Intelligent, or Advanced Well Completions (AWC) contain a series of Flow Control Devices (FCDs) installed in the production tubing along the well production or injection interval. This helps controlling the inflow or outflow profile for a number of reasons: reduction of unwanted fluid production; improved sweep efficiency; zonal flow control; etc. In addition, the permanently installed in-well sensors provide a range of real-time measurements that are used for effective well and reservoir monitoring.
This lecture will give a general overview of the intelligent well control technology, its applications, and methods well completion modelling, well design, well and reservoir monitoring, and production optimization of advanced well completions.
In particular:
1. Completion and Production Optimization Techniques for Advanced Wells & Fields.
This part concentrates on the application of the advanced well completion and development of well/field control methodology. The methodology uses optimization tools for the optimal production set-up, robust well production or injection control, reduction in reservoir uncertainty. Proactive and reactive methods of the production control are discussed. A range of reservoir and inflow conditions are analyzed.
2. Advanced Well Completion Design, Modelling and Critical Analysis.
Advanced well completions include both active & passive options for selective downhole flow control. Complimentary downhole monitoring devices allow efficient, flexible production control of these completion systems. Static and dynamic well completion design methods and ideas are developed and analyzed. Comparison and screening methodology for the different completion types is presented and supported by numerical and analytical studies. The full range of downhole control devices is discussed.
3. Monitoring in Advanced Wells and Interpretation of Measured Data.
Advanced well monitoring systems provide the raw data which custom algorithms can turn into real-time information that quantifies the multiphase flow rate distribution across the well’s multiple completion intervals.
This transformation of data into information is the first step in real-time, selective, zonal production management methodology. Downhole monitoring systems are reviewed followed by the development of the data interpretation methodologies both available and novel. Those include zonal flow rate allocation in real time, data and model driven analysis such as intergraded data pre-screening, and pressure and temperature transients.
