Abstract
A method of fracturing a subterranean formation includes introducing into the formation a fracturing composition comprising a carrier and a substantially spherical polymeric particulate derived from a cashew nut shell liquid, the substantially spherical polymeric particulate having an apparent specific gravity of less than about 2.4. The fracturing composition is introduced at a pressure sufficient to create or enlarge a fracture.

A method of fracturing a subterranean formation, the method comprising:
- introducing into the formation at a pressure sufficient to create or enlarge a fracture in the formation a fracturing composition comprising
- a carrier and
- a substantially spherical polymeric particulate derived from a cashew nut shell liquid, the substantially spherical polymeric particulate having an apparent specific gravity of less than about 2.4 and a particle size of about 10 to 200 mesh.
A method of fracturing a subterranean formation, the method comprising:
- introducing into the formation a slurry containing a carrier and a substantially spherical polymeric particulate derived from a cashew nut shell liquid at a pressure sufficient to create or enlarge fractures in the formation, the substantially spherical polymeric particulate having an apparent specific gravity of less than about 2.4 and a particle size of about 10 to 200 mesh;
- and
- forming in the created or enlarged fracture a proppant pack comprising the substantially spherical polymeric particulate, wherein the proppant pack is permeable to fluids produced from the wellbore and substantially prevents or reduces production of formation materials from the formation into the wellbore.
A sand control method for a wellbore penetrating a subterranean formation, comprising:
- introducing into the wellbore a slurry of a substantially spherical polymeric particulate derived from a cashew nut shell liquid and a carrier, the substantially spherical polymeric particulate having an apparent specific gravity (ASG) of less than about 2.4 and a particle size of about 10 to 200 mesh;
- and
- placing the substantially spherical polymeric particulate adjacent the subterranean formation to form a fluid-permeable pack capable of reducing or substantially preventing the passage of formation particles from the subterranean formation into the wellbore while allowing passage of formation fluids from the subterranean formation into the wellbore.
