Forecast for sediment facies zoningPz based on modern structural plan is not possible due to the fact that carbonate formationPz formed in other paleotectonic conditions

 

• AIM (multiwave seismic);
• PLAY (high-resolution seismic volume with a parametric sweep reflections);
• The method of the inverted hodograph - ish and marketplace implementation - 3D VSP (imaging medium in the vicinity of wells in selected waves of various types) ;
• Microseismic infrasound technology oil and gas exploration ANCHAR (low-frequency acoustic intelligence - information signal is noise microseismic emission of oil and gas deposits, the spectrum of the MS is in the infrasonic frequency range);
• SLBO (Seismic side-scan sonar) - using scattered seismic waves, designed to study the spatial (ZD) and space-time (4D) field of open fractures in geomedium
new technologies of seismic
Seismic side-scan sonar

Application of new technologies of seismic
provides for the introduction, development and improvement
advanced processing techniques

Forecast of the feasibility and effectiveness of multi-wave seismic data or use other technologies
must be based on modeling that suggests:

-analysis of information on the area and work area as a whole;
- geological model construction job site;
- seismogram calculation of longitudinal and converted waves;
- selection and optimization of the monitoring system;
- graph optimization process for a specific geological cross-section;
- Analysis of the results.


Successful implementation of the method of multiwave seismic exploration is bringing modifications converted waves in the middle to the same level as for the modification of the longitudinal waves in its present state

  • Prediction of the geological section of the upper part of the Paleozoic formations
    (forward-looking areas, looking at the contents of the SW) is based on:
  • study of the geological information on wells;
  • Reconstruction of sedimentation conditions;
  • attracting set of parameters:
    - seismic (structural plan, the dynamic, kinematic attributes; seismostratigraphic analysis, classification of the waveform);
    - non-seismic research results (magneto-gravity geoelectrical);
  • comparison of all identified promising targets
study of the geological information on wells Reconstruction of sedimentation conditions attracting set of parameters comparison of all identified promising targets
Based on the results of integrated interpretation
distribution forecast is made of the weathering crust

- identified zones of high fracture;
- mapped reef seismic facies;
identified zone dolomitization, characterized by
high-speed boundary according to the SEISMIC PROFILING,
