Abstract

A method of treating a subterranean formation including combining an aqueous fluid, a biomaterial, an enzyme, and a deactivator to form a treatment fluid; and introducing the treatment fluid into the subterranean formation. A method is also disclosed for treating a subterranean formation by preparing a treatment fluid containing an aqueous fluid that contains bacterial and/or fungal cells that produce an enzyme that degrades the biomaterial, a biomaterial, and a deactivator; controlling degradation of the biomaterial by adding an effective amount of the deactivator to the aqueous fluid prior to the preparation of the treatment fluid; and introducing the treatment fluid into the subterranean formation. In the methods, the enzyme degrades the biomaterial and the deactivator is an oxygen-containing arene capable of inhibiting the enzyme from degrading the biomaterial.
