Abstract
The present invention relates to a method for inhibiting scale and corrosion in aqueous systems, for example, under high temperature and pressure conditions such as temperatures up to 250° C. and/or pressures up to 10000 psi (i.e., about 68.9 MPa). The method involves providing polymer compositions comprising 1% to 100% by weight of a phosphorus-containing amide monomer to such aqueous systems, which arise, for example, in connection with oilfield operations and some water treatment applications.
