Non-spherical particulates are useful in the stimulation of subterranean formations. A proppant pack composed of the non-spherical particulates exhibits greater porosity than a corresponding proppant pack composed of spherical particulates. In addition, the non-spherical particulates exhibit higher conductivity at higher stresses than spherical shaped particulates. Non-spherical particulates which are hollow and non-porous may further be at least partially filled with a chemical treatment agent including water-soluble or oil-soluble chemical treatment agents. |
