As operators face declining production, ageing infrastructure, and rising operational costs, implementing cost-effective strategies to maximise recovery from marginal and mature fields is critical. This session will explore innovative and practical solutions that boost recovery and ensure sustainable, long-term energy security.

Topics to be discussed include:

• Cost-effective methods to extend field life and optimise late-life production
• Leveraging digitalisation and data-driven insights to improve field performance
• Repurposing existing facilities and infrastructure for extended operations
• Deploying of fit-for-purpose technologies to enhance recovery and efficiency
• Regulatory, financial, and collaboration models enabling practical developments in a competitive energy landscape
• Case studies and benchmarks showcasing successful, cost-effective revitalisation of marginal and mature field

This session will highlight case studies on the redevelopment and optimisation of marginal and mature fields across the region. It will examine how integrated reservoir management, improved oil recovery (IOR) applications, and targeted infill drilling campaigns have been applied to maximise recovery and sustain production in declining reservoirs.

Topics to be discussed include:

• Fit-for-purpose facility designs for modular, phased, and cost-effective developments
• Integration of subsurface and surface strategies to enhance field performance
• Lessons learnt from IOR and infill drilling programmes, including both successes and challenges
• Evaluation of commercial frameworks such as late life asset (LLA) and small field agreement (SFA) models
• Strategies to align technical, operational, and economic priorities for long-term value creation
• Case studies demonstrating successful redevelopment and optimisation of marginal and mature fields
