Abstract
Systems and methods for treating formation intervals including forming a low permeability layer on a surface of the interval and pumping a treating fluid, where the treatment fluid is diverted through the layer permitting improved treatment uniformity across the formation or intervaland permitting a longer interval to be treated, where the layer comprises self-degradable material that degrade over time without harm to the formation or interval surfaces.
