Integrity Assessment Through Numerical Simulations,ken into account as most components (like rock or cement) in a wellbore may display substantial nonlinearity and history dependence. We review various modeling aspects explored to simulate wellbore integrity problems in this chapter.

Well Integrity Assurance, interventions. This chapter introduces the primary and secondary well barriers and explain how they act together to prevent fluid migration during drilling, production, and after plugging and abandonment. The design criteria, location, and evaluation of each barrier element are thoroughly analyzed, and the potential failure modes are explored.

Field Operations: Requirements and Impacts,nd may be more demanding on particular barriers. Each operation is briefly described, and their technical requirements are reviewed, with recommendations for well barriers, preceding operations, and monitoring protocols to minimize risk. Furthermore, we explore the causes and consequences of failure to comply with these requirements.

Remediation Techniques,ed to address these challenges that are classified into two categories: the rig methods and rig-less methods. In this chapter, we are going to review these methods and describe the challenges involved in their field implementation. We also analyze how to evaluate the remediation jobs and what makes them successful.

Well Plugging and Abandonment,underground freshwater sources. A plug can be defined as any object or equipment inserted into the wellbore with the intent of obstructing a hole or passageway. Only after the well is properly isolated, surface structures may be removed. In this chapter, we are reviewing various steps of P&A and the challenges for each step.
