ISO/TC 67/SC 3/WG 2 - Cementing

This document provides procedures for testing well cements and cement blends for use in the petroleum and natural gas industries in a deepwater environment, or areas with a low seafloor temperature, or areas where low well temperatures exist. This document supplements API RP 10B-3, 2nd edition (2016), the requirements of which are applicable with the exceptions specified in this document. This document excludes the mitigation of shallow water flow in deepwater wells. NOTE This is addressed in API RP 65.

ISO 10426-1:2009 specifies requirements and gives recommendations for six classes of well cements, including their chemical and physical requirements and procedures for physical testing. ISO 10426-1:2009 is applicable to well cement classes A, B, C and D, which are the products obtained by grinding Portland cement clinker and, if needed, calcium sulfate as an interground additive. Processing additives can be used in the manufacture of cement of these classes. Suitable set-modifying agents can be interground or blended during manufacture of class D cement. ISO 10426-1:2009 is also applicable to well cement classes G and H, which are the products obtained by grinding clinker with no additives other than one or more forms of calcium sulfate, water or chemical additives as required for chromium (VI) reduction.

ISO 10426-6:2008 specifies requirements and provides test methods for the determination of static gel strength of cement slurries and related materials under simulated well conditions.

ISO 10426-5:2004 provides the methods for the testing of well cement formulations to determine the dimension changes during the curing process (cement hydration) at atmospheric pressure only. This is a base document, because under real well cementing conditions shrinkage and expansion take place under pressure and different boundary conditions.

ISO 10427-2:2004 provides calculations for determining centralizer spacing, based on centralizer performance and desired standoff, in deviated and dogleg holes in wells for the petroleum and natural gas industries. It also provides a procedure for testing stop collars and reporting test results.

ISO 10426-4:2004 defines the methods for the generation and testing of foamed cement slurries and their corresponding unfoamed base cement slurries at atmospheric pressure.

ISO 10426-2:2003 specifies requirements and gives recommendations for the testing of cement slurries and related materials under simulated well conditions.

ISO 10427-3:2003 describes testing practices to evaluate the performance of cementing float equipment for the petroleum and natural gas industries. ISO 10427-3:2003 is applicable to float equipment that will be in contact with water-based fluids used for drilling and cementing wells. It is not applicable to float equipment performance in non-water-based fluids.

This part of ISO 10427 provides minimum performance requirements, test procedures and marking requirements for casing bow-spring centralizers for the petroleum and natural gas industries. The procedures provide verification testing for the manufacturer's design, materials and process specifications, and periodic testing to confirm the consistency of product performance. This part of ISO 10427 is not applicable to rigid or positive centralizers.

ISO 10426-1:2005 specifies requirements and gives recommendations for eight classes of well cements, including their chemical and physical requirements and procedures for physical testing. ISO 10426-1:2005 is applicable to well cement classes A, B, C, D, E and F, which are the products obtained by grinding Portland cement clinker and, if needed, calcium sulfate as an interground additive. Processing additives can be used in the manufacture of cement of these classes. Suitable set-modifying agents can be interground or blended during manufacture of classes D, E and F. ISO 10426-1:2005 is also applicable to well cement classes G and H, which are the products obtained by grinding Portland cement clinker with no additives other than calcium sulfate or water.

ISO 10426-3:2003 provides procedures for testing well cements and cement blends for use in the petroleum and natural gas industries in a deepwater environment.

Lays down the minimum requirements. Requirements are specified in the second edition of API Recommended Practice 10E (RP 10E), July 1987, which is adopted as ISO 10409. For the purposes of international standardization, modifications have been made that are outlined.
