Processing and interpretation main knowledge-intensive work stages with source field seismic materials that allow for obtaining a reliable geological and geophysical model of our subsurface resources as the basis for oil and gas fields successful operation.

Processing of field seismic data in 2D, 3D modifications, high-resolution seismology (3C) aimed at mapping oil-bearing targets in seismic and geological conditions of various complexity based on Geovation (CGG) and Omega (Schlumberger) software.

Main processing stages:

• Compensation of weathering and near-surface effects by calculating and using primary and static corrections based on the method of refraction waves and tomographic approach.
• Data processing with amplitude restoration and preservation in time and space with inhomogeneities compensation by surface-coordinated procedures.
• Deconvolution and increase of seismic recording resolution, restoration of true shape and phase of the seismic signal.
• Multi-stage correction of static and kinematic modifications, optimization of summing phase synchronism.
• Separation and suppression of regular and random waves-interference with signal/noise ratio increase.
• Multidimensional regularization of data in space by distance and azimuths.
• Time and depth pre-stack migrations, depth-velocity model building.
• Data post-processing aimed at increasing the section resolution and sensitivity, bringing surveys to uniform appearance of the seismic signal and its phase.
