From the 2012 ATCE exhibit floor: Closed-loop drilling mitigates well control events

Brian Grayson, Weatherford global manager of emerging technologies for drilling optimization services, speaks with Drilling Contractor editorial coordinator Katherine Scott at the 2012 SPE Annual Technical Conference & Exhibition, 8-10 October in San Antonio, Texas, about how not using closed-loop drilling is like driving with your car lights off, about the principle of mass balance and how an operation is 470 times less likely to experience a blowout by using closed-loop drilling.
