The GEOLAB software is designed for high-performance processing of 2D and 3D seismic data, from input of raw data to computing the true-amplitude seismic depth sections (cubes). The software can be applied in data processing centers of service companies and service departments of oil and gas companies, as well as for research and development of new technologies and training of specialists in research centers and universities.

The basic functionalities are as follows: 

I. Input of raw field or marine data, geometry assignment 

- Traces in all popular formats 

- Information about the acquisition geometry in formats SPS and P1/90

- Processing of data with up to 25 microsecond sampling rate (Nyquist frequency 20kHz)

II. Analysis of kinematical characteristics with refined moveout description 

- Hyperbolical approximation 2D

- Hyperbolical approximation 3D

- Polynomial of arbitrary power 

- VTI

- Converted PS waves 

III. Random and coherent noise attenuation with adaptive operators adjusted using the refined moveout description

- F-X/F-X-Y deconvolution

- Median filter in the frequency domain to attenuate the coherent noise including the surface waves

- Pre-stack fan filter based on the Radon transform with no signal distortion and no NMO stretch: preparation of the gathers for dynamic AVO analysis

- Prediction of multiple waves with or without the velocity-depth model 

- Adaptive subtraction of coherent noise (including multiple waves) with the help of the multichannel Wiener filter 

- F set of tools for broadband signal processing: attenuation of ghost waves. Optimization procedure for the free surface reflection coefficient estimation and the ghost reflection delay. Attenuation of both the source-side and the receiver-side ghosts. Arbitrary configuration of the towed streamer. 

- Polarization filter for separation of monotype and converted waves on 2D and 3D data .

IV. Correction for near-surface inhomogeneities 

- Application of a priori static shifts 

- Automatic correction of short-period static shifts. Control of model consistency, refinement and edition of shifts, original method for solution of the system of linear equations 

- Automatic correction of long-period static shifts. Accounting for available a priori information, correction of the shifts in order to satisfy the model of static shifts 

- Wavefield redatuming to a specified depth level with an integral operator 

V. Signal processing 

- Robust surface-consistent correction of amplitudes 

- Tools for adaptive estimation and correction of the amplitude and phase wavelet spectra 

- Adaptive signature deconvolution that enables simultaneous adaptation both to the theoretical signature and the input gathers 

- Estimation and correction of the frequency-dependent absorption (inverse Q-filtering)

- Elimination of non-linear distortions in Vibroseis, use of harmonics as signal to broaden the signal spectrum 

- Combining the multifrequency data 

VI. RMS velocity model building and pre-stack time migration 

- Isotropic approximation 

- VTI and HTI

- Converted PS-waves 

VII. Construction of the velocity-depth model and pre-stack depth migration 

- Construction of the velocity-depth model using the migration velocity analysis hybrid-grid tomography and full waveform inversion (FWI)

- Various tools for depth imaging (seismic migration): Kirchhoff method, wavefield extrapolation in the frequency domain, taking into account the lateral and vertical velocity gradient (SSF, FFD OW WEM), in the reverse time. 

VIII. Built-in modules for seismic modelling 

- Ray-theoretical approximation

- Finite0difference method 

IX. Efficient use of parallel computing systems to speed up processing 

X. Extensibility and integration with other processing and interpretation packages
