Recommended Practices for Testing High Strength Proppants Used in Hydraulic Fracturing Operations
American Petroleum Institute Washington, D.C. 20005
Similar to API RP-56 for fracturing sands, these procedures were developed by the American Petroleum Institute to assist in quality control of high strength proppants. The procedures cover the following general topics:
- Procedures recommended to obtain a representative sample
- Sample handling and storage
- Recommended sieve analyses
- Sphericity and roundness determination
- Acid solubility
- Crush resistance testing
Determination of bulk density, and apparent specific gravity of proppants |
