Abstract
A wellbore assembly that includes a drill string and a housing. The drill string defines a first fluid pathway extending from the drill string, through the drill bit, and out the drill bit to flow a first lost circulation material. The housing stores a second lost circulation material including at least one parameter different from the first lost circulation material. The drill string defines a second fluid pathway extending from the drill string, through the housing, and out the housing to direct, with the first fluid pathway blocked, fluid along the second fluid pathway to flow the second lost circulation material out the housing to a lost circulation zone of the wellbore. The drill string directs, with the second fluid pathway blocked, fluid along the first fluid pathway to flow the first lost circulation material out the drill bit to the lost circulation zone to plug the lost circulation zone.
