Methods of treating subterranean formations, and compositions, systems and methods for performing the methods. A method of treating a subterranean formation, including obtaining or providing a composition that includes an alkenoate ester. The composition also includes at least one of a dialkenyldihydrocarbylammonium halide and an N,Ndihydrocarbyl-substituted alkenamide. The method also includes placing the composition in a subterranean formation downhole. Methods of treating a subterranean formation using a composition including a polymer that is a reaction product of a mixture including an alkenoate ester and at least one of a dialkenyldihydrocarbylammonium halide and an N,N-dihydrocarbyl-substituted alkenamide.
1. A method of treating a subterranean formation, the method comprising:
obtaining or providing a composition comprising:
0.001 to less than 80 wt. %, based on the total weight of the composition, of an alkenoate ester having the structure
wherein R1, R2, and R3 are each independently selected from the group consisting of —H and
methyl, and wherein R4 is selected from the group consisting of methyl and ethyl; and
20 to 99.999 wt. %, based on the total weight of the composition, of an N,N-dihydrocarbyl-substituted alkenamide, having the structure
wherein R5, R6, and R7 are each independently selected from the group consisting of —H and methyl, and wherein R8 and R9 are each independently (C 10 -C 25 )alkyl;
polymerizing the alkenoate ester and the N,N-dihydrocarbyl-substituted alkenamide to form a polymer including an amide portion and a polyalkenoate portion and comprising repeating units having the structure:
wherein L 1 and L 2 are each independently a bond, a is 1 to 100,000, and b is 1 to 100,000;
mixing the polymer with a plurality of particulate substrates to provide a coated particulates; and then
placing the coated particulates in a subterranean formation downhole, and thereby contacting the subterranean formation with the coated particulates, wherein the placing of the coated particulates in the subterranean formation at least partially controls migration of downhole particulate and at least partially mitigates production of water from the formation, wherein the amide portion of the polymer provides consolidation of the downhole particulate and the polyalkenoate portion of the polymer provides mitigation of the production of water.
