Patent number: 11059926Abstract: Copolymers having General Formula (I): in which R1 and R3 are chosen from divalent C4-C7 aliphatic groups and divalent C4-C7 heteroaliphatic groups, optionally substituted with one or more C1-C6 aliphatic groups, heteroatoms independently chosen from O, N, and S, or combinations thereof, where the divalent C4-C7 heteroaliphatic groups of R1 and R3 include one or two heteroatoms independently chosen from O, N, and S, and the maximum number of heteroatoms in R1 or R3 is two, R2 is chosen from Q1 and Q2, x is a molar fraction range chosen from 0.1 to 0.9, y is a molar fraction range chosen from 0.1 to 0.9, and z is a molar fraction range chosen from 0 to 0.8, where the summation of x, y, and z equals 1. Methods for inhibiting formation of clathrate hydrates include contacting a fluid with at least one copolymer of General Formula (I).Type: GrantFiled: December 11, 2019Date of Patent: July 13, 2021Assignees: Saudi Arabian Oil Company, King Fahd University of Petroleum & MineralsInventors: Mohamed Elanany, Abdullah Al-Malki, Manal Al-Eid, Mohammed Al-Daous, Shaikh Asrof Ali, Khalid Majnouni
