This paper presents the results of analyzing the capabilities of well thermometry for the purposes of quantitative assessment of unproductive injection by hydraulic fracturing fractures and leaky borehole space. It is found that during formation of fractures of hydraulic fracturing, which occur at high repressions in injection wells, the informativeness of thermometry is significantly reduced due to formation cooling in the zone of fracture ends. However, both fracture half-length and reservoir permeability effect the temperature. Thus, more highly permeable formations transport cooled fluid from the fracture ends to the bottomhole zone faster. The established fact is a prerequisite for the development of a program of multi-cycle well tests, which allow to successfully establish the fact of unproductive injection in the formation, as well as to quantify the fraction of overflows. The paper also presents the results of a comprehensive analysis of non-productive injection in one of the fields of the Republic of Tatarstan. The analysis is based on production logging and pressure transient analysis, as well as methods investigating the interwell space. In addition, the research program is compiled on the basis of the analysis of informativeness of well thermometry under conditions of different types of non-productive injection, conducted on the basis of thermobaric modeling.
