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.
