Geomage deploy proprietary geophysical software developed and tested on many projects from different geological and geophysical settings and conditions.

MULTIFOCUSING PROCESSING 2D / 3D

Substrata and Geomage provides most accurate seismic data processing services with its proprietary MultiFocusing Imaging technology. Geomage MultiFocusing© imaging used successfully all across the globe for wide spectrum of different geological/geophysical conditions/problems:

  • Data interpolation and regularization
  • Structural seismic imaging
  • Unconventional seismic
  • Sparse/low-fold seismic
  • Wide/Full-azimuth seismic

MULTIFOCUSING DATA ENHANCEMENT

In many situations, increasing SNR of pre-stack seismic traces is requested. Typi­cal examples are velocity model-building and pre-stack imaging. Wavefield parameters estimated by the Common Offset MultiFocusing (COMF) method can be used for pre-stack data enhancement, interpolation and regularization.

In this case application locally stacks prestack traces related to near offset/azimuth values along estimated COMF kinematics parameters. The fold and position of traces in the produced gathers can be defined by original geometry or regularized according to virtual acquisition pattern.

The result of the summation is assigned to the same surface location, offset, and source-receiver coordinates. Repeating this procedure for all desired points generates a new trace gathers that is called the COMF enhanced gather.
