Abstract

The invention relates to a system and a method for well completion, control and monitoring of processes in a reservoir. A combined prefabricated liner and matrix system (

4) with defined properties for fast and simple well and/or reservoir completion, monitoring and control is provided. An embodiment of the combined prefabricated liner and matrix system

4 includes an outer perforated tubular pipe system

6, an inner tubular screen

7, and a matrix

8. A method for control and monitoring of processes in a well or reservoir using the combined liner and matrix system is also described. The combined liner/matrix system may be used in any process equipment, such as reactors, separators and storage tanks. The system may also be used in a gas/oil/water producing or injection well for well completion, control and monitoring.
