Full title and description

ISO 10426-3:2019 — Petroleum and natural gas industries — Cements and materials for well cementing — Part 3: Testing of deepwater well cement formulations. This part gives procedures for laboratory testing of well cements and cement blends intended for use in deepwater environments or where low seafloor / well temperatures exist; it is written to supplement API RP 10B-3 (2nd edition, 2016) and explicitly excludes mitigation of shallow-water flow.

Abstract

This short International Standard specifies procedures for laboratory testing of deepwater well cement formulations and cement blends used in petroleum and natural gas wells in locations with low seafloor or low downhole temperatures. It supplements the test recommendations of API RP 10B-3 (2016) and lists the exceptions where ISO 10426-3 applies; shallow-water-flow mitigation is outside its scope. Edition 2 was published in August 2019.

General information

• Status: Published.
• Publication date: 2019-08 (August 2019).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 75.020 (Extraction and processing of petroleum and natural gas) / 91.100.10 (Cement).
• Edition / version: Edition 2 (2019).
• Number of pages: 4 pages (concise technical specification / test-procedure supplement).

Scope

Specifies laboratory procedures for testing well cement and cement blends for deepwater applications or in regions where the seafloor or well temperatures are low. The document is intended as a supplement to API RP 10B-3 (2nd edition, 2016) — that API document's requirements apply except where ISO 10426-3 specifies otherwise. The standard does not cover mitigation measures for shallow water flow in deepwater wells.

Key topics and requirements

• Procedures for preparing and testing cement slurries and blends intended for deepwater/low-temperature conditions.
• Guidance on how ISO testing requirements interact with API RP 10B-3 (2016) — ISO 10426-3 supplements and, where applicable, modifies API procedures for the deepwater context.
• Clear statement that mitigation of shallow water flow is excluded from the scope (refer users to other guidance such as API RP 65 for related topics).
• Concise, focused technical content (standard is a short supplement rather than a comprehensive test-method compendium).

Typical use and users

Used by oil & gas operators, well-cementing service companies, cement manufacturers, petroleum testing laboratories, completion and drilling engineers, and regulatory or inspection bodies that require standardised laboratory testing of cements intended for deepwater or low-temperature wells.

Related standards

Part of the ISO 10426 series on cements and materials for well cementing (see ISO 10426-1, ISO 10426-2, ISO 10426-4, ISO 10426-5, ISO 10426-6, etc.). It specifically supplements API RP 10B-3 (Testing of deepwater well cement formulations) and aligns with work from ISO/TC 67/SC 3 (Drilling and completion fluids, well cements and treatment fluids).

FAQ

Q: What is this standard?

A: ISO 10426-3:2019 is Part 3 of the ISO 10426 series; it provides laboratory test procedures for well cements and cement blends intended for deepwater or low-temperature petroleum wells.

Q: What does it cover?

A: It covers test procedures and related provisions for evaluating cement formulations under deepwater or low-temperature conditions and indicates where API RP 10B-3 (2016) should be followed or supplemented. It explicitly excludes shallow-water-flow mitigation measures.

Q: Who typically uses it?

A: Cement manufacturers, well‑casing and completion service providers, oil & gas operators, laboratory technicians running cement tests, drilling and completion engineers, and technical regulators or auditors.

Q: Is it current or superseded?

A: Edition 2 was published in August 2019. According to ISO’s record the 2019 edition is the current published version (the 2003 edition was withdrawn and replaced by the 2019 edition). Users should check ISO or their national standards body for any subsequent confirmations or revisions.

Q: Is it part of a series?

A: Yes — ISO 10426 is a multipart series covering cements and materials for well cementing (Parts 1, 2, 3, 4, 5, 6, etc. address specification and various test and measurement methods). ISO 10426-3 specifically addresses deepwater testing.

Q: What are the key keywords?

A: Deepwater cement testing; well cementing; cement blends; low-temperature testing; ISO 10426; API RP 10B-3 supplement.
