What is claimed is: 1. A method of degrading filter cake in a subterranean formation comprising the steps of: providing a particulates coated with an acid-releasing degradable material; placing the particulates into a subterranean formation so that they form 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. 2. The method of claim 1 wherein the filter cake is a filter cake on the walls of a well bore or a filter cake on the walls of a fracture. 3. The method of claim 1 wherein the particulates are coated with from about 0.1% to about 20% acid-releasing degradable material by weight of the particulates. 4. The method of claim 1 wherein the acid-releasing degradable material comprises a material that is substantially water insoluble and that degrades over time in an aqueous environment. 5. The method of claim 1 wherein the acid-releasing degradable material is chosen from the group consisting of substantially water insoluble esters, orthoesters, poly(orthoesters), aliphatic polyesters, lactides, poly(lactides), glycolides, poly(glycolides), poly(ε-caprolactones), poly(hydroxybutyrates), substantially water insoluble anhydrides, poly(anhydrides), aliphatic carbonates, polycarbonates, poly(amino acids), polyphosphazenes, and combinations thereof. 6. The method of claim 1 wherein the acid-releasing degradable material further comprises a solvent. 7. The method of claim 6 wherein the solvent is chosen from the group consisting of acetone, propylene carbonate, dipropylglycolmethylether, methylene chloride, isopropyl alcohol, and combinations thereof. 8. A method of using a portion of a gravel pack to degrade a portion of a filter cake comprising the steps of providing a gravel pack composition comprising gravel particles coated with an acid-releasing degradable material; introducing the gravel pack composition to a well bore having a filter cake so that the gravel pack composition forms 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. 9. The method of claim 8 wherein the gravel pack compositions comprises from about 0.1% to about 20% acid-releasing degradable material by weight of the gravel particles. 10. The method of claim 8 wherein the acid-releasing degradable material comprises a material that is substantially water insoluble such that it degrades over time. 11. The method of claim 8 wherein the acid-releasing degradable material is chosen from the group consisting of substantially water insoluble esters, orthoester, poly(orthoesters), aliphatic polyesters, lactides, poly(lactides), glycolides, poly(glycolides), poly(ε-caprolactones), polv(hydroxybutyrates), substantially water insoluble anhydrides, poly(anhydrides), aliphatic carbonates, polycarbonates, poly(amino acids), polyphosphazenes, and combinations thereof. 12. The method of claim 8 wherein the acid-releasing degradable material further comprises a solvent. 13. The method of claim 12 wherein the solvent is chosen from the group consisting of acetone, propylene carbonate, dipropylglycolmethylether, methylene chloride, isopropyl alcohol, and combinations thereof. 14. A method of using a portion of a proppant pack to degrade filter cake comprising the steps of: providing a proppant pack composition comprising proppant particles coated with an acid-releasing degradable material; introducing the proppant pack composition to a fracture so that a proppant pack forms against walls of the fracture wherein a wall of the fracture has a filter cake thereon; allowing the acid-releasing degradable material to produce acid; and, allowing the acid to contact and degrade a portion of the filter cake. 15. The method of claim 14 wherein the proppant pack composition comprises from about 0.1% to about 20% acid-releasing degradable material by weight of the gravel particles. 16. The method of claim 14 wherein the acid-releasing degradable material comprises a material that is substantially water insoluble such that it degrades over time. 17. The method of claim 14 wherein the acid-releasing degradable material is chosen from the group consisting of substantially water insoluble esters, orthoesters, poly(orthoesters), aliphatic polyesters, lactides, poly(lactides), glycolides, poly(glycolides), poly(ε-caprolactones), poly(hydroxybutyrates), substantially water insoluble anhydrides, poly(anhydrides), aliphatic carbonates, polycarbonates, poly(amino acids), polyphosphazenes, and combinations thereof. 18. The method of claim 14 wherein the acid-releasing degradable material further comprises a solvent. 19. The method of claim 18 wherein the solvent is chosen from the group consisting of acetone, propylene carbonate, dipropylglycolmethylether, methylene chloride, isopropyl alcohol, and combinations thereof.
