“…Stratal slicing has received much attention (e.g., Zeng, 2010Zeng, , 2013. De Groot et al (2010) indicate that, by greatly increasing the number of mapped horizons, one may achieve profound improvements in seismic interpretation. Some encouraging works include the phase-unwrapping approach (Stark, 2004), the dip-driven approach (de Groot et al, 2006), the predictive painting method (Fomel, 2010), and the global optimization algorithm (Hoyes and Cheret, 2011).…”

“…The model-driven mode is a way of slicing the seismic data relative to the framework horizons. The next stage in the workflow is to create a Wheeler diagram through 3D automated Wheeler Transformation [46]. Through Wheeler Transformation, the seismic data and attribute volumes were flattened in 3D along the auto-tracked horizons while at the same time, honoring the erosional events and non-depositional hiatuses [10].…”

Abstract:This study was carried out in the Pliocene interval of the southern North Sea F3 Block in the Netherlands. This research paper demonstrates how an integrated interpretation of geological information using seismic attributes, sequence stratigraphic interpretation and Wheeler transformation methods allow for the accurate interpretation of the depositional environment of a basin, as well as locating seismic geomorphological features. The methodology adopted here is to generate a 3D dip-steered HorizonCube followed by chronostratigraphic analysis, 3D Wheeler transformation, and system tract interpretation. A dip-steered seismic attribute (similarity, dip, and curvature) was performed on each stratigraphic surface of interest and the isopach maps were generated for each stratigraphic surface to help identify the maximum deposition. The results of this study show that the similarity attribute is able to identify distinct stratigraphic features such as sand-waves and deep marine meandering channels. However, its lateral continuity is poorly understood, as the similarity attribute does not take into account the true geological dip and curvature of the surfaces. Structural features such as faults are not easily recognizable due to these reasons. However, the dip-apparent attributes are found to be very useful in identifying both the structural and stratigraphic features. The seismic dip map is then improved by rotating the dip measurements to user-defined azimuths. Such optimization has revealed the structural and stratigraphic features that are not clearly evident on the similarity and curvature attributes. The maximum curvature attribute is found to be useful in delineating faults and predicting the orientation and distribution of fractures and also in subtle structural features.

“…To extract detailed stratigraphic information, more horizons are needed, which can only be done practically using a new generation of auto-tracking algorithms. One of these algorithms is the dip-steered auto-tracker of the HorizonCube method (de Groot et al 2010). The method starts by computing a dip/azimuth volume -called a SteeringCubefrom 2D/3D seismic data.…”

The conventional Wheeler diagram aids the construction of a spatiotemporal framework of strata. The diagrams are created manually by studying outcrops, wells, or seismic data. For the latter case, automated methods now exist, which support the construction of 2D, as well as 3D Wheeler diagrams. Seismic data contains information in three dimensions, X, Y and Z, where 'Z' is either two-way time or depth. Seismic horizons are correlated surfaces that often follow geological time lines. In this case, a set of interpreted seismic horizons contains information in four dimensions (X, Y, Z, and Geological Time). In the mapping from the structural domain to Wheeler space, information about Z (thickness) is lost. This means that one dimension is missing in the conventional Wheeler diagram. This paper describes a method to add information from the Z dimension to the Wheeler domain. It is done by computing stratigraphic thicknesses per sequence stratigraphic unit and displaying these as colour-coded overlays in the Wheeler domain. Thus displayed, thickness variations help in understanding changes in accommodation, sedimentation rate, and depositional trends. 3D Wheeler displays with colour-coded thickness information are referred to as 4D Wheeler diagrams. In this article, the method is described and applied to a case study from the southern North Sea.
