With the growth of a fleet of CLD-ready rigs, deepwater drilling operations are poised to benefit from advantages based on closed-loop systems. Closed-loop drilling (CLD) systems are the foundation for the evolution of floating rigs able to effectively address the challenges of ever-deeper drilling horizons. A CLD system enables drilling modifications in three key segments: riser gas handling; reactive early kick detection, which is an adjunct to riser gas handling achieved with die addition of mass-flow measurement; and a proactive suite of managed-pressure drilling (MPD) methodologies that are bringing nontraditional solutions to complex deepwater drilling challenges.
