Enrich 3D geological models through 2D seismic restoration
The Seismic Slicing plug-in enables a workflow where consistent interpretations of new conformable intermediate horizons can be simply added to 3D geological models (structural frameworks, pillar grids), without having to use isochores. To do so, the user just has to use Petrel’s 2D seismic restoration tool with the produced interpretation objects and simply interpret new horizons in a flat space.
Enable 2D seismic restoration with multi-z structures
Petrel’s seismic horizons are by nature single-valued and can hardly be used to represent multi-z objects that are however very common in models with thrust faults or more complex structures. With the Seismic Slicing plug-in, the produced horizon interpretation corresponding to a multi-z surface is a single interpretation object, which makes it usable by the 2D seismic restoration workflow.
Create a large amount of synthetic data in seconds
The Seismic Slicing plug-in is a very powerful tool to create various kinds of synthetic interpretation data from already built surfaces or geological models, thus avoiding to create manually “fake” interpretations. This is particularly handy for testing and validating workflows or processes that consume interpretation objects, like grid/mesh generation or geological model building algorithms.
Build sealed 2D geological models
Because the Seismic Slicing plug-in produces objects that are the exact intersection between 3D surface-like objects and planes, if two surfaces have geometrically perfect contacts, then their computed slices also have perfect contacts. That is why lines corresponding to slices built from 3D sealed geological models (structural frameworks, pillar grids) are already geometrically sealed 2D models.

Overview
The Seismic Slicing plug-in computes quickly the intersection of 3D surfaces (triangle meshes, regular surfaces) or 3D geological models (structural frameworks, pillar/structural grids) with planes defined by inlines or crosslines of a seismic cube. The resulting interpretation objects can be points, lines/polygons, fault interpretations, seismic horizons or multi-z interpretations.
Specifications
Sliced structural frameworks can be built with FGD, MPI or VBM algorithms.
Stair-stepped faults that may exist in 3D grids are ignored by the slicing processes.
The full resolution of the sliced objects is kept, no geometrical simplification involved.
When building lines/polygons or fault interpretations, the topology of the produced lines is similar to the one of the sliced objects, except for the fault interpretations built from geological models that are slightly processed to remove intersections with other faults and horizons, so that they become suitable for 2D seismic restoration.
Features
The user has the choice of creating or overwriting interpretation folders when running the processes. Objects can be sliced by a single plane or by multiple parallel planes. The surface slicing process supports multi-selection of objects. Produced seismic horizons are processed to be able to represent multi-z structures. Produced fault interpretations are not cut with other faults and horizons.
