Corrosion Monitoring Concept for Oil Wells

This “Master of Science” thesis deals with the creation of a corrosion monitoring concept of oil wells. In the end, the reader should have a deeper understanding regarding important parameters affecting corrosion, parameters to be measured in terms of corrosion surveillance and the connected prevention of metal deterioration. At the beginning, a theoretical background is provided to create an overview on corrosion issues. As a second step, a field data analysis of oil wells in Austria is being performed, where critical parameters are screened and checked for validity. Field data investigations do not show a good match according to literature and so reliable outputs, like an optimum dose of inhibitors to be injected downhole, can not be published by means of field data investigations only. That is why autoclave experiments, with respect to selected field data parameters, have been performed and results, indicating clear trends towards critical questions, are being published at the experimental section in this work. At the end of this work, guidelines for a measurement concept are recommended to achieve a reliable feedback by means of routine measurements.
