The Bezymyannoye field is located in the eastern part of the Caspian depression, in the southwestern flank of a salt dome located on Zharkamys uplift. Prospects of oil and gas potential in this area are associated with the salt deposits of the Kenkiyak stage. The area under study can be considered one of the most perspective regions of Kazakhstan in increasing oil and gas production. Modern CDP seismic techniques provide solutions to structural and tectonic problems with high degree accuracy and reliability. However, the complexity of the geological structure and depth of surveying increases the inaccuracy of kinematic interpretation of seismic data up to a complete loss of data in target intervals, as evidenced by repeated facts of significant discrepancy between deep drilling data and seismic structures. The article highlights the most optimal choice and implementation of processing graphs based on reprocessing of 3D seismic data from a seismically and geologically complex area. Particular attention is paid to the structural interpretation, thus allowing clarifying the geological structure of Mesozoic rocks, Paleozoic productive and salt- bearing sediments in the area. The article recommended correlating productive horizons for further use in building a geological model. An additional study of the Upper-Permian structure is recommended for explorational drilling purposes.
