Application of well testing data to forecast the productivity of water intake well in the northern part of the Shaimsky oil and gas producing area

The search for the most watered intervals in the section of the Kurtamysh horizon is an urgent task for providing the population with drinking water. Well testing data were used for this purpose. The methodology of the work included interpretation of gamma logging curves, normalization of samples obtained under various measurement conditions. The boundary values of the double difference parameter of natural radioactivity are determined. The possibility of using this method to characterize the filtration properties of rocks is evaluated. Statistical processing of data on the operation of water intake wells was carried out. The closest correlations have been established for the flow rate and specific flow rate of wells with a double difference parameter of natural radioactivity. According to the interpretation of the curves of the gamma logging of wells, forecast maps of the most promising intervals of the captage of water intake wells are constructed. The results of the study have methodological and applied significance, and can be used in the design of groundwater intakes.
