Proppant Standards… API ISO and ASTM what are they and why you should care.
If you’ve spent any time perusing proppant producer websites, you will likely see acronyms and numbers intended to depict the company’s commitment to quality. But what does it mean?
We are going to chronologically list relevant standards for the evaluation of proppant used in hydraulic fracturing and illustrate which standards are obsolete or inactive and eventually discern which one is the industry’s most complete and up to date document.
RP 56 – Recommended Practice – March 1, 1983 – Inactive
Recommended Practices for Testing Sand Used in Hydraulic Fracturing Operations First Edition
RP 56 – Recommended Practice – December 1, 1995 – Inactive
Recommended Practices for Testing Sand Used in Hydraulic Fracturing Operations First Edition
Scope: The objective of these recommended practices is to provide control of frac sand quality at the well site. As a first step in accomplishing this objective, the recommended tests should be applied at the basic point of supply where quality control is first exercised.
ISO 13503-2 – November 1, 2006 – Active – pending update
Petroleum and natural gas industries – Completion fluids and materials – Part 2: Measurement of properties of proppants used in hydraulic fracturing and gravel-packing operations
API RP 19C – Recommended Practice – May 1, 2008 -Obsolete
Measurement of Properties of Proppants Used in Hydraulic Fracturing and Gravel-packing Operations
API STD 19C – Standard- August 1, 2018 – Most Current
Measurement of and Specifications for Proppants Used in Hydraulic Fracturing and Gravel-packing Operations
Well, That’s it. The most current standard for use in evaluating proppant quality is the API STD 19C published on August 1, 2018.
Now, by knowing this information you are better prepared to evaluate your sand providers and third-party testing companies. If they are still referencing outdated, inactive, or obsolete standards for evidence of providing quality products or services, its likely fair to assume that they may not be taking their quality obligations seriously.
