Abstract
Introduction and aim. At the moment, there is no single document in the industry regulating the interpretation of the results of studies of samples distorted with respect to a particular state of the reservoir fluid. As a result, the absolutely correct statement that each sample carries information about the properties of the object under study is often misunderstood and the parameters of the samples are taken into averaging without analyzing their history and properties. Solving this problem is a basic task for creating a methodological and technological basis for improving the qualitative knowledge of reservoir fluids.
Materials and methods. The methods of a systematic approach, expert survey and thought experiment were used in the development.
Results. A terminological system is presented to describe the process of interpreting fluid information; correlations used in this analysis are classified; a typology of distortions in the properties of reservoir oil and some areas of its application are proposed.
Conclusion. It is recommended to use the proposals in the It is recommended to use the proposals in the Development of normative and methodological documentation in the fi eld of expert examination of the properties of reservoir fluids.
Supporting agencies: this work was funded by the subsidy allocated to Kazan Federal University for state assignment in the sphere of scientific activities (Project no. FZSM-2024-0003).
