摘要

A high pressure, high temperature (HPHT) fluid loss additive and, in particular, a fluid loss additive for oil-field drilling applications is described. In accordance with one aspect, the fluid loss additive comprises a terpolymer of acrylamide (AM), 2-acrylamido-2-methyl-propanesulfonic acid (AMPS) and a cationic monomer such as acrylamidopropyl-trimethyl ammonium chloride (APT AC) and/or methacrylamidopropyltrimethyl ammonium chloride (MAPTAC).
