Abstract:
Presented herein are improved bridging agents comprising a degradable material, improved subterranean treatment fluids comprising such improved bridging agents, and methods of using such improved subterranean treatment fluids in subterranean formations. An example of a method presented is a method of drilling a well bore in a subterranean formation. Another example of a method presented is a method of forming a self-degrading filter cake in a subterranean formation. Another example of a method presented is a method of degrading a filter cake in a subterranean formation. An example of a composition of the present invention is a treatment fluid including a viscosifier, a fluid loss control additive, and a bridging agent comprising a degradable material. Another example of a composition presented is a bridging agent comprising a degradable material.
