Seismic Data Conditioning
To ensure a successful QI study we offer a full suite of seismic data conditioning tools to improve the quality of the input seismic data. These include various noise suppression techniques and other processes to get the data into a state that is suitable for inversion. Our seismic conditioning algorithms and our QC products are developed in-house specifically for AVO inversion applications. All of our techniques pay particular attention to amplitude and wavelet shape preservation during conditioning.

Qeye's Seismic Warping
Seismic warping or alignment is an essential tool within the seismic quantitative interpretation workflow.
Applications include:
- angle stack warping suppresses seismic event misalignment originating from inaccurate velocity modeling or migration (Figure 1)
- 4D warping estimates time shifts that arise from velocity changes due to production and/or compaction (Figures 2 to 5)
- 4D warping suppresses lateral positioning errors associated with velocity changes and migration across structural features (Figure 4)
- 4D warping is essential to estimate the geomechanical effects within and around the reservoir arising from hydrocarbon production
Our warping algorithm has the following key features:
- 1D and 3D warping with optional geological dip constraints
- displacement cube is optimized both locally and globally
- amplitude preserving – making it suitable for AVO inversion
- the computed displacement field can be used as a constraint in the 4D inversion
