Abstract: Novel completion fluid compositions for fluid loss control during completion conducted on a wellbore penetrating a subterranean formation are disclosed. In particular, the composition described herein has an aqueous base fluid, a suspension polymer, a fluid loss control additive, and a degradable bridging agent. These novel compositions provide a means to temporarily seal a wellbore communicating with a subterranean formation to enable completion or workover operations to be performed, after which the composition can be removed by contact with a mild clean-up composition.
