Plugging and Abandonment of Oil and Gas Wells Course
Introduction:
Well Abandonment is commonly the largest area of expenditure in decommissioning oil and gas production assets and is often the area of largest cost overruns. Abandonment at the end of well life provides some unique challenges to the engineer, company finances, and the regulator due to the multiple objectives of minimizing both risks to the environment and overall expenditure.
The strategic nature of decommissioning, and particularly abandonment, has only recently been recognized, with the growing impact on Company balance sheets, personnel competency requirements, regulation, and legislation now in the spotlight in many organizations. Lessons can be learned from recent industry experience to ensure organizations are ready to manage their responsibilities and obligations effectively and to improve the industry’s performance in the future.
