    摘要: A method for monitoring hydrocarbon and water production from different production zones/sections in a hydrocarbon reservoir and/or injection wells and detection of different phenomena such as e.g. local variations in pH, salinity, hydrocarbon composition, temperature, pressure, microorganisms, and the difference between production of formation and/or injection water from various zones/sections. The method includes dividing regions around wells in the reservoir into a number of zones/sections, and injecting or placing specific tracers with unique characteristics for each zone/section into the formation in these regions such that tracers are placed as integrated parts of the well completion or placed and immobilized in these regions through injection, squeeze or by other techniques. The tracers can also be immobilized or placed on a filter, a casing or other constructions surrounding the well in each zone/section. The tracers are specific or introduced to give specific information from each zone/section. The method further includes chemically immobilizing or integrating the tracers in the formation or constructions or filters around the wells, the tracers (tracer carriers) being chemically intelligent and released as a function of specific events, and detecting the tracers downstream providing information about the various zones/sections. The method may be used in a local alarm system for water breakthrough or for improved oil and gas recovery (IOR) in horizontal production and injection wells.

    摘要: 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.
