The purpose of the work is analysis of the outputs of field tests to establish of operability of the cryogenic gravel-packed filters technology for hydrogeological wells, as well as for economic efficiency of proposed technology. Methodology and scientific approaches. For solution of considered tasks the integrated methods were used, including analysis and generalization of publications and patents, analytical and experimental studies. The scientific value of the work. The scientific basis of choice of effective parameters of cryogenic gravel-packed filters was created. Proposed technology can be used with fine-grained sands. The results usage. The proposed technology is intended for wells with complex conditions of drilling and completing. The application area of described technology is wells of various purposes with cryogenic gravel-packed filters at up to 200 m deep producing intervals, represented with fine-grained sands. The practical value. The cryogenic gravel-packed filters have been implemented at hydro-geological wells, drilled for a Joint stock company «Industrial and geological group «Dnieprohydrostroi». Originality/worthiness. The results of field tests related to a new gravel-packed filters technology were presented. The cost effectiveness of the tested technology was established.
