| Popis: | R ecent research and surveys have recognised the applicability of conventional 3D seismic for pre-drilling shallow hazard analysis. Selvage et al., (2012) introduced a shallow hazard analysis framework to leverage the spatial bandwidth in 3D seismic for assessing shallow hazards. The proposed method is applicable for a variety of depositional settings ranging from shallow water to ultra deepwater conditions. The benefits of conducting shallow hazard analysis in 3D seismic data as opposed to 2D data include: increased spatial accuracy, the improved reliability of postand pre-stack amplitudes and enabling volume-based and amplitudeversus-angle (AVA) based attributes to be interpreted. 3D seismic data also allows global interpretation methods (i.e., methods that aim to generate fully interpreted volumes; see also de Groot et al., 2010; Hoyes and Cheret, 2011; Stark et al., 2013) to be applied in shallow hazard interpretation workflows. These techniques enable the ability to slice through volumes of seismic amplitudes and derived attributes along geologic timelines, thereby facilitating the recognition of depositional features and potential shallow hazards. This article will provide an overview of how one global interpretation method – the HorizonCube – can be applied in shallow geohazard interpretation. |
