This paper presents the development of a technique for quantifying the flow rate by the cooling rate of the cable, used in the framework of research using fiber-optic distributed borehole thermodebitometry. In addition to reaching quantitative indicators of well operation, discharge (flow rate), the technique provides comparative efficiency in the process of conducting research and in interpreting data carried out through the application of an experimental equation. Laboratory tests were performed using a well simulator installation using water and oil equivalent – diesel fuel. An experimental equation has been obtained, tested for the interpretation of research data in an operating well with the presence of an oil-water contact (OWC) directly in the research interval.
