Abstract
Completion fluid compositions designed for fluid loss control in a subterranean formation. In particular, the compositions comprise an aqueous base fluid, a suspension polymer, a fluid loss control additive, and a degradable bridging agent. The completion fluid compositions provide a way to temporarily seal a wellbore communicating with a subterranean formation and enables completion or workover operations to be performed, after which the composition can be removed by contact with a mild clean-up composition.
