A Newly Developed Chromium(lll) Gel Technology

Abstract

Summary: Laboratory testing of a recently developed chromium(III) [Cr(III)] gel technology is reported. The gels can be used in conjunction with a number of oilfield treatments. The single-fluid acrylamide-polymer/Cr(III)-carboxylate aqueous gels are formed by crosslinking acrylamide polymer with a Cr(III)-carboxylate-complex crosslinking agent. Representative gel compositions and associated gel properties are discussed.
