Methods of using wellbore servicing fluids comprising resilient material
View Patent ↗A method of servicing a wellbore, comprising providing a wellbore fluid comprising a carrier fluid and a resilient material, and introducing the wellbore fluid to an annulus, wherein at least a portion of the resilient material reduces in volume to affect the annular pressure.
1. A method of servicing a wellbore, comprising:
providing a wellbore fluid comprising a carrier fluid and a resilient material;
introducing the wellbore fluid to an annulus;
allowing at least a portion of the wellbore fluid to become trapped in the annulus;
placing a cement composition into the annulus; and
allowing the cement composition to set, wherein at least a portion of the resilient material reduces in volume to affect the annular pressure.
2. The method of claim 1 , wherein the resilient material comprises a natural rubber, an elastomeric material, a styrofoam bead, a graphite, a polymeric bead, or combinations thereof.
3. The method of claim 2 , wherein the natural rubber comprises rubber materials derived from a plant, latex materials derived from a plant, or combinations thereof.
4. The method of claim 2 , wherein the elastomeric material comprises a styrene-butadiene copolymer, a neoprene, a synthetic rubber, a vinyl plastisol thermoplastic, or combinations thereof.
5. The method of claim 4 , wherein the synthetic rubber comprises nitrile rubber, butyl rubber, polysulfide rubber, EPDM rubber, silicone rubber, polyurethane rubber, or combinations thereof.
6. The method of claim 1 , wherein the resilient material comprises a graphite.
7. The method of claim 1 , wherein the wellbore fluid comprises from about 1 to about 50 vol. % resilient material.
8. The method of claim 1 , wherein the carrier fluid comprises a nonaqueous-based fluid.
9. The method of claim 1 , wherein the carrier fluid comprises fresh water, salt water, brine, seawater, water-based drilling fluid, or combinations thereof.
10. The method of claim 8 , wherein the nonaqueous-based fluid comprises a diesel, crude oil, kerosene, aromatic mineral oil, non-aromatic mineral oil, linear alpha olefin, poly alpha olefin, internal or isomerized olefin, linear alpha benzene, ester, ether, linear paraffin, or combinations thereof.
11. The method of claim 1 , wherein the wellbore fluid comprises from about 10 to about 90 vol. % carrier fluid.
12. The method of claim 1 , wherein the wellbore fluid comprises a tracer, a gas-generating additive, a displacement facilitator, or combination thereof.
13. The method of claim 12 , wherein the gas-generating additive comprises azodicarbonamide, aluminum powder, or combinations thereof.
14. The method of claim 1 , wherein the at least a portion of the resilient material reduced in volume subsequently increases in volume.
15. The method of claim 14 , wherein the at least a portion of the resilient material reduced in volume increases in volume to about a normal volume of the resilient material.
16. The method of claim 14 , wherein the at least a portion of the resilient material reduced in volume increases in volume to a volume from about 70 to about 99% of a normal volume of the resilient material.
17. The method of claim 1 , wherein the wellbore fluid is a spacer fluid.
18. The method of claim 1 , further comprising introducing the wellbore fluid comprising the resilient material to the annulus with a drilling fluid.
19. The method of claim 1 , wherein at least a portion of the wellbore fluid is trapped in the annulus after the cement composition is placed into the annulus.
