IPC MPD

Vertechs IPC MPD system is an all-electric managed pressure drilling solution that integrates iChoke (Intelligent All-Electric MPD Choke) and the IPC MPD - Auto Control System, designed to deliver a rapid and stable response to pressure fluctuations during complex and variable drilling conditions. Compared with conventional hydraulic-actuated MPD configurations, the compact all-electric iChoke architecture can largely reduce equipment footprint and hydraulic-system complexity.
