Automated system provides well control for extreme drilling environments, enhances MPD

摘要

THE ESSENCE OF wen control is information. Ideally, downhole information facilitates a knowledgeable, expert response to prevent a costly or even catastrophic well control event. But in reality, good and timely information have been difficult to acquire and apply - especially in the extremes of modern wellborcs where it is needed most. That is changing quickly. By integrating a closed-loop drilling system with real-time monitoring and automated well control capabilities, some of the world's most difficult well control conditions are being routinely drilled - from total circulation losses in "undrillable" carbonates to threading narrow drilling windows in deepwater boreholes.
