The ASCOPE Decommissioning Guidelines (ADG) Revision 1 provides a unified framework for the safe, efficient, and environmentally responsible decommissioning of oil and gas facilities within ASCOPE member states. It references key international conventions, industry standards, and regional regulations, ensuring alignment with global best practices while addressing ASEAN-specific contexts. This milestone, achieved through the collaborative efforts of the ASCOPE Exploration and Production Task Force.

The guidelines cover the full decommissioning lifecycle, including:

• Pre-Decommissioning: planning, technical and disposal options, environmental assessments, and reporting requirements.

• Execution: procedures and specific considerations for various facility types, including close-out activities.

• Post-Decommissioning: management of residual liabilities and long-term obligations.

Appendices provide practical tools such as report templates, definitions, and examples of liabilities. The ADG serves as a practical reference to support consistent, transparent, and collaborative decommissioning practices across the region.
