ABSTRACT:
Methods are provided for treating an underground well formation whereby the treatment is confined to a desired zone within the formation. The methods comprise introducing one or more preflush fluids into one or more fractures in the formation followed by the introduction of a treating fluid having a density differing sufficiently from the density of the preflush fluids whereby the treating fluid is segregated and caused to flow into a desired zone within the formation.
