The main procedures completed during the interpretation of seismic data, are:

1. Justification of stratigraphic control of reflecting horizons:

2. Detailed correlation of reflecting horizons: 3. Definition and tracking of tectonic disturbances in the joint analysis:

  • seismic section;
  • seismic attribute maps;
  • map of the first and second derivatives of surfaces;
  • map of curvature stretch and contour;
  • imap of forms;

4. Mapping isochrons:

  • map damping;
  • Map editing;
  • analysis of maps and their systems in a three-dimensional image;

5. A valid choice of velocity model and the implementation of structural models based on it:

  • calculation of vertical velocity spectra;
  • calculation of horizontal velocity spectra;
  • accuracy analysis of deep-velocity model design;
  • calculation of interval and average velocities for all target horizons;

6. Design and analysis of structural maps of stratigraphic surfaces in target layers and key horizons. Evaluation of reliability of structural models with:

  • estimation method of structural imaging errors by comparing with the data of drilling wells that are not included in the process of constructing the structural maps (validation method);
  • applying the key folds;
  • on the basis of mathematical models of the tectonic evolution history of the stratigraphic intervals in the section;

7. Seismic Inversion:

  • calculation of acoustic impedance section;
  • reconstruction of an effective model of the structure by method of simulation annealing;
  • AVO-elastic inversion that is based on the summation of various angles of incidence (prediction in the sections Vp, Vs, P);
