Abstract
The addition of an elastomeric material in intimate mixture with resin-coated particulates for fracturing, gravel packing or other formation treatments decreases or substantially eliminates the flowback of particulates whether proppants or formation fines while stabilizing the particulate and importing elasticity thereto within the formation. Preferred elastomeric materials include, polyolefins, polyamides, polyvinyls and cellulose derivatives in the form of particles, ribbons, fibers or flakes.
Claims20
A method of treating a subterranean formation penetrated by a wellbore comprising the steps of providing a fluid suspension including a mixture of a resin-coated particulate material and elastomeric material;
- pumping the fluid suspension including the mixture into the subterranean formation through the wellbore;
- depositing the mixture of resin-coated particulate and elastomeric material in the subterranean formation whereby the resin-coated particulate is consolidated and the elastomeric material interacts with at least a portion of the particulate to retard movement within said formation of said particulate while providing additional elasticity to said consolidation resin-coated particulate in comparison to said particulate alone whereby breakdown of said consolidated particulate upon application of pressure pulses is reduced.
Method of treating a subterranean formation penetrated by a wellbore comprising the steps of providing a fluid suspension including a mixture of a resin-coated particulate material and an adhesive coated elastomeric material;
- pumping the fluid suspension including the mixture into the subterranean formation through the wellbore;
- depositing the mixture of particulate and adhesive coated material in the subterranean formation;
- and heating the adhesive coated material upon introduction into the subterranean formation whereby the material interacts with at least a portion of the particulate to form a consolidated particulate having additional elasticity in comparison to consolidated resin-coated particulate alone whereby breakdown of said consolidated material upon application of pressure pulses is reduced.
A method of treating a subterranean formation penetrated by a wellbore comprising the steps of providing a fluid suspension including a mixture of a particulate material and an elastomeric material;
- pumping the fluid suspension including the mixture into the subterranean formation through the wellbore;
- depositing the mixture in the formation;
- introducing a resin composition into the wellbore and into contact with at least a portion of the particulate material of said mixture whereby said resin consolidates at least a portion of said contacted particulate material in said mixture with said elastomeric material and said elastomeric material interacts with said particulate to provide additional elasticity to said consolidated particulate in comparison to consolidated particulate alone whereby breakdown of said consolidated particulate upon application of pressure pulses is reduced.
