In the context of low-permeable reservoirs development, the ports efficiency evaluation during multi-stage hydraulic fracturing in horizontal wells is an urgent task. One of the methods for assessing the inflow profile along a horizontal wellbore is tracer analysis with the placement of several types of tracers in the intervals of hydraulic fracturing ports (stages). This paper describes the steps for creating a hydrodynamic model in the RN-KIM enterprise software package and model matching to the results of tracer analysis, where several types of tracer were injected during each stage of hydraulic fracturing. Preliminary estimates of reservoir and well completion parameters are presented by decline analysis in the RN-VEGA enterprise software package for well testing interpretation. The results obtained from the decline analysis were used as an initial approximation for matching of the hydrodynamic model to the curves of changes of the concentration of the carried tracer (tracer fluid) for each stage of hydraulic fracturing. This approach made it possible to quickly match the hydrodynamic model to the well dynamic operation data. The tracer concentration curves for each hydraulic fracturing stage were used to estimate the individual parameters of each fracture. The results of these studies can be used to assess the feasibility of performing selective well interventions in individual wells and planning them in order to increase the well productivity.
