A Novel Field Development Strategy: Case Study on the Effective Application of Smart Completions

The effective development of complex reservoirs requires completion strategies that enable both selective zonal production and controlled commingled production across multiple reservoirs. Smart completion technologies provide the capability to achieve this dual objective by integrating inflow control devices, zonal isolation, and real-time monitoring systems. This case study presents the deployment of ADNOC Onshore's first smart completion for dual-reservoir production, designed to optimize selective inflow control while enabling commingled production. The installation incorporated Inflow Control Valves (ICVs), Permanent Downhole Gauges (PDHGs), and dual-sensor monitoring to achieve enhanced zonal isolation, dynamic production balancing, and improved well integrity. The solution facilitated real-time inflow/outflow control, reducing intervention requirements and enhancing sustained reservoir contribution from both zones. To maximize the value of smart completions, a hybrid physics and data-driven workflow was implemented. This workflow combined proxy reservoir models, well performance modelling, and data driven surveillance tools to deliver continuous inflow monitoring, zonal allocation, and production optimization. The integration of physics-based analysis with data analytics enabled proactive identification of production anomalies, efficient water cut and GOR management, and reliable allocation of commingled volumes across the two reservoirs. Results obtained demonstrated improved production performance, delayed water breakthrough, and higher well availability compared with conventional completions. Operational savings were realized through the elimination of rig-based workovers, reduced reliance on wireline logging for zonal contribution, and optimized reservoir management through automated surveillance and control. This case study highlights a novel field development strategy that integrates smart completion hardware with advanced hybrid workflows. The demonstrated approach provides actionable best practices for operators seeking to enhance recovery efficiency, ensure reliable surveillance, and optimize dual-reservoir management in complex field environments.
