What is claimed is: 1. A method of installing a gravel pack in a well bore comprising the steps of: providing resin coated particulates wherein the resin comprises a resin that does not completely cure unless it is at least one of: exposed to a temperature above about 175째 F. or exposed to an external catalyst; providing a gravel packing fluid; substantially slurrying the resin coated particulates in the gravel packing fluid to create a resin coated particulate slurry wherein the slurry is capable of being stored for at least 2 hours before use; introducing the resin coated particulate mixture to the well bore such that the resin coated particulates form a gravel pack substantially adjacent to the well bore; and, allowing the resin coated particulates to substantially cure. 2. The method of claim 1 wherein the high temperature curable resin is selected from the group consisting of a furan-based resin, a phenolic-based resin, a high-temperature (HT) epoxy-based resin, a phenol/phenol formaldehyde/furfuryl alcohol resin, and a combination thereof. 3. The method of claim 1 wherein the high temperature curable resin further is selected from the group consisting of a hydrolyzable ester, a silane coupling agent, a surfactant, and a combination thereof. 4. The method of claim 1 where in the external catalyst is selected from the group consisting of hydrochloric acid, phosphoric acid, acetic acid, fumaric acid, sulfonic acid, and combinations thereof. 5. The method of claim 1 wherein the gravel packing fluid is selected from the group consisting of an aqueous gel, a foam, an emulsion, a crosslinked viscosified fluid, and a combination thereof. 6. The method of claim 1 wherein the high temperature curable resin is coated onto the particulates on-the-fly. 7. The method of claim 1 wherein the well bore exhibits a temperature at above about 175째 F. 8. The method of claim 1 wherein the subterranean formation exhibits a temperature of below about 175째 F. and further comprising, after the step of introducing the resin coated particulate slurry to the well bore such that the resin coated particulates form a gravel pack substantially adjacent to the well bore, the step of placing an after-flush solution comprising an external catalyst into the well bore. 9. The method of claim 1 wherein the gravel packing fluid has an apparent viscosity (at a shear rate of 1) from about 40,000 cp to about 200,000 cp; a maxwellian stress relaxation of from about 1 to about 3 minutes; and a maxwellian equilibrium limit from about 0.035 to about 0. 1. 10. A method of installing a gravel pack in a well bore comprising the steps of: providing tackifier coated particulates; providing a gravel packing fluid; substantially slurrying the tackifier coated particulates in the gravel packing fluid to create a tackifier coated particulate slurry wherein the slurry is capable of being stored for at least 2 hours before use; and, introducing the tackifier coated particulate slurry to the well bore such that the tackifier coated particulates form a gravel pack substantially adjacent to the well bore. 11. The method of claim 10 wherein the tackifier is selected from the group consisting of a polyamide, a polyester, a polycarbonate, polycarbamate, a natural resin, and a combination thereof. 12. The method of claim 10 wherein the gravel packing fluid is selected from the group consisting of an aqueous gel, a foam, an emulsion, a crosslinked viscosified fluid, and a combination thereof. 13. The method of claim 10 wherein the tackifier is coated onto the particulates on-the-fly. 14. The method of claim 10 further comprising the step of: combining the tackifier coated particulates with a multifunctional material before the step of: substantially suspending the tackifier coated particulates in a servicing fluid to create a tackifier coated particulate slurry wherein the slurry is capable of being stored for at least 2 hours before use. 15. The method of claim 10 wherein the multifunctional material is selected from the group consisting of an aldehyde; a dialdehyde; a hemiacetal; an aldehyde releasing compound; a diacid halide; a dihalide; a polyacid anhydride; an epoxide; furfuraldehyde, glutaraldehyde or aldehyde condensates; and combinations thereof. 16. The method of claim 10 wherein the gravel packing fluid has an apparent viscosity (at a shear rate of 1) from about 40,000 cp to about 200,000 cp; a maxwellian stress relaxation of from about 1 to about 3 minutes; and a maxwellian equilibrium limit from about 0.035 to about 0. 1.
