Abstract:
Well integrity management is crucial for ensuring oil and gas operations' safety, reliability, and sustainability. This paper comprehensively reviews key aspects and strategies in Well integrity management and optimization. It explores fundamental concepts, including the definition of Well integrity, its components such as casing and cementing, and the life cycle phases from drilling to abandonment. Regulatory and industry standards, such as those set by API and ISO, are examined for their impact on Well integrity practices. Techniques for Well integrity management encompass monitoring and diagnostic tools like pressure testing, logging tools, and sensors, which play a pivotal role in assessing the condition of Well components. Maintenance and repair techniques, including innovative methods and materials, are essential for preserving Well integrity and minimizing operational risks. The paper also delves into optimization strategies such as predictive maintenance using AI and machine learning, digitalization through digital twins and IoT technologies, and cost-benefit analysis to optimize economic efficiency while ensuring safety and compliance. Emerging technologies like blockchain and advanced materials are discussed for their potential to revolutionize future practices in Well-integrity management. Challenges in the industry, such as aging infrastructure and environmental sustainability, are highlighted alongside opportunities for innovation. Strategic recommendations are provided for industry stakeholders to enhance Well integrity management through research and development, sustainable practices, standardization of best practices, and continuous workforce development.
