A copolymer useful as a water clarifier for a water phase of a production fluid is selected from those with a first monomer and a second monomer, and in one non-limiting embodiment having the general formula: n n n n n n n n n n wherein y is 10 to 50,000; z is 1 to 10,000 and n is 1 to 250. The copolymer may optionally include a third monomer. In an optional embodiment of the process, the fluid has a hydrocarbon phase, and the process further involves simultaneously drying the hydrocarbon phase of the fluid along with clarifying the water phase. |
