A Domain Transformation process has been developed to remove all structural effects in three dimensions from 3D seismic volumes. This interpretation-guided process improves upon previous technologies (e.g., horizon slicing and proportional slicing) by removing the full range of possible sources of structural deformation, regardless of how structural elements may be combined in a given seismic volume. By removing fault displacement in 3D, stratal volumes are created where there are no gaps associated with faults, as is the case for the vertical trace shifting and vertical trace interpolation of previous techniques. The Domain Transform not only allows substantially improved imaging of depositional systems for rapid identification and interpretation, it also enables a number of new workflows that could improve the efficiency and effectiveness of 3D seismic exploration and development. These workflows provide a unique way in which to integrate structural and stratigraphic interpretation so that each step provides an opportunity to Q/C, correct and improve interpretation in the other steps.

True Volume interpretation is developed to move 3-D interpretation from tools that support viewing the data in 3-D and interpreting it in 2-D to tools that enable data interpretation in 3-D, improving subsurface understanding. The workflow begins with the identification of the type of geologic feature of interest followed by processing to create an attribute volume that optimizes the imaging and visualization of that type of feature in the volume. The Automated fault extraction (AFE) is used to create a fault probability volume from the edge stack volume. The final step in the structural workflow is horizon identification, and the resulting structural interpretation provides several attribute volumes and a structural interpretation along with the seismic volume. The distortions caused by the structural elements are removed from the volume, producing a stratal volume where every horizontal slice represents a paleo-depositional surface. Source

In a survey of Landmark, Paradigm, Schlumberger, and TerraSpark commercial products, the median number of parameters per volume process (such as attributes, or smoothing processes) was two (Figure 1a), with some volume processes having as many as 18 parameters. Each parameter used to control a volume process represents an added dimension to the parameter space of that process. With many parameters, evaluating that parameter space to find the best combination of parameters for a given data set can be quite time-consuming. Selecting the best parameter values can be daunting for an experienced user and an effective "barrier to entry" for a potential new user, causing them to not even try and instead move on to another type of technique. © 2011 Society of Exploration Geophysicists.
