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.
