About Course

The Well Plug & Abandonment Engineering course provides a structured introduction to the principles, practices, and decision-making required to deliver safe and compliant well abandonment. Aligned with international standards such as NORSOKD-010, the course emphasizes barrier philosophy, long-term integrity, and risk-based thinking.

Through five focused modules, participants explore regulatory context, subsurface risk, barrier systems, abandonment methods, cost estimation principles, and execution best practices. Interactive quizzes, practical examples, and real-world case studies reinforce learning throughout the course.

This e-learning program is designed for engineers, supervisors, specialists, regulators, and professionals new to well abandonment who require a clear, practical understanding of how abandonment decisions influence safety, environmental protection, and long-term liability.
