    摘要： Methods of forming gravel packs while reducing fluid loss to the surrounding subterranean formation. The methods involve suspending gravel that has been coated with a tackifying agent and degradable fines into a low viscosity carrier fluid and then placing that suspension into a subterranean formation so as to form a gravel pack wherein, as the gravel pack is placed, the degradable fines to de-adhere from the gravel and to fill at least a portion of the pore spaces within the gravel pack so as to reducing fluid loss through the gravel pack.

    摘要： Treatment fluids comprising degradable diverting agents and methods of using such treatment fluids in subterranean formations are provided. Examples of methods include methods of fracturing a subterranean formation. Another example of a method is a method of enhancing production from multiple regions of a subterranean formation penetrated by a well bore during a single trip through the well bore.
