  • Compositions and methods including formate brines for conformance control
    Patent number: 6838417
    Abstract: Compositions and methods are provided for reducing the permeability of subterranean zones. More particularly, water-soluble polymeric compositions which form cross-linked gels in the zones. In general, the composition comprises (a) at least one water-soluble polymer; (b) at least one organic gelling agent capable of cross-linking the water-soluble polymer; and (c) at least one water-soluble formate. More preferably, the water-soluble polymer is a copolymer of (i) at least one non-acidic ethylenically unsaturated polar monomer, and (ii) at least one copolymerisable ethylenically unsaturated ester. The gelling agent is preferably selected from the group consisting of a polyalkyleneimine, polyfunctional aliphatic amine, an aralkylamine, and a heteroaralkylamine. The preferred water-soluble formate is selected from the group consisting of ammonium formate, lithium formate, sodium formate, potassium formate, rubidium formate, cesium formate, and francium formate.
