The oil and gas production complex plays a leading role in the economy of the Republic of Kazakhstan, the development of which is associated with the exploration, development and exploitation of not only new, but also mature oil and gas fields. In recent years, the country's large and well-known oil and gas fields have entered the last stage of development, which is accompanied by water cut, deterioration of collector properties and reduction of production rates. One such field is Uzen. Under these conditions it is advisable to create a unified system for interpretation of well logging data, which is based on a reliable petrophysical model of the field. The purpose of the research shown in this article is to test the developed methodology for the integrated interpretation of logging data for complex reservoir strata in the Uzen field. Complex reservoirs are defined as those with a layered texture, irregular lithology and a complex void space structure. This approach makes it possible to develop cost-effective strategies to maximise field returns while minimising production and economic risks. This paper focuses on the results of testing a new methodology for interpreting logging data in order to produce the most reliable estimation parameters.
