By the end of this course, participants will:
❖ Understand the specific well integrity challenges in brown fields.
❖ Recognize the consequences of well integrity failures and implement preventive measures.
❖ Apply advanced techniques for managing barriers and well performance in brown fields, wells without
barriers or with sustained annulus pressures (SAP).
❖ 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.
❖ Create effective programs for tree and valve maintenance, pressure testing, and barrier installation.
❖ Evaluate industry standards and apply best practices for well integrity in aging fields

This course is designed for:
❖ 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.
❖ Group discussions to foster collaborative problem-solving.
