The results of the substantiation and field testing of the technology of field instrumental quality control of reagents in the article are contained. The list of substances and components included in the composition of oilfield reagents was determined using open sources of information. The component composition is the basis for the choice of spectral analysis methods and instrumental control technology that fill the main classes and the list of oilfield reagents. The experiment confirmed that infrared (IR) spectroscopy and Raman spectroscopy most fully satisfy the conditions, objects and goals of operational control of reagents for production technologies. Laboratory research and field tests have confirmed that IR and Raman spectroscopy methods quantitatively distinguish various brands of oilfield reagents, determine the brand (reagent identification) and authenticity (reagent verification), are suitable for oilfield conditions. This technology provides the ability to record and digitize the composition of an oilfield reagent at each stage of its life cycle “laboratory testing – field testing – field application”. The technology and the digitized IR and Raman spectra allow for a quantitative comparison of the composition and quality of laboratory and field samples of reagents without limitations in terms of storage time, location of laboratory studies and field use. The prospect for the development of technology and method is a) the introduction into the field practice of a digital database IR- and Raman spectra (spectral identifier) of reagents; b) inclusion in reports at the stages “laboratory research – field trials – commercial application”; c) the use of IR and Raman spectrometry for the examination of the quality of reagents during field commercial use.
