Methods are provided that include a method of creating a stable slurry of coated particulates wherein the slurry is capable of being stored for at least 2 hours before use comprising the steps of: providing resin coated particulates wherein the resin comprises a resin that does not completely cure unless it is at least one of exposed to a temperature above about 175.degree. F. or exposed to an external catalyst; and, substantially suspending the resin coated particulates in a servicing fluid to create a stable resin coated particulate slurry. Methods are provided that include a method of creating a stable slurry of coated particulates wherein the slurry is capable of being stored for at least 2 hours before use comprising the steps of: providing tackifier coated particulates; and, substantially suspending the tackifier coated particulates in a servicing fluid to create a tackifier coated particulate slurry.
The present invention relates to methods for making proppants on-the-fly during subterranean treatment operations. Some embodiments of the present invention provide methods of preparing proppant on-the-fly comprising providing discrete amounts of a resin mixture that comprises a resinous material and a filler material; placing the discrete amounts of resin mixture into a well bore comprising a treatment fluid; and, allowing the discrete amounts of the resin mixture to substantially cure and form proppant particles while inside the treatment fluid. Other embodiments of the present invention provide methods of fracturing a portion of a subterranean formation using proppant prepared on-the-fly.
Methods of enhancing uniform placement of a resin in a subterranean formation comprising: introducing a preflush fluid comprising an oil-soluble diverting agent into a portion of a subterranean formation; introducing a resin and an aqueous soluble diverting agent into at least a portion of the subterranean formation; allowing the oil-soluble diverting agent to at least partially dissolve; and allowing the resin to at least partially consolidate at least a portion of the subterranean formation. Optionally, afterflush fluids may be used as desired.
Methods of creating high porosity propped fractures in portions of subterranean formations, including methods of forming a high porosity propped fracture in a subterranean formation comprising providing a slurry comprising a fracturing fluid and proppant particulates substantially coated with an adhesive substance; introducing the slurry into a portion of a fracture within the subterranean formation; and, depositing the proppant particulates into the portion of the fracture within the subterranean formation so as to form a high porosity propped fracture.
