[en] Studied were the regularities of heat flow distribution and its connection with radioactive anomalies in the area, placed on the prolongation of wing of exploited oil-gas field. Geologic surveying was carried out with the help of boreholes, with the depth up to 25 m and temperature measurements in hydrogeologic boreholes drilled before. Surveing results are presented as geologic-geothermal profiles and isothermal diagrams, plotted according to the results of temperature measurements at the depths of 3.10 and 25 m. Two geothermal anomalies connected with the geologic-structural peculiarities and with the increased radioactive element concentration are singled out. It confirms the possibility of using geothermal observations for a more precise deffinition of geologic-structural peculiarities of the areas under study and for estimation of radioactive anomalies found before
