A copolymer useful as a water clarifier for an aqueous phase of a production fluid is selected from those with a first monomer and a second monomer and, in a non-limiting embodiment, has the general formula: (see Formula) where y is of 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, together with the clarification of the aqueous phase. |
