Physical Characteristics of Proppant


Stim-Lab performs testing under the ISO 13503-2 standard to evaluate proppant characteristics under specified testing conditions in the laboratory.


Tests include:

  • Sieve analysis - grain size distribution
  • Sphericity and roundness (Krumbein shape factor)
  • Acid Solubility-indicates the presence of "impurities" in the sand
  • Turbidity (silt and fine particulate)
  • Crush resistance for 10% K value
  • Apparent density
  • Bulk density-the mass of material that fills a volume, includes both proppant and porosity
