“…This characteristic is very significant as it incorporates unconformities automatically and reveals depositional hiatuses in the Wheeler domain. In this study, the Continuous HorizonCube was initially created and later converted into a Truncated HorizonCube by following the methodology used by Qayyum et al [11], de Bruin et al [10,44], and Brouwer et al [45] to map major bounding surfaces. Intermediate horizons were auto-tracked with sub-sample accuracy.…”

“…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]. By integrating the Wheeler domain and structural domain, we can make a system tract interpretation on multiple 2D sections which will give a full or complete 3D understanding of the system tracts.…”

“…Recent software developments, particularly through open-source software such as OpendTect, have enabled researchers to study time attributes of seismic stratigraphic surfaces within the chronostratigraphic framework by using 3D Wheeler Transformation [7,8] and recently 4D Wheeler Transformation [9]. Through 3D Wheeler Transformation, seismic data, as well as attribute volumes, are flattened in 3D space [7] along the auto-tracked horizons while at the same time honoring erosional events and non-depositional hiatuses [10]. Recently, a fourth dimension was introduced [11] which integrated stratigraphic thickness per stratigraphic unit into the 4D Wheeler diagram.…”

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.

“…Using both the enhanced seismic data and the 3D horizons framework it is possible to interpret the paleo-geomorphology of the entire seismic volume and identify stratigraphic features such as erosional events, non-depositional hiatuses [35], submarine channels, debris flows and most importantly turbidites. Figure 12 illustrates the enhanced seismic image and the corresponding 3D horizons framework for an Inline of the seismic survey.…”

Building geological models (integrating stratigraphic, structural and paleo-environmental 3D models) that allow the interpretation of sand bodies deposited by turbidity currents along submarine canyons or channels, is one of the most useful tools used by geoscientists for the definition of new drilling opportunities in both exploration and development phases. In this context, the integration of methodologies such as sequence stratigraphyand seismic attributes, together with well-log and core information, outline the basis for the interpretation of sand-body lithostratigraphy and chronostratigraphy. Similarly, these models allow the interpreter to reconstruct the depositional environment and deformation history of a sedimentary basin [1]. Based on a series of chronostratigraphic stages, this paper proposes a 3D model for the sedimentation history of the Banquereau Formation.This model is based on the integration of seismic stratigraphy, seismic attribute interpretation and well-log analysis. Also, a set of system tracts and corresponding transgression and regression phases were identified for the sedimentary interval of interest. The available dataset provided the information to identify the geometry and changes in the sedimentation patterns of the stratigraphic sequences from the Tertiary to the present, thus defining a 3D model of the sedimentological and structural architecture of this interval. Last but not least, theresulting 3D stratigraphic model made possible the identification and description of an amalgamated channel complex filling a submarine canyon associated with a fluvio-deltaic setting. This sort of analysis might be used as an analog for similar reservoirs, providing key insights and vital information for decision making.

“…Numerous chronostratigraphic events (figure 2) are auto-tracked per sequence bounded by (conventionally) mapped horizons. In order to create a 3D chronostratigraphic diagram or 'Wheeler transform' (figure 1), seismic data and (meta-) attribute volumes are flattened in 3D whereby erosional events and non-depositional hiatuses are honored (de Bruin et al, 2006). Furthermore, sequences are subdivided into systems tracts (figure 4), and the stratigraphic surfaces are analyzed simultaneously in both the structural and Wheeler domain.…”

Recent software developments (OpendTect SSIS) enable us to study the time attributes of seismic stratigraphic surfaces within a chronostratigraphic framework by means of Wheeler transformation of seismic data. Studying stratigraphic surfaces in the structural and the Wheeler domain enhances our understanding of time attributes of these surfaces. The maximum flooding surface marks the end of transgression and the onset of normal regression and is a highly isochronous event. The basal surface of forced regression corresponds to the seafloor at the onset of forced regression. This is a highly isochronous event that coincides with the start of erosion at the top of the high stand deposits and the formation of the subaerial unconformity. The subaerial unconformity is a highly diachronous event that starts at the onset of forced regression, when the basal surface of forced regression is formed and stops at the end of forced regression, which coincides with the correlative conformity. The correlative conformity corresponds with the end of forced regression and highly isochronous. The maximum regressive surface marks the end of normal regression and the onset of transgression. This surface is in our case moderately isochronous.
