Abstract: A device is provided for removing mud, fluid, and/or debris from a tubular tripping out of a wellbore. The device includes a housing configured to be secured within a well center opening. A plurality of flexible wipers are arranged around the central opening and are configured to: (a) move to an open-wiper position, a partially-closed-wiper position, or a closed-wiper position; and (b) cover at least a portion of the central opening when the plurality of wipers is in the partially-closed-wiper position or the closed-wiper position. A wiper actuator is configured to extend and retract at least two of the plurality of flexible wipers and to actuate a rotation of a drive plate. The drive plate is coupled to the plurality of flexible wipers for extending and retracting the plurality of flexible wipers.

Abstract: A device for removing mud, fluid, and/or debris from a tubular tripping out of a wellbore includes a housing having a central opening. The housing is configured to be secured within a well center opening. A plurality of flexible wipers is arranged around the central opening. The plurality of flexible wipers is configured to move to an open-wiper position, a partially-closed wiper position, or a closed-wiper position. The plurality of flexible wipers is configured to cover the central opening when the plurality of wipers is in the partially-closed-wiper position or the closed-wiper position.

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.
