Abstract. The application of distributed temperature sensor technology has proven successful in conducting temperature measurements in offshore boreholes. However, despite positive usage experience, the question of the accuracy of temperature measurements performed according to this methodology is still under discussion. The accuracy of the obtained temperature measurements is significantly influenced by the calibration process. A new approach to calibrating DTS data in offshore wells is proposed in this work. An example of temperature data obtained using the proposed calibration methodology is provided.

Keywords: wellbore thermometry, distributed temperature sensor method, calibration methodology
