Full title and description

ISO 10426-4:2004 — Petroleum and natural gas industries — Cements and materials for well cementing — Part 4: Preparation and testing of foamed cement slurries at atmospheric pressure. This part specifies methods to generate and test foamed cement slurries and their corresponding unfoamed base cement slurries under atmospheric conditions, for use in well cementing operations in the petroleum and natural gas industry.

Abstract

Defines procedures for the generation of foamed cement slurries and associated test methods (including preparation of unfoamed base slurries) at atmospheric pressure, and gives standardized measurements and acceptance practices for laboratory evaluation of foamed well cements.

Scope

This part of ISO 10426 specifies methods for the generation and laboratory testing of foamed cement slurries and their corresponding unfoamed base cement slurries at atmospheric pressure. It is intended to provide repeatable, comparable procedures for preparing foamed slurries and for measuring their properties in controlled laboratory conditions.

Key topics and requirements

• Standardized preparation procedures for foamed cement slurries (generation of foam and incorporation into cement slurry).
• Methods to prepare corresponding unfoamed base cement slurries for comparison and control testing.
• Laboratory test methods and property measurements relevant to foamed slurries at atmospheric pressure (density control, stability, rheology and other laboratory-evaluated properties as defined in the standard's test methods).
• Requirements for repeatability and reporting of test conditions and results to enable comparison between laboratories and formulations.

The above topics summarize the principal technical content of ISO 10426-4:2004.

Typical use and users

Primary users are drilling, cementing and completion engineers, laboratory technicians, materials scientists and manufacturers/suppliers of well cements and cementing additives. The standard is used for laboratory evaluation of foamed cement formulations, quality control, R&D of cement blends for wells, and pre-job testing prior to field cementing operations.
