This paper demonstrates enhancement of smart completion capabilities by integrating with digital oil field platform for effective performance management of dual lateral wells. Single smart completion with ICVs for controlled comingled production among two reservoirs was successfully deployed and commissioned for 03 oil producers in one of Abu Dhabi green fields.

The multi-position ICVs with customized flow trim design enabled regulating flow from reservoirs downhole and performance monitoring in real time. Additionally with launch of digital oil filed (DOF) in ADMA-OPCO, it is recognized as beneficial using the real time data monitoring to remotely control and operate smart wells for better reservoir management; helping to enhance the smart well system operating reliability. Production performance for one of the EPS smart well is also presented in this paper as a successful case history where the water production for the well was managed below 5% to keep the well flowing and resulted in saving the operating expense (OPEX) by US$ 478 K.

Three approaches were evaluated for flow allocation modeling among the two reservoirs and are presented in this paper i.e. a steady-state nodal analysis network model built in-house, virtual flow estimator (VFE) to provide real time results based on general choke equation and NETFlow (an alternate to VFE) based on a steady state simulator NETool capable of modeling complex lower completions; with later two approaches provided by the vendor and being optimized jointly with ADMA-OPCO. The steady state models are calibrated against the available PLT and real time downhole and surface flow- test measurements.

In the end, some unique issues observed with smart well completions, especially the functionality of the ICVs, are highlighted including the observed anomaly description and associated solutions implemented to restore functionality of some of the smart completion components.

Deployment of smart completions in this green field has resulted in simplifying the completion design and optimizes the number of wells required for field development. Integration of DOF with smart completion system has enabled the team to effectively manage the performance of the reservoirs (especially water production); in the absence of gas lift and continuous down-hole chemical injection during EPS tenure.
