This paper revisits Indonesia’s Idle Wells Reactivation Program, initially launched to unlock hydrocarbon potential from inactive wells while boosting national energy production. Over the past four years, the program has achieved significant milestones, including the successful reactivation of wells across key basins, enhancing the nation's energy security. The paper details the approach, from selecting idle wells based on technical and economic viability to implementing innovative reactivation technologies.

Challenges, such as environmental concerns, regulatory hurdles, and logistical issues, particularly in remote areas, are also analyzed. Lessons learned have led to improved operational efficiency and sustainability.

Additionally, addressing idle wells not only transforms liabilities into profitable revenue but also prevents environmental damage. Wells left idle without maintenance may face well integrity issues, including leaks that contaminate soil and groundwater, or release methane, a potent greenhouse gas. By reactivating and properly maintaining these wells, such risks are mitigated, avoiding environmental hazards while protecting ecosystems and communities.

If reactivation is not feasible, proper plugging and abandonment techniques are employed to prevent future leaks. Thus, the program delivers both economic and environmental benefits, ensuring responsible and safe energy practices.

Finally, the paper outlines a path to a greener future by emphasizing safe planning in the reactivation process and the integration of enhanced monitoring systems. Safe planning ensures that the reactivation of idle wells is conducted with a focus on minimizing environmental risks, such as well integrity issues and potential leaks. By adopting these measures, the program ensures that reactivated wells operate safely and sustainably, contributing to minimal environmental impact while maintaining economic viability.
