Of the many methods provided, in one embodiment, the present invention
provides a method comprising: placing a drill-in fluid in a subterranean
formation, the drill-in fluid comprising an aqueous base fluid, a
viscosifier, a relative permeability modifier fluid loss control
additive, and a degradable bridging agent comprising a degradable
material capable of undergoing an irreversible degradation downhole; and
forming a self-degrading filter cake comprising the bridging agent upon a
surface within the formation whereby fluid loss through the
self-degrading filter cake is reduced.
