Abstract
The work is aimed at generalization the existing methodological developments in the field of using 3D seismic data at the field development stage. As an example, practical examples are given for three objects with different geological conditions. Two objects confined to terrigenous sediment and one represented by carbonate rocks of Proterozoic age. Various methods of analysis of 3D seismic data are used, which include such popular areas as seismic facies analysis, spectral decomposition, analysis of the scattered component of the wave field, inversion, etc. As a result of the analysis of significant experience in the implementation of seismic and geological monitoring at objects with different geological structures, the main goals and sequence of such work are formed. Recommendations are given on the specific scope of work at each stage, methodological features of each stage are described.
