Full title and description

ISO 10426-1:2009 — Petroleum and natural gas industries — Cements and materials for well cementing — Part 1: Specification. This part defines specification-level requirements for the composition, chemical and physical properties, and handling characteristics of well cements used in petroleum and natural gas well construction.

Abstract

Specifies requirements and gives recommendations for six classes of well cements (classes A, B, C, D, G and H), including chemical and physical requirements and procedures for physical testing. It covers Portland-clinker based cements with permitted interground or blended additives and addresses provisions for chromium(VI) reduction where applicable.

Scope

Applies to specification and classification of well cements for petroleum and natural gas industry use, specifying composition, acceptance criteria and required test methods for cement products defined as classes A, B, C, D, G and H. The document is intended to be used where a recognized specification for well cement quality, composition and basic testing requirements is required.

Key topics and requirements

• Definition and classification of six well cement classes (A, B, C, D, G, H) and permitted raw/additive materials.
• Chemical composition limits and physical property requirements (e.g., density, setting behavior, compressive strength tests where specified).
• Specified test procedures and acceptance criteria for physical testing of cements and cement slurries used in wells.
• Requirements for additives and processing agents including notes on set-modifying agents and chromium(VI) reduction measures.
• Reference to corrigenda and technical corrections that modify or clarify the base text (technical corrigenda issued in 2010 and 2012).

Typical use and users

Used by oil and gas operators, cement manufacturers and suppliers, drilling and well construction engineers, testing and quality laboratories, regulatory bodies, and procurement teams who specify or verify the quality of well cement materials for onshore and offshore wells.

Related standards

ISO 10426 is a multipart series. Relevant companion documents include ISO 10426-2 (Testing of well cements) and ISO 10426-3 (Testing of deepwater well cement formulations), which provide detailed test methods and supplementary guidance for specialized environments.

FAQ

Q: What is this standard?

A: ISO 10426-1:2009 is the specification document in the ISO 10426 series that sets classification, chemical and physical requirements, and basic testing/acceptance provisions for well cements used in the petroleum and natural gas industries.

Q: What does it cover?

A: It covers six classes of well cements (A, B, C, D, G and H), allowable additives and manufacturing notes, required physical and chemical property limits, and references to the test methods needed to verify compliance. It also notes provisions related to chromium(VI) reduction where applicable.

Q: Who typically uses it?

A: Oil & gas operators, drilling and completion engineers, cement manufacturers and suppliers, testing laboratories, standards and compliance teams, and procurement specialists involved in specifying or accepting well cement materials.

Q: Is it current or superseded?

A: The 2009 third edition remains the published edition and was reviewed and confirmed by ISO at its periodic review (ISO records show the publication as Edition 3, 2009 and confirmation on review). Technical corrigenda were issued in 2010 (Cor 1) and 2012 (Cor 2) to address corrections; users should apply those corrigenda when implementing the standard.

Q: Is it part of a series?

A: Yes — ISO 10426 is a multipart standard. Part 1 is the specification (this document), Part 2 provides testing methods for well cements, and Part 3 covers testing of deepwater well cement formulations; other related amendments and corrigenda exist across the series.

Q: What are the key keywords?

A: Well cement, cement classes, cement testing, petroleum and natural gas, cement specification, ISO 10426, chromium(VI) reduction.
