Wellbore servicing compositions and methods of making and using same

1. A method of servicing a wellbore comprising;

identifying a lost circulation zone within a wellbore; and

placing in the wellbore a composition comprising a wax and a water-based mud wherein placement of the composition reduces or prevents a loss of fluids to the lost circulation zone and wherein the wax has a needle penetration at 77° F. of equal to or less than about 5 mm.

2. The method of claim 1 wherein the wax comprises a natural wax, a synthetic wax, or combinations thereof.

3. The method of claim 1 wherein the wax has a melting point of from about 190° F. to about 500° F.

4. The method of claim 1 wherein the wax is an oxidized wax.

5. The method of claim 1 wherein the wax is an oxidized polyethylene wax, a blend of oxidized polyethylene waxes, an oxidized polypropylene wax, a blend of oxidized polypropylene waxes or combinations thereof.

6. The method of claim 1 wherein the wax has a saponification number of from about 0 to about 150 mg KOH/g.

7. The method of claim 1 wherein the wax has an acid number of from about 0 to about 60 mg KOH/g.

8. The method of claim 1 wherein the wax has an oil swellability of less than about 50% by volume.

9. The method of claim 1 wherein the wax has a softening point of greater than about 200° F.

10. The method of claim 1 wherein the wax is present in the composition in an amount of from about 5 lb/bbl to about 50 lb/bbl.

11. The method of claim 1 wherein the composition further comprises a bridging agent.

12. The method of claim 11 wherein the bridging agent comprises a sized calcium carbonate.

13. The method of claim 11 wherein the bridging agent is present in the composition in an amount of from about 0 to about 90 lb/bbl.

14. The method of claim 1 further comprising introducing to the wellbore an oleaginous fluid wherein the wax is soluble in the oleaginous fluid.

15. The method of claim 1 wherein the wax has a needle penetration at 77° F. of equal to or less than about 3 mm.
