Abstract
Methods of degrading filter cakes in subterranean formations are provided. An example of a method is a method of drilling a well bore in a subterranean formation. Another example of a method is a method of degrading a filter cake in a subterranean formation, the filter cake comprising an inorganic portion and an organic portion, and having been established in the formation by a well drill-in and servicing fluid that comprises a delayed-release acid component. An example of a composition is a well drill-in and servicing fluid.
