Claim 9:
10. A method for a squeeze treatment comprising:
introducing a pre-flush fluid into at least a portion of a subterranean formation improving clay stabilization, the pre-flush fluid comprising a chemical additive having the following structural formula:, , wherein the chemical additive is present in the pre-flush fluid in an amount of from about 1% to about 20% by volume of the pre-flush fluid, and wherein the chemical additive changes the rock wettability towards more water wet for enhanced scale inhibitor retention;
introducing a treatment fluid comprising a scale inhibitor into the portion of the subterranean formation after at least a portion of the pre-flush fluid has been introduced into the portion of the subterranean formation; and
introducing an after-flush fluid into the portion of the subterranean formation after at least a portion of the scale inhibitor has been introduced into the portion of the subterranean formation, the after-flush fluid comprising the chemical additive.
