An analysis was carried out to determine if 3D seismic could be used to build a subsurface model, revealing in detail where gas escape chimneys feed shallow gas accumulations, allowing the shallow hazards to not only be mapped accurately and risk reduced, but also indicate the relationship to the target reservoir itself. The method used techniques that exploited the potential and rich data content of the medium, to increase the speed and accuracy of the analysis, but retaining interpretation subjectivity.
