Stable solutions of zirconium hydroxyalkylethylene diamine complex and use in oil field applications

摘要

A clear, stable, salt-free solution of a 1:1 molar complex of zirconium and N,N,N',N'-tetrakis-(2-hydroxypropyl)ethylene diamine. The solution can be used in a cross-linking composition comprising a cross-linkable organic polymer for oil field applications such as fluid fracturing and plugging permeable zones in subterranean formations.
