“…Probably the most dominantly used geophysical data in geological models are reflection seismic data, either classically in the form of 2-D seismic sections, but increasingly also in the form of 3-D seismic cubes (Dorn, 1998;Jackson and Kane, 2012) and it can be argued that reflection seismic data sets provide the closest form of a direct "imaging" of the subsurface structures (Davies et al, 2004). Uncertainties in seismic data have been analyzed in numerous studies (e.g.…”

The Earth below ground is the subject of interest for many geophysical as well as geological investigations. Even though most practitioners would agree that all available information should be used in such an investigation, it is common practice that only a fraction of geological and geophysical information is used. We believe that some reasons for this omission are (a) an incomplete picture of available geological modeling methods, and (b) the problem of the perceived static picture of an inflexible geological representation in an image or geological model. With this work, we aim to contribute to the problem of subsurface interface detection through (a) the review of state-of-the-art geological modeling methods that allow the consideration of multiple aspects of geological realism in the form of observations, information and knowledge, cast in geometric representations of subsurface structures, and (b) concepts and methods to analyze, quantify, and communicate related uncertainties in these models. We introduce a formulation for geological model representation and interpolation and uncertainty analysis methods with the aim to clarify similarities and differences in the diverse set of approaches that developed in recent years. We hope that this chapter provides an entry point to recent developments in geological modeling methods, helps researchers in the field to better consider uncertainties, and supports the integration of geological observations and knowledge in geophysical interpretation, modeling and inverse approaches.

“…Some attributes have been widely used for specific fault 8 characterisation, such as dip, azimuth, curvature, semblance and structurally oriented filters (e.g. Bahorich and Farmer, 1995;Chopra et al, 2000;Jackson and Kane, 2012).…”

“…Dip and azimuth are respectively the angle below the horizontal and the azimuth of a vector along the reflector's dip direction; and curvature quantifies the deviation of reflectors from a plane based on local dip changes (e.g. Bahorich and Farmer, 1995;Chopra et al, 2000;Jackson and Kane, 2012). An alternative method is to compute the attributes directly from the seismic data without including horizon interpretation.…”
