High Resolution Seismic

The interpretation of seismic data using a 2D- sections and 3D- cubes of AI and RC is implemented with the vertical resolution that equals to the quantization step of the seismic recording time. In comparison with traditional recordings of seismic wave field, the resolution of AI and RC of 2D- sections and 3D- cubes is overall increased, i.e. the results of inversion (RC and AI) are comparable with the logging data.

    Concurrently, the practical vertical resolution of the terrigenous section is 3-4 meters, and the vertical resolution of the carbonate section is 5.5-6.5 m (sample rate is Δt = 0.002 c and the velocity of elastic waves propagation in terrigenous deposits is V = 3000-4000 m/s, while in carbonate deposits V = 5500-6500 m/s). In a first approximation, the results of these structural models allow evaluating the pattern of potential reservoirs in the studied sediments. Moreover, the major structural elements of investigated model allow evaluating the tectonic composition of the structural zone.
