ISO 10426-4:2004 PDF Download

ISO 10426-4:2004 is a standard that specifically focuses on the preparation and testing of foamed cement slurries at atmospheric pressure within the petroleum and natural gas industries. The standard outlines the methods and procedures for producing foamed cement slurries as well as their corresponding unfoamed base cement slurries.

The standard provides guidelines for the generation of foamed cement slurries, including the required equipment and additives, as well as the appropriate mixing procedures. It also specifies the characteristics and properties that need to be measured and tested, such as density, thickening time, compressive strength, and thermal stability.

The purpose of ISO 10426-4:2004 is to ensure that foamed cement slurries used in well cementing operations meet the necessary performance requirements, including stability and long-term durability. By following the procedures outlined in the standard, operators and cementing engineers can ensure a consistent and reliable quality of foamed cement slurries, which are crucial for successful well cementing operations in the oil and gas industry.
