Abstract
The device for covering an opening of a wellbore includes a housing having a central opening. The housing is configured to be secured within a well center opening. Covers are arranged around the central opening and are configured to move to an open-cover position, a partially-closed-cover position, or a closed-cover position. The covers cover at least a portion of the central opening n the partially-closed cover position or the closed-cover position. An actuator extends and retract the covers. A controller sends signals to the actuator to extend and retract the covers. The controller uses motion data and diameter data of a tubular to determine the partially-closed-cover position for a cover opening time and sends signals to extend and retract the plurality of covers to the partially-closed-cover position for a cover opening time.
