Finite Offset (FO) Stacking and Regularization

2D/3D Common Reflection Point (CRP) Regularization

The 2D/3D CRP Regularization technology is based on Common-reflection-point (CRP) Trajectories. This approach ensures that only the amplitudes related to the same reflection point are considered on the regularization process, avoiding reflection-point dispersal on dipping reflectors.

  • Based on CRP trajectories.
  • Enhancement of events.
  • Dataset regularization and interpolation.

The 2D/3D CRP Spreading technology is based on Common-reflection-point (CRP) Trajectories allows for reflection enhancement in prestack domain.

  • Based on CRP trajectories.
  • Noise attenuation.
  • Enhancement of events.
  • Correct conflicting dips.

ZO Stacking

Stretch-Free Stacking

The Stretch-free Stacking technology allows for stretch-free moveout corrections that can be applied to any traveltime approximation. This technique can be incorporated into any seismic-processing sequences since it requires no changes in the estimation of traveltime parameters. The Stretch-free moveout correction is performed on a separate procedure where the required stretch-free parameters are computed automatically, considering the previously estimated moveout parameters.

  • Elimination of moveout correction stretching factor.
  • Applicable to any traveltime approximation.
  • Can be incorporated into any seismic-processing sequence.

2D/3D Common Reflection Surface (CRS) Stacking

The 2D/3D CRS Stacking is a multiparametric traveltime stacking for reflections. The Common-Reflection-Surface (CRS) traveltime makes full use of redundancy available in the data, once it considers both midpoint and offset apertures around the central point, providing an enhancement on the signal to noise ratio. Furthermore, parameter guides ensure geological consistency and estimation convergence during the estimation of CRS parameters.

  • Full use of redundancy available in the data.
  • Parameter guides that ensures geological consistency and estimation convergence.
  • Global estimation of parameters through Differential Evolution (DE).

2D/3D Double Square Root (DSR) Stacking

The 2D/3D DSR Stacking performs the full stacking, in prestack domain, of diffractions considering the Double Square Root (DSR) moveout.

  • Multiparametric traveltime stacking for diffractions in prestack domain.
  • Superior approximation for diffraction events in prestack domain.
  • Global estimation of parameters through Differential Evolution (DE).

2D/3D Double Square Root (DSR) Spreading

The 2D/3D DSR Spreading technology allows the enhancement of diffractions. The stacking process uses a DSR diffraction traveltime, in prestack domain The spreading procedure has a similar structure as the ones used in Kirchhoff migration. The better-resolved diffractions can be used to determine fault-planes, pinch-outs, discontinuities and perform quality control for time/depth migration, providing update migration velocity models.

  • Enhancement of diffractions.
  • Determine fault-planes, pinch-outs, discontinuities.
  • Perform quality control for time/depth migration.
