𝗪𝗲𝗹𝗹 𝗜𝗻𝘁𝗲𝗴𝗿𝗶𝘁𝘆 is a fundamental concept in drilling and production, focusing on maintaining a wellbore that is properly sealed to ensure safe fluid containment throughout the well’s life. Without proper management, compromised well integrity can result in blowouts or contamination, making it crucial to maintain control and oversight throughout the well’s life cycle. 

𝗪𝗵𝗮𝘁 𝗶𝘀 𝗪𝗲𝗹𝗹 𝗜𝗻𝘁𝗲𝗴𝗿𝗶𝘁𝘆? 

Well integrity refers to a well's ability to safely contain and control fluids, ensuring the protection of people, the environment, and infrastructure. This involves maintaining well structures such as casing, tubing, and cementing to prevent leaks or failures, guaranteeing control over fluid flow within the well. 

𝗪𝗲𝗹𝗹 𝗕𝗮𝗿𝗿𝗶𝗲𝗿𝘀 

Well barriers are essential for maintaining well integrity and preventing the uncontrolled release of fluids. Key examples include: 

• 𝗕𝗹𝗼𝘄𝗼𝘂𝘁 𝗣𝗿𝗲𝘃𝗲𝗻𝘁𝗲𝗿 (𝗕𝗢𝗣): A surface barrier that prevents uncontrolled pressure release. 

• 𝗖𝗲𝗺𝗲𝗻𝘁 𝗕𝗮𝗿𝗿𝗶𝗲𝗿𝘀: Seal the wellbore between casing and formation to prevent fluid migration. 

• 𝗪𝗲𝗹𝗹𝗵𝗲𝗮𝗱/𝗖𝗵𝗿𝗶𝘀𝘁𝗺𝗮𝘀 𝗧𝗿𝗲𝗲: Controls pressure and isolates the wellbore. 

• 𝗗𝗼𝘄𝗻𝗵𝗼𝗹𝗲 𝗦𝗮𝗳𝗲𝘁𝘆 𝗩𝗮𝗹𝘃𝗲𝘀 (𝗗𝗛𝗦𝗩): Prevent uncontrolled fluid flow in case of failure. 

• 𝗣𝗮𝗰𝗸𝗲𝗿: Isolates sections of the wellbore to prevent fluid movement. 

• 𝗜𝘀𝗼𝗹𝗮𝘁𝗶𝗼𝗻 𝗣𝗹𝘂𝗴𝘀: Isolate specific zones, particularly during abandonment or intervention. 

• 𝗧𝘂𝗯𝗶𝗻𝗴 𝗦𝘁𝗿𝗶𝗻𝗴/𝗖𝗮𝘀𝗶𝗻𝗴: Controls fluid flow and acts as a critical barrier when combined with safety valves. 

Well integrity is maintained throughout the well’s life cycle, from planning and design to construction and installation, monitoring and maintenance, and compliance and documentation, ensuring the well remains secure, functional, and compliant with safety and environmental standards.
