Hydrophobically modified amine-containing polymers (“HMAP”) may be useful in mitigating scale buildup in a subterranean formation. For example, a method may include preparing a treatment fluid that comprises a base fluid and a plurality of HMAP-coated particulates that comprise particulates at least partially coated with an HMAP, wherein the HMAP comprises a plurality of hydrophobic modifications on an amine-containing polymer; introducing the treatment fluid into a wellbore penetrating a subterranean formation; forming a particulate pack that comprises at least some of the HMAP-coated particulates; and inhibiting scale buildup on the HMAP-coated particulates.

1. A method comprising: preparing a treatment fluid that comprises a base fluid and a plurality of hydrophobically modified amine-containing polymer (HMAP) coated particulates that comprise particulates at least partially coated with an HMAP, wherein the HMAP comprises a plurality of hydrophobic modifications on a poly(vinyl imidazole);introducing the treatment fluid into a wellbore penetrating a subterranean formation;forming a particulate pack that comprises at least some of the HMAP-coated particulates; andinhibiting scale buildup on the HMAP-coated particulates. 2. The method of claim 1, wherein the hydrophobic modification comprises a C4-C30 characterized by at least one selected from the group consisting of a straight chain, a branched chain, comprising an unsaturated C—C bond, comprising an aryl group, and any combination thereof. 3. The method of claim 1, wherein the particulate comprises at least one selected from the group consisting of a proppant, a gravel particulate, and any combination thereof. 4. The method of claim 1, wherein the HMAP-coated particulates further comprise a coupling agent. 5. The method of claim 1, wherein the HMAP-coated particulates are present in an amount ranging from about 0.1 pounds per gallon to about 30 pounds per gallon of the treatment fluid. 6. The method of claim 1 further comprising: forming the HMAP-coated particulates by dry-coating the particulates with the HMAP; andadding the HMAP-coated particulates to the treatment fluid. 7. The method of claim 1, wherein preparing the treatment fluid involves adding HMAP to a mixture of the base fluid and the particulates. 8. The method of claim 1, wherein preparing the treatment fluid involves adding the particulates to a mixture of the base fluid and the HMAP. 9. The method of claim 1 further comprising: introducing a pad fluid into the subterranean formation at a pressure sufficient to create or extend at least one fracture in the subterranean formation before introducing the treatment fluid. 10. A method comprising: providing a treatment fluid that comprises a base fluid and a hydrophobically modified amine-containing polymer (HMAP), the HMAP comprising a plurality of hydrophobic modifications on a poly(vinyl imidazole);introducing the treatment fluid into a wellbore penetrating a subterranean formation, wherein a portion of the wellbore, a portion of the subterranean formation, or both comprise a plurality of particulates;coating at least some of the particulates with HMAP, thereby forming HMAP-coated particulates; andinhibiting scale buildup on the HMAP-coated particulates. 11. The method of claim 10, wherein the hydrophobic modification comprises a C4-C30 characterized by at least one selected from the group consisting of a straight chain, a branched chain, comprising an unsaturated C—C bond, comprising an aryl group, and any combination thereof. 12. The method of claim 10, wherein the particulates comprise at least one selected from the group consisting of formation fines, formation sand, a proppant, a gravel particulate, and any combination thereof. 13. The method of claim 10, wherein the HMAP is present in an amount ranging from about 0.01% to about 3% by weight of the base fluid. 14. The method of claim 10, wherein the treatment fluid further comprises a coupling agent in an amount ranging from about 0.001% to about 3% by weight of the HMAP. 15. The method of claim 10 further comprising: forming a proppant pack in the portion of the wellbore, the portion of the subterranean formation, or both before introducing the treatment fluid. 16. The method of claim 10 further comprising: forming a gravel pack in the portion of the wellbore, the portion of the subterranean formation, or both before introducing the treatment fluid. 17. The method of claim 10 further comprising introducing an acidizing fluid into the subterranean formation before introducing the treatment fluid. 18. A system comprising: a wellhead with a tubular extending therefrom and into a wellbore in a subterranean formation; anda pump fluidly coupled to a tubular, the tubular containing a treatment fluid that comprises a base fluid and a plurality of hydrophobically modified amine-containing polymer (HMAP) coated particulates, wherein the HMAP comprises a plurality of hydrophobic modifications on a poly(vinyl imidazole).
