Exact Adjustable Wellhead System The Exact* adjustable wellhead system was developed specifically to reduce rig installation time and with safety in mind. The system is suitable for jackup drilling up to 10,000-psi working pressure where adjustment from mudline to surface is required for exploration and predrilling. The Exact-15 system is rated for 15,000-psi working pressure and is suitable for HPHT applications. Reduced installation times, no separate tension equipment required, and availability for full-sized and slimhole casing programs are among the benefits of Exact systems. Offshore...

Featuring a patented washsleeve design that eliminates pipe rotation, the Centric* C-15 mudline suspension wellhead system is reliable in high-pressure, high-load mudline applications. The system enables landing high casing loads, increasing system versatility, and is capable of pressure ratings up to 15,000 psi. A stackdown configuration eliminates debris traps, and a unique split-cage design prevents damage to the cage during compression. The Centric C-15 EX wellhead system is a standard offering for pressure ratings less than 10,000 psi. It features a deep stackdown design with separate...

Cameron provides a suite of drilling equipment designed to reduce installation time and enhance safety. 6 | SURFACE SYSTEMS TECHNOLOGY | SHALLOW-WATER EXPLORATION WELLHEAD SYSTEMS

Drilling Cameron wellhead systems range from conventional to application-specific systems for geothermal wells, jackup rigs, unconventional plays, and more. designed to reduce installation time and enhance safety, they use trims and proprietary sealing technologies for expected well conditions. Cameron was the first to engineer surface wellhead systems rated to 30,000 psi and 450 degF and qualified per Api 6A Appendix F.

IC Conventional Wellhead System The versatile IC* conventional wellhead system product line incorporates a wide range of slip-type and mandrel casing hangers and packoffs, including the automatic slip-type hanger, which uses casing weight to energize the annular seal. Rated to 10,000 psi, the IC wellhead system can thus be configured to meet many service conditions. It incorporates the lower casing head housing and hanger as well as the subsequent casing head spools and hangers. It is compatible with all our tubing spool and hanger configurations. Offshore and onshore drilling and...

Drill-Through Wellhead System Drilling The drill-through wellhead system maximizes efficiency by streamlining drilling operations. Well control is achieved with one BOP rig-up, resulting in safer drilling activities and providing significant time savings that reduce rig costs. Mandrel hangers eliminate the need to set slips and perform rough and final casing cut. Rig-up and rig-down is faster, fewer personnel are required during the process, and the period of time personnel need to work under suspended loads in confined area is minimized. Additionally, hot work during the drilling phase is...

MBD* multibowl diverter wellhead systems are time-saving two-stage wellhead systems designed specifically for offshore applications. They are ideal for shallow-gas environments and unconsolidated formations. The multibowl design enables running two casing strings in one casing head housing. The MBD system has a working pressure rating of 3,000 psi and can be used in moderate to severe service conditions. Applications ■ Offshore drilling ■ Large-bore operations Advantages ■ Compatibility with mandrel casing hangers, emergency slip-type hangers, or a combination of both ■ Availability with...

MN-DS Multibowl Nested-Diverter Snap-Ring Wellhead System Drilling The MN-DS* multibowl nested-diverter snap-ring wellhead system is specifically designed for shale plays. Its compact design is configurable to eliminate intermediate casing strings and enables the wellhead system to be run through a diverter riser, saving time and cost. The system enhances safety and well integrity because it uses internal mechanical locking rings rather than external locking mechanisms such as lockscrews, and it has no unnecessary body penetrations. Eliminating lockscrews— which are widely used in...

SOLIDrill Modular Compact Wellhead System Correctly installing the wellhead is crucial to drilling and workover operation success. But most conventional installations involve landing tubing hangers on top of the casing hanger packoff’s flat area, where debris can accumulate. This condition causes the wellhead to be misaligned, preventing proper installation and resulting in NPT. For operators conducting drilling and workovers involving complex land or deepwater wells, these challenges are accentuated. Such conditions are mitigated with the SOLIDrill* modular compact wellhead system....
