On-the fly coating of acid-releasing degradable material onto a particulate

A method of using a portion of a gravel pack to degrade a portion of a filter cake comprising the steps of:

• combining an acid-releasing degradable material with a solvent or a plasticizer to create a coating solution;
• wherein the acid-releasing degradable material comprises at least one acid-releasing degradable material selected from the group consisting of:
• poly(orthoester);
• a poly(ε-caprolactone);
• a poly(hydroxybutyrate);
• a substantially water insoluble anhydride;
• a poly(anhydride);
• a poly(amino acid);
• a copolymer of two or more of the above-listed compounds;
• and any combination thereof;
• coating the coating solution onto gravel on-the-fly to create coated gravel, wherein the acid-releasing degradable material comprises a material that is substantially water insoluble;
• introducing the coated gravel to a well bore having a filter cake so that at least a portion of the coated gravel is incorporated in a gravel pack substantially adjacent to the filter cake;
• allowing the acid-releasing degradable material to produce acid;
• and,
• allowing the acid to contact and degrade a portion of the filter cake.

A method of degrading filter cake in a subterranean formation comprising the steps of:

• combining an acid-releasing degradable material with a plasticizer to create a coating solution, with the proviso that the plasticizer does not comprise a starch;
• coating the coating solution onto a particulate on-the-fly to create coated particulates, wherein the acid-releasing degradable material comprises a material that is substantially water insoluble;
• placing the coated particulates into a subterranean formation so that at least a portion of the coated particulates become incorporated in a pack substantially adjacent to a filter cake;
• allowing the acid-releasing degradable material to produce acid;
• and
• allowing the acid to contact and degrade a portion of the filter cake.
