HYDRAULIC DIVERSION SYSTEMS TO ENHANCE MATRIX TREATMENTS AND METHODS FOR USING SAME
Systems and methods for treating formation intervals including forming a low permeability layer on a surface of the interval and pumping a sand control treating solution through the layer, which diverts the flow into the formation permitting improved treatment uniformity and improved overall internal treatment.
A borehole completion method treats a formation surrounding a borehole with a chemical treatment that alters how formation particulates interact. A standalone screen deploys downhole in the borehole (either before or after the treatment) on a downhole string. When fluid is produced, formation particulates treated with the chemical treatment agglomerate in the annulus surrounding the screen in permeable structures. This can be especially when the standalone screen is useful in a cased hole having perforations. The chemical treatment includes an inner salt adapted to neutralize the zeta potential (i.e., electrokinetic potential) of the formation particulates so they aggregate into one or more permeable structures in the annulus.
