US Patent 7981845 Partially neutralized polyhydroxy acids for well treatments

This relates to a method and composition for forming and utilizing a fluid in the oilfield services industry including exposing a polyacid and/or polyacid derivative to a preparation method, introducing the prepared polyacid and/or polyacid derivative to a fluid to form a treatment fluid, and treating a subterranean formation and/or a wellbore with the treatment fluid, wherein the viscosity of the treatment fluid is not observably reduced by introducing the prepared polyacid and/or polyacid derivative to a treatment fluid. This also relates to a method and composition for use in the oil field services industry including a prepared polyacid and/or polyacid derivative, a fluid, and a viscosity control agent, wherein the viscosity of the composition is not observably lower than if the prepared polyacid and/or polyacid derivative were not present.
