ENVIRONMENTALLY FRIENDLY LOW TEMPERATURE BREAKER SYSTEMS AND RELATED METHODS

摘要

An embodiment of the present invention includes a method comprising: (a) providing a filter cake on a surface in a subterranean formation, the filter cake comprising a polymer and a bridging agent; (b) providing a filter cake clean-up fluid that comprises an aqueous fluid and L-glutamic acid ?,?-diacetic acid; and (c) contacting the filter cake with the filter cake clean-up fluid so that a portion of the subterranean formation neighboring the filter cake has a regain permeability of at least about 86%.
