By the end of this course, participants will: 

1. Understand the specific well integrity challenges in brown fields. 

1. Recognize the consequences of well integrity failures and implement preventive measures. 

1. Apply advanced techniques for managing barriers and well performance in brown fields, wells without barriers or with sustained annulus pressures (SAP). 

1. Develop practical skills for troubleshooting and addressing common well issues, including annulus pressure management and its rigless repair, lack of barriers and lack of data. 

1. Create effective programs for tree and valve maintenance, pressure testing, and barrier installation. 

1. Evaluate industry standards and apply best practices for well integrity in aging fields. 

• Engineers, supervisors, and field operators managing wells in brown and depleted fields. 
• Professionals involved in well intervention, maintenance, drilling, well integrity, production, HSE, completions and abandonment operations. 
• Asset integrity managers seeking strategies for aging infrastructure. 
• Anyone interested in understanding the specific well integrity issues faced in brown field 

The course adopts a hands-on and problem-solving approach, featuring: 

• Interactive presentations on industry standards and best practices. 

• Real-world case studies highlighting common failures and solutions. 

• Practical exercises to develop actionable programs and methodologies.
