At regional and prospect stages, the seismic stratigraphic approach to seismic data interpretation and classic geological analysis methods are used.

The complex field geostatistical model creation process consists of the steps as follows:

  • Seismic data to geologic section calibration (see Fig. 4);

  • Selection of interpretative base (time section, pseudo-acoustic or AVO inversion sections, etc. – see Fig. 5), (Fig. 6 illustrates results of acoustic inversion);
  • Object localization in space
  • Target model creation (see Figs. 7, 8);
  • Seismic facial analysis (see Fig. 9);
  • Attribute analysis;
  • Searching for correlative or other relationships between seismic attributes and petrophysical properties of targets (see Figs. 10, 11, 12);
  • Predicting the reservoir parameters using seismic data (see Fig. 13);
  • Estimating reservoir parameter prediction accuracy (see Figs. 14 , 15 , 16;)
  • Creating the reticular 3D target models.
