Abstract
Systems and methods deliver degradable polyester during gravel packing and may include a gravel pack system disposed within a wellbore formed in a subterranean formation. The systems and methods may include drilling at least one interval of a wellbore with a non-aqueous wellbore fluid, wherein the non-aqueous wellbore fluid produces a filter cake in the at least one interval of the wellbore and gravel packing an interval of a wellbore traversing a subterranean formation with a gravel pack that comprises non-aqueous gravel pack carrier fluid and proppants. The systems and methods may also include hydrolyzing degradable polyester that is associated with the gravel pack and degrading at least one portion of the filter cake.
Claims (20)
1. A method comprising: drilling at least one interval of a wellbore with a non-aqueous wellbore fluid, wherein the non-aqueous wellbore fluid produces a filter cake in the at least one interval of the wellbore; gravel packing an interval of a wellbore traversing a subterranean formation with a gravel pack that comprises non-aqueous gravel pack carrier fluid and proppants; and hydrolyzing degradable polyester that is associated with the gravel pack; and degrading at least one portion of the filter cake.
2. The method of claim 1 , further comprising: introducing a filter cake breaker fluid system into the interval of the wellbore traversing the subterranean formation, wherein the filter cake breaker fluid system comprises the degradable polyester.
3. The method of claim 1 , further comprising: adding sized degradable polyester particles to the gravel pack prior to the interval of the wellbore traversing the subterranean formation being gravel packed, wherein the sized degradable polyester particles comprise the degradable polyester.
4. The method of claim 1, wherein at least a portion of the proppants is infused or coated with the degradable polyester.
5. The method of claim 1 , wherein the non-aqueous gravel pack carrier fluid is a reversible invert emulsion fluid.
6. The method of claim 1 , wherein an organic acid releasable from the degradable polyester hydrolyzes and decreases the pH of the gravel pack to a pH value that is less than about 5.
7. The method of claim 1 , wherein an organic acid releasable from the degradable polyester comprises at least one acid selected from polylactic acid, polyglycolic acid, polylactic-co-glycolicacid, polymalicacid, polygluconicacid, poly citric acid, poly mandelic acid, polysaccharide acid, poly mucic acid, and poly tartaric acid.
8. The method of claim 1, wherein the organic acid comprises polylactic acid or polylactic-co-glycolic acid.
9. The method of claim 1 , further comprising: reverting the non-aqueous gravel pack carrier fluid to a water-wet state prior to the at least one portion of the filter cake being degraded.
10. The method of claim 1 , further comprising: decreasing the pH of the gravel pack to a lower pH value to revert the non-aqueous gravel pack carrier fluid to the water-wet state, wherein the lower pH value is less than about 5.
11. A method comprising: running a sand control screen assembly to a selected depth within the uncased section of the wellbore to facilitate a gravel packing operation; and introducing a gravel pack slurry comprising non-aqueous gravel pack carrier fluid and degradable polyester into the wellbore to facilitate gravel packing operations.
12. The method of claim 11 , wherein the degradable polyester is in the form of sized degradable polyester particles.
13. The method of claim 11, wherein the gravel pack slurry further comprises proppants and the degradable polyester is infused into or coated onto at least a portion of the proppants.
14. The method of claim 11, wherein the non-aqueous gravel pack carrier fluid is a reversible invert emulsion fluid.
15. The method of claim 11 , further comprising: decreasing the pH of the gravel pack slurry to a lower pH value to revert the non- aqueous gravel pack carrier fluid to a water-wet state, wherein the lower pH value is less than about 5, less than about 4, less than about 3, or between about 2 and about 3.
16. The method of claim 11, wherein an organic acid releasable from the degradable polyester comprises at least one acid selected from polylactic acid, polyglycolic acid, polylactic-co-glycolicacid, polymalicacid, polygluconicacid, poly citric acid, poly mandelic acid, polysaccharide acid, poly mucic acid, and poly tartaric acid.
17. The method of claim 11, wherein the organic acid of the degradable polyester hydrolyzes and decreases the pH of the gravel pack to a pH value ranging from about 1 to about 5.
18. The method of claim 11 , further comprising: introducing a filter cake breaker fluid system into the wellbore; and degrading at least one portion of a filter cake disposed within the wellbore.
19. A gravel pack system configured for gravel packing an interval of a wellbore traversing a subterranean formation, the gravel pack system comprising: a reversible invert emulsion gravel pack carrier fluid comprising an alkaline agent, an amine as a primary emulsifier, and a tail-oil fatty acid as a secondary emulsifier; a plurality of proppants; and degradable polyester.
20. The gravel pack system of claim 19, wherein the degradable polyester is in the form of sized degradable polyester particles or are infused within or coated onto at least one proppant of the plurality of proppants.
