Abstract:
The flow of a stimulation fluid may be diverted from a high permeability zone to a low permeability portion of a subterranean formation by use of an acid soluble or acid degradable solid particulate and a composite of an acid or an acid generating compound adsorbed onto a water-insoluble adsorbent. Conductive flow of hydrocarbons from an occluded fracture may be resumed by release of the acid from the adsorbent or the acid generating compound.

Claim (Index 19):
A method of stimulating a subterranean formation penetrated by a well comprising:\n (a) pumping into the well and into the subterranean formation (i) an acid soluble or acid degradable solid particulate and (ii) a composite comprising an acid adsorbed onto a water-insoluble adsorbent or an acid generating compound adsorbed onto a water-insoluble adsorbent; (b) blocking at least a portion of the subterranean formation with the acid soluble or acid degradable solid particulate; (c) pumping a stimulation fluid into the well; (d) diverting the flow of the stimulation fluid from the blocked portion of the subterranean formation to another portion of the formation, wherein the permeability of the subterranean formation blocked by the acid soluble or acid degradable solid particulate is greater than the permeability of the another portion of the formation; and (e) solubilizing or degrading the solid particulate blocking at least a portion of the subterranean formation by releasing or generating acid from the water-insoluble adsorbent.
