description: In the oil industry and especially in oil wells, it is necessary to be able to carry out continuous production measurements in order to manage the well in the best possible way. This paper presents data analysis for a non-intrusive direct and scattered gamma ray method that measures the gas fraction variation in two-phase oil well production flows. The method is based on the classification of observation intervals for two-phase flow using statistical period estimations. The feature of informativeness estimates are obtained using the Kullback-Leibler divergence, which revealed the importance of the radiation source activity, the detector efficiency and also the role of scattered gamma to be able to identify the moments of free-gas absence in the production flow which greatly affects the measurements. Furthermore, the formula for estimating gas fraction present in the oil-gas flow is provided.
