Our goal is to deliver the best geophysical service to Oil & Gas Companies, using ultimate technology and artisan’s dedication.

Depth Imaging  

The workflow used at DataSeismic allows several updates of the initial model of the velocity field, refining in each step this model and the use of multidimensional and multivolume data analysis and visualization help to obtain a superior delineation of geologic formation in complex areas.

Migration Algorithms

1. Kirchhoff Depth Migration

Kirchhoff methods are widely recognized as one of the most comprehensive and flexible methods of imaging prestack 3-D seismic data. Handles all processing challenges:


• Travel-times generation

• Most Energetic travel times

• Shortest Path travel times

• First Arrival travel times

• Anisotropic Curved Rays for PSTM

• Anisotropic VTI travel times

• Anisotropic TTI travel times

• Converted waves, OBC

• VSP geometry

• Targets, grid of targets, sparse target lines

• Gamma migration scans

• Diffraction Imaging

2. Fast Beam Migration

DataSeismic uses a super-efficient algorithm that is two orders of magnitude faster than the industry standard Kirchhoff depth migration. Fast Beam Migration images multipathing energy, a property that is typically associated with wave equation migration algorithms. The faster and more accurate imaging step allows for more iterations of velocity model building (50–100 iterations in lieu of the current 5–10.) A greater number of velocity updates enables the processing team to enhance the resolution and imaging of complex geologic structures. Improved velocity models in combination with FBM or wave equation imaging can provide much greater resolution and accuracy than that which can currently be obtained with standard imaging technology.

Grid based tomography supported by layers. Isotropic and anisotropic updates.



Velocity Model Building

Velocity Model Building is an essential component for accurate depth imaging. Using a wide range of velocity model building algorithms and workflows, we provide high resolution depth anisotropic velocity models:

1. Vertical and normal ray updates

2. Deregowski loop updates

3. Wide azimuth tomography using offset gathers produced by Kirchhoff or Fast Beam Migration (FBM)

4. Wide azimuth tomography using angle or extended gathers produced by Kirchhoff, Fast Beam, or wave-equation migration

5. Residual move-out gather-flattening and gather-fitting techniques
