Abstract
A method and composition for filling voids in a subterranean formation to provide a fill having a substantially uniform permeability. A viscosified aqueous fluid is prepared to which is added a first particulate having a particle size no greater than about 10 mesh, another particulate having a particle size of less than about 1/7th the median diameter of the first particulate and a resin composition capable of coating at least a portion of the particulate. The fluid is introduced into a subterranean formation to fill at least a portion of the voids that may be present in the formation, compacted and allowed to set to provide the permeable fill material.
