M-MC
Metal modular compact wellhead system
- Positive lockdown. The casing hanger lockdown rings are internally biased, resulting in more positive lockdown. Lockdown is assured by the proper number of turns and confirmed by tool travel.
- Time savings. The top connection of the 13 5/8-in, 15,000-psi M-MC wellhead system is the 13 5/8-in, 15,000-psi FastLock quick wellhead connector, which can be made up in approximately 20 minutes. The FastLock connector and reduced BOP connections result in typical rig-time savings of more than 50%.
- Supplemental high-strength load shoulder. The high-pressure M-MC wellhead system also features a supplemental high-strength load shoulder that enables a fullbore opening and provides the capacity to hang two long strings of casing and a 15,000-psi full blind pressure end load.
- Safety. Fewer BOP connections, wellhead penetrations (no lock screws), and through-BOP and -diverter operations reduce the exposure to potential openhole and lost-time incidents.
- Low maintenance. The reliable, field-proven design; absence of plastic packing and lock screws; and the availability of continuous control lines can significantly reduce maintenance costs.
