Overview

oSIST prEN ISO 10426-2:2019 focuses on standardized procedures for the testing of well cements in the context of petroleum and natural gas industries. Developed by CEN and ISO, and adopted by SIST, this draft international standard details test methods used to evaluate cement slurries and hardened cement at both atmospheric and downhole (wellbore) conditions. It addresses updates from previous editions and references the latest requirements in API RP 10B-2 (2nd edition, 2013). The standard is designed to ensure consistent quality and performance in well cementing operations, crucial for safe, effective oil and gas extraction.

Keywords: well cement testing, petroleum industry standards, natural gas cementing materials, ISO 10426 series, API RP 10B-2, downhole cement tests, oil & gas quality control, cement slurry evaluation

Key Topics

• Scope and Applicability

  • Covers testing procedures for various cement types, including Classes A, C, G, H (ISO 10426-1), high-alumina cement, and specialized ductile cements.
  • Applies to tests performed under both laboratory and simulated well conditions.

• Supplementary Requirements to API RP 10B-2

  • Updates and clarifies specific testing steps from the referenced API recommended practice.
  • Omits outdated or unreliable procedures, reflecting current industry practices.

• Test Method Highlights

  • Compressive-Strength Testing: Methods for determining well-simulation compressive strength, ensuring cement can withstand downhole pressures and maintain borehole integrity.
  • Non-Destructive Sonic Testing: Procedures for sonic measurement of compressive strength, providing alternative, less invasive ways to validate cement hardening.
  • Static Fluid-Loss Testing: Guidelines for measuring fluid loss from cement slurries, which can impact zonal isolation and cement setting.
  • Rheological Properties Assessment: Using rotational viscometer techniques to evaluate gel strength and flow characteristics of cement slurries, essential for proper placement and pumpability.

Applications

The practical value of oSIST prEN ISO 10426-2:2019 is realized in its direct application to upstream petroleum and natural gas activities, such as:

• Cement Quality Assurance: Ensures well cementing materials meet consistent, internationally recognized test standards for mechanical performance and durability.
• Operational Safety: Reliable test results help prevent cement sheath failures, minimizing risks of blowouts, gas migration, or reservoir contamination.
• Regulatory Compliance: Provides standardized testing protocols that support compliance with industry and governmental regulations, mitigating legal and environmental risks.
• Field and Laboratory Use: Supports both in-lab research and routine on-site quality control in drilling operations, enabling verification of cement properties under real-world conditions.

Related Standards

For a comprehensive approach to well cementing in the petroleum and natural gas industries, consider these related standards:

• ISO 10426-1: Petroleum and natural gas industries - Cements and materials for well cementing - Part 1: Specification
• API RP 10B-2: Recommended Practice for Testing Well Cements (2nd edition, 2013)
• ICS Codes: 75.180.10 (Exploratory, drilling and extraction equipment); 91.100.10 (Cement, gypsum, lime, mortar)

oSIST prEN ISO 10426-2:2019 is an essential part of the ISO 10426 series, supporting the safe and efficient development of oil and gas wells through standardized cement testing procedures. Use of this standard promotes reliability, safety, and consistency in well cementing worldwide.
