Claims
- 1. A method for forming a gravel pack in a wellbore penetrating a subterranean formation, said method comprising the steps of:
creating a gravel pack mixture using a solid deformable material and a conventional gravel; and placing such gravel pack mixture in said wellbore.
- 2. The method of claim 1 wherein the gravel pack contains from 10% to 50% by weight of solid deformable material and from 50% to 90% by weight of conventional gravel.
- 3. The method of claim 2 wherein the solid deformable material is an elastically flexible or plastically compressible material.
- 4. The method of claim 3 wherein the gravel pack contains from 15% to 30% by weight of solid deformable material and from 70% to 85% by weight of conventional gravel.
- 5. The method of claim 3 wherein the solid deformable material is a solid or foamed polymer.
- 6. The method of claim 4 wherein the gravel pack contains 20% by weight of solid deformable material and 80% by weight of conventional gravel.
- 7. The method of claim 3 wherein the solid deformable material is in the form of a particle of a substantially non-deformable material coated with an elastically flexible or plastically compressible material.
- 8. The method of claim 3 wherein the solid deformable material is in the form of a particle of an elastically flexible or plastically compressible material containing a substantially non-deformable filler.
- 9. The method of claim 3 wherein the overall compressive stiffness of the gravel pack containing solid deformable material and conventional gravel is 33% to 67% of the stiffness of a gravel pack containing the conventional gravel alone.
- 10. The method of claim 3 wherein the overall compressive stiffness of the gravel pack containing solid deformable material and conventional gravel is 33% to 50% of the stiffness of a gravel pack containing the conventional gravel alone.
- 11. The method of claim 1 wherein the gravel pack contains from 10% to 50% by volume of solid deformable material and from 50% to 90% by volume of conventional gravel.
- 12. The method of claim 11 wherein the solid deformable material is an elastically flexible or plastically compressible material.
- 13. The method of claim 12 wherein the gravel pack contains from 15% to 30% by volume of solid deformable material and from 70% to 85% by volume of conventional gravel.
- 14. The method of claim 12 wherein the solid deformable material is a solid or foamed polymer.
- 15. The method of claim 13 wherein the gravel pack contains 20% by volume of solid deformable material and 80% by volume of conventional gravel.
- 16. The method of claim 12 wherein the solid deformable material is in the form of a particle of a substantially non-deformable material coated with an elastically flexible or plastically compressible material.
- 17. The method of claim 12 wherein the solid deformable material is in the form of a particle of an elastically flexible or plastically compressible material containing a substantially non-deformable filler.
- 18. A gravel pack for a wellbore penetrating a subterranean formation, said gravel pack containing a mixture of a solid deformable material and a conventional gravel.
- 19. The gravel pack of claim 18 wherein the gravel pack contains from 10% to 50% by weight of solid deformable material and from 50% to 90% by weight of conventional gravel.
- 20. The gravel pack of claim 18 wherein the gravel pack contains from 15% to 30% by weight of solid deformable material and from 70% to 85% by weight of conventional gravel.
