ABSTRACT:
A water-soluble polymer and a process for using the polymer for applications in a subterranean formation are provided. The polymer comprises repeat units derived from a nitrogen-containing olefinic monomer and optionally an olefinic comonomer. The polymer can be used in drilling fluids, workover fluids, completion fluids, permeability corrections, water or gas coning prevention, fluid loss prevention, matrix acidizing, fracture acidizing, and combinations of any two or more thereof.
