XOProp™ Expandable Proppant


XOProp™ Expandable Proppant

XOProp™ is a patent-pending expandable proppant based on phase change composites that react to the downhole environment to expand in a controllable manner and apply force, in-situ. This expansion can be accomplished while retaining permeability, and is uniform, irreversible, controlled, and has the capability to exert forces of over 10,000 PSI.

Geo Mechanical modeling conducted by FracGeo indicates that XOProp’s ability to offset closure forces, and extend open times and fracture aperture sizes can enable an approximate 23% increase in production over the first several years of well operation.


  • Large volumetric expansion in rigid (GPa) high stiffness system
  • Ability to expand fractures and apply force while retaining permeability
  • Can be produced in 100 mesh to mm sizes
  • Stiffness, timing, and operating temperature ranges can be tailored
  • ~23% increase in production over the first several years of well operation
  • 100% Made in the U.S.A

XOProp™ is currently available in pilot plant quantities for Testing. If you have an interest in learning more about this exciting product, please download the brochure to learn more.
