As brownfield assets enter late life, executive leadership faces growing pressure to maximise asset value while rigorously controlling operating and maintenance costs. This panel brings together senior industry leaders to discuss how maintenance efficiency, cross asset standardisation, and machine learning solutions deployed at scale are driving sustained reductions in Unit Maintenance Cost (UMC) across mature portfolios. The discussion will focus on the leadership decisions required to move beyond pilot initiatives to enterprise wide adoption, the replication of best practices across diverse assets, and the real world challenges of scaling digital and maintenance programmes.

This panel will also share insights on the governance, capability development, and change management enablers needed to sustain long term value in late life brownfield assets.

As many assets across Asia Pacific enter late-life stages, operators face increasing challenges in sustaining production while operating within tighter economic and operational constraints. Maximising remaining reserves requires not only targeted technical interventions but also integrated brownfield strategies that align reservoir, wells, and facilities decision-making.

This session will discuss how operators systematically identify and prioritise high-impact, cost-effective opportunities to unlock remaining value in mature assets. Through practical experiences and case studies, speakers will share how organisations structure their brownfield optimisation processes and balance technical potential with operational realities.

Discussion topics will include:

• Frameworks and workflows used to identify remaining value in mature assets
• Integrated decision-making across reservoir, wells, and facilities
• Prioritising high-impact interventions under late-life economic constraints
• Optimising infill drilling, recompletions, and well placement in depleted reservoirs
• Improving sweep efficiency and overall production optimisation strategies
• Evaluating fit-for-purpose EOR opportunities for late-life fields
• Managing well integrity, well control risks, and low-margin drilling operations
• Lessons learned from brownfield revitalisation projects across Asia Pacific

Mature brownfield assets present both challenges and opportunities. While operators face increasing technical complexity, rising development costs, and ageing infrastructure, these assets also benefit from existing facilities, established operational baselines, and a deeper understanding of subsurface and surface conditions. Leveraging these advantages while managing integrity and operational risks is key to unlocking near-term value.

This session will discuss structured approaches to accelerating the identification, maturation, and execution of brownfield opportunities to maximise production and economic returns. The focus of the session is on improving opportunity screening, reducing maturation cycle times, and strengthening cross-functional collaboration across subsurface, wells, facilities, and operations. Speakers will also highlight how operators address infrastructure constraints, governance challenges, and organisational bottlenecks that often delay value realisation.

This session aims to share practical methodologies and real-world experiences that help operators accelerate brownfield value creation while maintaining asset integrity, operational reliability, and safe execution.

Discussion topics will include:

• Streamlining opportunity screening, ranking, and prioritisation frameworks for mature assets
• Reducing opportunity maturation cycle time through improved workflows, governance alignment, and integrated planning
• Leveraging multidisciplinary collaboration across subsurface, wells, facilities, and operations teams
• Applying data-driven evaluation techniques to identify near-term, high-value production opportunities
• Overcoming organisational, technical, and process bottlenecks that delay brownfield project execution
• Improving facility readiness through debottlenecking, reliability enhancement, and operational optimization
• Case studies highlighting successful acceleration of brownfield opportunities and lessons learned

As brownfield assets mature, operators are increasingly leveraging digital technologies to improve reliability, reduce operating costs, and extend asset life. Digitalisation, artificial intelligence, and advanced analytics are enabling more proactive asset management by improving visibility of asset performance and supporting faster, data-driven decisions across subsurface, wells, and facilities.This session will discuss how digital tools and predictive technologies are being deployed to enhance production optimisation, asset integrity management, and operational efficiency in mature fields. The focus will be on scalable and practical solutions that can be implemented in resource-constrained brownfield environments.

This session aims to highlight practical applications and case studies demonstrating how digitalisation and predictive technologies can support more efficient, reliable, and sustainable operation of mature assets

Discussion topics will include:

• Deploying digital twins for scenario modelling, production optimisation, and lifecycle planning
• Applying AI/ML-enabled surveillance to detect performance decline and integrity risks early
• Implementing predictive maintenance and condition-based monitoring to reduce Unit Maintenance Cost (UMC) and downtime
• Integrating subsurface, well, and facilities data to enable more effective cross-disciplinary decision-making
• Deploying scalable and cost-effective digital solutions tailored for brownfield assets.
