Abstract

The article reviews the results of the next re-interpretation of geological and geophysical material of Airakty gas condensate field located in Zhambyl region of Kazakhstan. Despite rather good prospects of oil and gas bearing of the region, quite a long period of geological and exploratory research, and discovered and developed fields, the study is extremely low, and the efficiency of geological and exploratory works here remains low. Therefore, the resource base for gas production remains insufficient to supply the region. Therefore, an attempt was made to examine the structure and oil and gas content of one field in this region from the point of view of non-anticlinal traps (NAT). This provides a new insight into the internal structure of the field and allows to clarify its geological structure and adjust the prospecting methodology in the direction of NAT deposits. The applied technology of re-interpretation of geological and geophysical material by approbation of neural training algorithms on the basis of new well data, synchronous prestack inversion (which is currently actively used in the exploration industry as part of the standard interpretation graph) allowed to take a new look at the peculiarities of the internal structure of rocks composing the productive part of the section, to highlight, in particular, isometric "bodies", which have been interpreted as incised river systems, e.g., isometric "bodies"
