the results of a comprehensive interpretation of 3D seismic and well data within the contract area of LLP “Aman Munai” at the AkzharVostochny field are presented. Based on the results of acoustic logging in wells and on the basis of the performed time-to-depth conversion of seismic data, a model for the distribution of velocity parameters of the subsalt section is constructed, and patterns of changes in the velocity model in the “dome-basin” sections are studied. According to borehole data, correlation of uniform age deposits was performed. The maps of isochron and structural maps of the main subsalt horizons (P1, P1a, P2, P3), maps of the distribution of average reservoir velocities P1a-P2, maps of isochores and thicknesses were constructed. Based on the compiled map of the distribution of the velocity parameter P1a-P2 and the results of field operations, correlation dependencies were found that made it possible to build forecast maps of maximum productivity for the main production horizons of the field. Recommendations are given in the direction of further research aimed at identifying and studying traps of this type, and specific areas for setting up deep exploration and production drilling on the studied territory are indicated.
