This paper describes an innovative completion solution with state-of-the-art reservoir monitoring and control completion technologies that allows commingled oil production from quad laterals wells in Abqaiq field. Many intelligent completions wells have been successfully installed in Abqaiq, operated by Saudi Aramco. Included in the description are equipment selection, design and development details, installation procedures, and "lessons learned" after installation of the fully hydraulic tubing-retrievable advanced completion system with digital permanent down hole monitoring system.

Intelligent completions will allow individual lateral testing and allocation of production rates to optimize each lateral contribution and the overall commingled well rate. Along with real time monitoring, sustainability of well rate will be extended by timely reacting to any changes to reservoir and well conditions.

Using variable-position flow control valves, early water breakthrough can be delayed, to increase recovery. Monitoring the flowing pressure in real time allows producing the well at optimum rate; i.e., above bubble point pressure. Ultimately, intelligent completions will limit the water handling at the surface and concurrently increase the recovery factor in heterogeneous fractured and fissured carbonate reservoirs for MRC (Maximum Reservoir Contact) wells.
