摘要：
Lost circulation materials may include a plurality of self-aggregating particles having a degradable coating, wherein the self-aggregating particles are capable of bonding via mechanical interactions, electrical interactions, magnetic interactions, chemical interactions, or any combination thereof into a plurality of aggregated particles. The aggregated particles have a larger effective size and can seal large openings/apertures in the subsurface that cause lost circulation during a wellbore drilling operation.
