1 Scope This document provides specifications and standard testing procedures for evaluating proppants used in hydraulic fracturing and gravel-packing operations.

The objective of this document is to provide specifications and a consistent methodology for testing performed on hydraulic fracturing and/or gravel-packing proppants. Methodologies and specifications (where applicable) are provided for:

  • sieve analysis and median diameter determination;
  • sphericity and roundness;
  • acid solubility;
  • turbidity;
  • loose pack bulk density, apparent density, and absolute density;
  • crush resistance;
  • loss on ignition.

Proppant size designation is as per industry standard. It is based on the maximum and minimum size determination by sieve analysis and ASTM 1 sieve number (and not as per standard opening expressed in micrometers). Proppants in this document are sand, ceramic media, resin-coated proppants, gravel-packing media, and other similarly used materials for hydraulic fracturing and gravel-packing operations.
