Proppant comprising swellable coating thereon for treatment of subterranean formations

A method of treating a subterranean formation, comprising:

• placing a coated proppant comprising a coating into the subterranean formation, wherein the coating is swellable in contact with an aqueous medium, and wherein the coating is substantially unswollen when placed into the subterranean formation;
• and
• triggering swelling of the coating on the coated proppant within the subterranean formation by exposing the coating to the aqueous medium comprising an acidic pH, CO2, H2S, or any combination thereof;
• wherein the coating comprises a polymer comprising repeating groups having the structure:
• wherein:
• repeating groups A, B, and C have a random or block copolymer arrangement and are in the order shown or any other order,
• at each occurrence, repeating groups A, B, and C independently occur in the direction shown or in the opposite direction,
• repeating group A is about 50 mol % to about 98.999 mol % of the polymer,
• repeating group B is 1 mol % to about 50 mol % of the polymer,
• repeating group C is about 0.001 mol % to about 20 mol % of the polymer,
• A1 is selected from the group consisting of —O— and —NH—,
• R1, R2, R3, R4, and R5 are each independently selected from the group consisting of —H, halide, and substituted or unsubstituted (C1-C50)hydrocarbyl interrupted by 0, 1, 2, or 3 groups independently selected from —O—, —S—, substituted or unsubstituted —NH—, —(CH2—CH2—O)n1—, and —(CH2—CH2—CH2—O)n1—, wherein n1 is 1 to about 10,000,
• L1 is substituted or unsubstituted (C1-C50)hydrocarbylene interrupted by 0, 1, 2, or 3 groups independently selected from —O—, —S—, substituted or unsubstituted —NH—, —(CH2—CH2—O)n2—, and —(CH2—CH2—CH2—O)n2—, wherein n2 is 1 to about 10,000,
• R6, R7, R8 are each independently selected from the group consisting of —H, halide, and substituted or unsubstituted (C1-C50)hydrocarbyl interrupted by 0, 1, 2, or 3 groups independently selected from —O—, —S—, substituted or unsubstituted —NH—, —(CH2—CH2—O)n3—, and —(CH2—CH2—CH2—O)n3—, wherein n3 is 1 to about 10,000,
• L2 is selected from the group consisting of a bond and substituted or unsubstituted (C1-C50)hydrocarbylene interrupted by 0, 1, 2, or 3 groups independently selected from —O—, —S—, substituted or unsubstituted —NH—, —(CH2—CH2—O)n4—, and —(CH2—CH2—CH2—O)n4—, wherein n4 is 1 to about 10,000,
• R9 is selected from the group consisting of substituted (C1-C20)aryl and substituted or unsubstituted (C1-C20)heteroaryl,
• R10, R11 and R12 are each independently selected from the group consisting of —H, halide, and substituted or unsubstituted (C1-C50)hydrocarbyl interrupted by 0, 1, 2, or 3 groups independently selected from —O—, —S—, substituted or unsubstituted —NH—, —(CH2—CH2—O)n5—, and —(CH2—CH2—CH2—O)n5—, wherein n5 is 1 to about 10,000, and
• CLK is at least one of an intermolecular and an intramolecular crosslink comprising a substituted or unsubstituted (C1-C50)hydrocarbylene interrupted by 0, 1, 2, or 3 groups independently selected from —O—, —S—, substituted or unsubstituted —NH—, —(CH2—CH2—O)n6—, and —(CH2—CH2—CH2—O)n6—, wherein n6 is 1 to about 10,000.
