Claim:
1. A subterranean well treatment system for a subterranean well, the subterranean well comprising a plurality of flow channels within a petroleum bearing formation, the petroleum bearing formation having specific characteristics, wherein at least one of the flow channels is impaired, and wherein said system treats the subterranean well by alleviating the impairment, said system comprising: a liquid treatment agent comprising a solvent and a surfactant solution that comprises a plurality of different non-ionic ethoxylated sorbitan fatty acid ester surfactants compounded together that achieve a hydrophilic-lipophilic balance which matches the specific characteristics of the petroleum bearing formation; a source of a carrier gas to supply a continuous flow of said carrier gas into the subterranean well to push any liquids out of the plurality of flow channels; and an atomizer that atomizes said liquid treatment agent into said carrier gas to create an atomized non-foaming treatment fog comprising said atomized liquid treatment agent blended with said carrier gas in a concentration sufficient to suspend said atomized liquid treatment agent as a fog within said carrier gas.
