A multi-test assembly for evaluating, detecting and monitoring processes at elevated pressure is described. The Mufti-test assembly has a pressure vessel equipped with trays or plates with a multitude of individual test cells, an optional lid for sealing the cells, and a system for the detection and/or monitoring of the processes in each individual test cell, in situ. Uses of the invention are detection of solid structure formation or phase transformation in, for example, hydrocarbon systems or mixtures of hydrocarbon and water, and also in an automated test which is optimized simultaneously with regard to several test parameters in the testing of inhibitors for gas hydrate formation. The multi-test assembly has built-in systems for pressure and temperature control. The assembly may also be connected to a set-up for the automatic dosing of reagents.

Multi-test assembly for evaluating, detecting and mountoring processes at elevated pressure

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 ( ) 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 includes an outer perforated tubular pipe system , an inner tubular screen , and a matrix . 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.

Combined liner and matrix system

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.
