Overview

prEN ISO 10426-2 (ISO/DIS 10426-2:2019) - "Petroleum and natural gas industries - Cements and materials for well cementing - Part 2: Testing of well cements" - provides standardized procedures for laboratory testing of cement slurries and hardened cement under both atmospheric and simulated downhole conditions. This part supplements API RP 10B-2 (2nd edition, 2013) with clarifications, updates and additional test methods relevant to well cementing operations in the petroleum and natural gas industries.

Key topics and technical requirements

• Scope and applicability

  • Test methods apply to ISO cement Classes A, C, G and H, high‑alumina cement and ductile cement compositions.
  • Includes instructions for presenting results in SI with United States customary (USC) units where practical.

• Supplements to API RP 10B-2

  • Specifies exceptions and amendments to API RP 10B-2 where ISO 10426-2 diverges (for example, temperature ranges, formula coefficients and procedural details).

• Well-simulation compressive-strength tests

  • Procedures for sample preparation and curing under simulated downhole conditions; adjustments to temperature ramps and curing vessel requirements are included.

• Non‑destructive sonic determination of compressive strength

  • Calibration and formula adjustments for sonic testing of hardened cement to estimate compressive strength without destructive sampling.

• Static fluid‑loss tests

  • Test methods for measuring static fluid loss of cement slurries with specific procedural revisions to API RP 10B-2 referenced text.

• Rheology and gel‑strength determination

  • Use of rotational viscometers to determine rheological properties and gel strength; specifies shear-rate references and clarifies interpretation of flow models (e.g., Bingham plastic reduction conditions).

• Document updates

  • Omits standardized well cementing schedules and certain pressure-drop and permeability tests (considered obsolete or unreliable) and adds/updates several test methods compared to the previous edition.

Applications and users

• Intended for: drilling and completion engineers, cementing service companies, laboratory technicians, material manufacturers, quality assurance personnel and regulatory/standards bodies.
• Practical uses:
  • Designing and validating well cement slurries for zonal isolation and well integrity.
  • Laboratory qualification of cement products and additives under simulated downhole conditions.
  • Non‑destructive monitoring of cured cement compressive strength and performance verification.

Foreword
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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
