hanger Comparison chart.

Tubing Head Adapter

• The MBS tubing head adapter provides the connectionpoint for the Christmas Tree. It is available in severaltypes to fit individual applications.

Emergency Slip and Seal Assemblies

• In the event that casing becomes stuck and slips must beset, the upper casing spool may be lifted to install a slip-type hanger, cut off the casing and install the emergencypack-off bushing assembly. This feature eliminates theexpensive, time consuming process of cutting pipeinside the head with internal casing cutters.

Auxiliary Equipment

• The MBS Wellhead System has a complement of installa-tion tools including BOP test plugs, wear bushings andhandling tools.
