Overview

EN ISO 13503-2:2024 - titled Completion fluids and materials - Part 2: Measurement of properties of proppants used in hydraulic fracturing and gravel-packing operations - is a CEN-endorsed international standard that defines laboratory test procedures for evaluating proppants (sand, ceramic, resin-coated and gravel-packing proppants and similar materials). It updates and supplements API Std 19C (2nd edition, 2018) to provide a consistent, modern methodology for proppant testing used in hydraulic fracturing and gravel-packing.

Key topics and technical requirements

• Scope and purpose: Standardizes test methods for proppant particle size distribution, crush resistance and other key properties used in completion operations.
• Relationship to API Std 19C: Supplements and references API Std 19C; where applicable, API requirements apply except where EN ISO 13503-2 specifies deviations.
• Sampling: Introduces a stand sampling device for proppants packed in 1.5 t bags. Sampling guidance includes taking samples from upper, middle and lower bag sections, inserting the device to 3/4 length, and collecting a minimum total sample mass of 25 kg (which may be split into 3 kg portions).
• Sieve analysis: Revised procedure requires inverting and brushing sieves to remove adhering grains, then weighing retained material on each sieve and in the pan. Specifications include that a minimum of 90% by mass of a tested sample should pass the coarse designated sieve and be retained on/above the fine designated sieve (common size bands: 1700/850 μm, 850/425 μm, 425/250 μm). Limits on oversize and fines are tightened (e.g., max 0.1% larger than the first sieve; remaining material on last sieve/pan updated to not exceed 2%).
• Crush resistance testing: Uses a PropPaver loading device (replacing the Pluviator) to lay out a flat, reproducible proppant pack in the crush cell and reduce operator variability. Sample preparation, designated sieve sizes and a 10-minute shaking duration are maintained or clarified.

Applications and users

Who benefits:

• Completion and production engineers specifying proppant selection for hydraulic fracturing and gravel-packing
• Quality control and testing laboratories performing proppant acceptance tests
• Proppant manufacturers and suppliers for product certification and compliance

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

This second edition cancels and replaces the first edition (ISO 13503-2:2006), which has been technically
revised. It also incorporates the Amendment ISO 13503-2:2006/Amd 1:2009.
This document supplements API Std 19C, 2nd edition (2018).
The technical requirements of this document and API Std 19C used to be identical. In the meantime API
Std 19C has been technically revised as API Std 19C, 2nd edition (2018). The purpose of this edition
of ISO 13503-2 is to bring it up to date, by referencing the current edition of API Std 19C and including
supplementary content.
The main changes are as follows:
— a new stand sampling device has been used for proppant packed in bags;
— proppant on the sieves has been removed and directly weighed in sieve analysis testing;
— the average diameter calculation has been added;
— the remaining total amount on the last sieve and in the pan has been updated to not exceed 2 % by mass
of the total tested proppant sample;
— PropPaver loading device has been used instead of Pluviator loading device;
— the upper and lower designating sieve sizes have been kept for sample preparation and after pressurizing
in crush resistance test;
— shaking durati
