NON-REDUCING STABILIZATION COMPLEXANT FOR ACIDIZING COMPOSITIONS AND ASSOCIATED METHODS

摘要

Methods for reducing viscosifying tendencies of crude oil in subterranean formations using solid acid chelating agents are described. The methods include combining a solid acid chelating agent and an aqueous acid solution to form a treatment fluid, and introducing the treatment fluid into the subterranean formation. The solid acid chelating agent includes at least one aminopolycarboxylic acid functional group and at least one phosphonic acid functional group.
