Well Cement Integrity offers a comprehensive examination of the critical factors influencing the long-term safety and reliability of wellbore barriers. The book synthesizes recent advances in evaluation techniques, including experimental laboratory testing, field diagnostics, and innovative data-driven methods such as AI and machine learning. It addresses the unique challenges faced in high-pressure, high-temperature, geothermal, and CCUS environments, providing practical guidance for assessing and maintaining cement integrity throughout the entire well lifecycle. The content emphasizes a holistic approach, integrating laboratory assessments, logging tools, pressure testing, and long-term monitoring strategies to enable practitioners to make informed decisions and implement effective remediation measures.The book's structure includes detailed chapters on topics such as cement bond logs, sustained casing pressure, cement plugs, and plug-and-abandonment procedures. It explores the fundamentals of experimental evaluation, discusses the causes and prevention of casing failures, and presents case studies illustrating real-world applications. Additional chapters focus on the evaluation of cement integrity in specialized scenarios like CCUS and geothermal wells, as well as cutting-edge techniques involving AI and machine learning to predict and analyze well performance. Practical procedures and industry standards are incorporated to support effective decision-making and operational excellence. - Summarizes a range of evaluation methods for well cement integrity throughout the lifecycle- Addresses challenges specific to geothermal, CCUS, and high-pressure, high-temperature wells- Incorporates laboratory tests, field diagnostics, and data-driven techniques, including AI/ML- Offers practical guidelines and case studies to support implementation- Supports sustainable energy projects by promoting effective well integrity management
