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.

The invention relates to a material wherein the main constituent is PVC for manufacturing pipes to be used for relining underground pipelines by the pipe in a folded condition being drawn into the pipeline and being engaged with the inside surface of the pipeline by temperature increase. By the addition of polymer thermoplastic elastomers which can be mixed with PVC the material has a glass transition temperature ranging from 45.degree. to 75.degree. C. and a ratio (Emod, T=20.degree. C.)/(Emod, T=75.degree. C.)>20. The invention also relates to a method for restoring underground pipes by relining such pipes with a pipe which has been folded after the extrusion.

摘要:
A method for renovation of pipelines, comprising introduction of lining layers into the existing pipeline, the lining layers corresponding in length to the length of the pipeline to be renovated. The lining layers consist of fusible polymers and are presurized and fused together by the introduction of a heat source into the inside of the innermost lining layer.

摘要:
Powder compositions usable to reduce malodours, and powder formulations from which can be made aqueous spray compositions usable to reduce malodours, each comprise, as a major ingredient, amphoteric material, for example sodium bicarbonate, potassium bicarbonate, or zinc oxide, together with one or more minor ingredients, in particular a drying agent, for example sodium sulphate. Other minor ingredients may be an ammonia-odour/sulphide-odour remover, for example ferrous sulphate or zinc sulphate, and an adsorbent, for example zeolite, in the case of a powder formulation; or a filler, for example potassium chloride, or an organic complexing agent, for example cyclodextrin, or a surfactant, in the case of a stock formulation.
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.
