Abstract

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. 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.

Claims (9)

1. A method of stimulating production of hydrocarbons from a subterranean formation penetrated by a wellbore, comprising introducing into the wellbore proppants of hollow, non-spherical particulates, and forming a proppant pack of the proppants in the formation, wherein the proppant pack exhibits greater conductivity at closure stresses greater than about 1500 psi at a temperature greater than 150° F. than a corresponding proppant pack composed of spherical particulates of equivalent bulk volume.

2. The method of claim 1 , wherein the hollow, non-spherical particulates are porous.

3. The method of claim 1 , wherein hollow, non-spherical particulates are non-porous.

4. The method of claim 1 , wherein the porosity of the proppant pack is between from about 45 to about 70 percent.

5. The method of claim 1 , wherein the hollow, non-spherical particulates are at least partially filled with a water-soluble or oil-soluble chemical treatment agent.

6. The method of claim 5 , wherein the chemical treatment agent is selected from the group consisting of scale inhibitors, corrosion inhibitors, paraffin inhibitors, demulsifiers, gas hydrate inhibitors, flocculating agents, asphaltene dispersants and mixtures thereof.

7. The method of claim 1 , wherein the non-spherical particulates are treated with a coating layer or glazing material.

8. The method of claim 1 , wherein the non-spherical particulates are treated with a coating layer which is permeable or semi-permeable to fluids produced from the wellbore.

9. The method of claim 1 , wherein the aspect ratio of the hollow, non-spherical particulates is less than or equal to 2.5:1.0.
