  • Record HPHT Norwegian well drilled with MPD flow detection and control

    S.K. Naesheim, Frode Lefdal, Tor Øyvind Oftedal and Henrik Sveinall

    The Mandarin East well exhibited the most extreme temperature and pressure ever encountered while drilling a Norwegian well. Planning for this exploratory well had anticipated a surface pressure of nearly 15,000 psi and extremely high temperatures. To understand and control wellbore dynamics while maintaining an overbalanced wellbore, operator BG Norge installed a managed pressure drilling (MPD) system to provide early kick detection and allow for wellbore breathing mitigation.
