Cameron was the first to engineer surface wellhead systems rated to 30,000 psi and 450 degF and qualified per Api 6A Appendix F. Drilling dRiLLiNG | 7The 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� iC Conventional Wellhead System Applications ■ Offshore and onshore drilling and production Advantages ■ Straight-bore design with a 45 load shoulder ■ Working pressure up to 10,000 psi [68�9 MPa] excluding tubing stool ■ Operating temperatures from –20 to 150 degF [–29 to 65 degC] ■ Hangoff capacity up to 50 of pipe body yield ■ Casing head housings and spools IC-2, IC-2-BP, and IC-2-L ■ Casing hangers IC-1, IC-1P, and IC-2 slip and seal assemblies ■ Optional secondary seals and packoff bushings ■ Interchangeability ■ Compatibility with many configurations The IC wellhead system uses a straight-bore design with a 45 load shoulder. 8 | SURFACE SYSTEMS TECHNOLOGY | dRiLLiNGThe 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 per 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 not required� drill-Through Wellhead System Applications ■ Shale drilling ■ Onshore drilling and production Benefits ■ Eliminated need for hot work during drilling ■ Reduced required BOP connections ■ Fewer personnel required during process ■ Minimized time spent working under suspended loads in a confined area ■ Expedited rig-up and rig-down Features ■ Casing head landing joint that is tailored to specific rig kelly bushing to ensure proper elevation of cementing head on rig floor ■ No requirement for B-section spool when drilling out for liner casing, saving an estimated 8–12 h ■ Hanger design with integral flutes that enable cement returns to pass up through the BOP stack ■ Packoff and bit guide that are run through the BOP stack, locked in place, and tested ■ Positively locked-in-place packoff during tubing head installation ■ Left-hand Acme thread for quick makeup and assurance of proper backout and removal of mandrel hanger running tool dRiLL-THROUGH WELLHEAd SYSTEM | 9 DrillingMBD* 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 ations� 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� MBd Multibowl diverter Wellhead System Applications ■ Offshore drilling ■ Large-bore operations Advantages ■ Compatibility with mandrel casing hangers, emergency slip-type hangers, or a combination of both ■ Availability with butt-weld connectors and SlipLock* wellhead connectors and 4-in line pipe outlets for cement return ■ Positive sealing and testing of casing strings hung in the casing head before disconnection of diverter ■ Full range of completion possibilities, including MBS* multibowl and IC conventional wellhead systems ■ Ability to run two strings of casing through the diverter, saving a rig-up and rig-down cycle 10 | SURFACE SYSTEMS TECHNOLOGY | dRiLLiNGThe 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 conventional wellheadssignificantly reduces potential leak paths and facilitates any wellhead intervention under the BOPs that may be required during drilling� MN-dS Multibowl Nested-diverter Snap-Ring Wellhead System Applications ■ Shale drilling ■ Onshore drilling and production Advantages ■ Spin-on flange design that enables running wellhead through a diverter riser ■ Internal lockdown hangers that eliminate penetrations from lockscrews in the housing ■ Production casing hanger that can be plugged using either a threaded or latch-type backpressure valve BPV ■ Individual contained annulars sealed using a retrievable packoff that enable the use of fluted mandrel hangers and the ability to replace casing hanger seals if necessary ■ Robust studded configuration of both upper and lower housing outlets ■ Option to complete as a one-stage system if intermediate casing is not required ■ Reduced cost of inventory with common internal components and running tools used in both 5,000- and 10,000-psi systems MN-dS MULTiBOWL NESTEd-divERTER SNAp-RiNG WELLHEAd SYSTEM | 11 DrillingCorrectly 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� Available in either two-or three-stage arrangements with 11-in and 13⅝-in nominal sizes, the SOLIDrill system has a compact, unitized housing and provides operational flexibility in a single system� The system is designed to endure extreme operating conditions, pressures up to 10,000 psi, and severe kickoff well angles up to 60 kickoff at 80 m while increasing safety and efficiency� Its proprietary design reduces the possibility of hanger tilt and secures reliable hanger alignment while reducing wellhead debris� SOLidrill Modular Compact Wellhead System Applications ■ Onshore and offshore drilling and production Advantages ■ Accommodation of different casing programs and a wide range of tubing programs, including single tubing, dual tubing, and completions with ESP cable penetrator, from a single system and with minimal tooling ■ Self-aligning hanger and centralizing features ■ Optional temporary lockdown when landing casing hangers to facilitate cementing ■ Debris-tolerant design with proprietary profiles and features ■ Optional feedback capability on housing misalignment ■ Position indication for assurance of correct landoff and installation ■ Reduced maintenance costs and exposure to potential openhole and lost-time incidents with reduced number of BOP connections, wellhead penetrations no lockscrews, and through-BOP and -diverter operations ■ Design with quick connectors and diverter connections and reduced BOP connections, resulting in rig-time savings of up to 50 12 | SURFACE SYSTEMS TECHNOLOGY | dRiLLiNGCSW* conductor-sharing wellhead systems enable drilling of up to three dual-completion wells from a single slot, saving up to 20 on individual well costs and reducing plat size� The CSW system is available in 9-in, 11-in, and 13⅝-in nominal sizes and working pressures to 10,000 psi� It is suitable for moderate to severe working environments� CSW Conductor-Sharing Wellhead System Applications ■ Offshore drilling and production Advantages ■ No commitment requirement for second or third
