Abstract
Methods of acidizing subterranean formations using solid acids are described. The methods include providing a treatment fluid containing a solid acid chelating agent 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. The treatment fluid is substantially free of an additional acid or acid-generating compound.
