Abstract: Cement bridging is a fundamental technique in wellbore integrity management, widely used in the pet¬ro¬leum industry for well abandonment, zonal isolation, and pressure control. This method involves pla¬cing a cement slurry at a specific depth within the wellbore, where it hardens to form a solid barrier that prevents fluid migration, stabilizes formations, and ensures well integrity. Leading oil and gas operators, implement this technique in both offshore and onshore operations to enhance safety, efficiency, and compliance with industry regulations. Different cementing methods, including the Balanced Plug Method, Stage Cementing, Reverse Circulation Cementing, and High-Pressure Cementing, are employed based on well conditions and operational requirements. These methods help maintain pressure control, prevent cross-contamination between hydrocarbon and water-bearing zones, and provide a foundation for future well modifications. Verification techniques such as pressure testing and tagging ensure the structural integrity of the cement bridge after placement. Advancements in cement formulations and placement technologies continue to improve the effectiveness and reliability of cement bridges, making them a crucial element in modern petroleum engineering. Their strategic application minimizes envi¬ron¬mental risks, ensures regulatory compliance, and optimizes well performance, particularly in challenging deepwater and high-pressure reservoirs. Understanding and applying cement bridging techniques effec¬tively remains essential for maintaining safe and sustainable oil and gas operations. Keywords: cement bridging, wellbore integrity, well abandonment, zonal isolation, pressure control, cement slurry, solid barrier, fluid migration, formation stability.
