Merge of two seismic AVO inversions: Montney example
This case study showcases seismic data challenges caused by surface conditions that significantly affected the quality of the 3D seismic survey. Given the large spatial variations in frequency and amplitudes observed in the seismic data, a different methodology was applied to overcome these challenges. It consisted of treating the quantitative interpretation study as two separate inversions. Each subarea was analyzed individually rather than hampering the quality of one side of the study to match the other one with substantially lower amplitudes and frequencies. The final inversion results were seamlessly merged using a frequency-based mask approach and workflow. The combination of two seismic inversion volumes seemed to be an acceptable alternative when dealing with strong spatial differences in seismic data that can be easily identified.
