ABSTRACT:
A temporary matrix is provided in treating a subterranean formation by providing a composition comprising a matrix forming material and a matrix degrading material. The matrix degrading material is capable of degrading the matrix after a period of time when subjected to existing or induced conditions of the subterranean formation. The composition is placed into a wellbore penetrating the subterranean formation. The composition is allowed to form a matrix within the wellbore, whereby the matrix at least one of significantly reduces the passage of fluid across or near the matrix or provides structural strength. A treatment operation is performed on the subterranean formation or wellbore and the degrading material is allowed to degrade the matrix.
