“…The intersecting algorithm, which is described in more detail in (Frambati & Rodriguez-Martìnez, 2017), consists of an alternating propagation process that follows both the topology of the surface, represented as a triangulated surface, and the topology of the reservoir grid. This process requires a first step consisting of a "seeding" in which we find a first cell to start the search, complexity O(n log n), followed by an alternating propagation over the grid and the triangulated surface, complexity O(k), where n is the number of cells in the grid and k is the number of cell couples that represent the surface in the grid.…”

Current reservoir modeling workflows are very rigid, since any modification to the understanding of the underlying structural model often requires a complete regeneration of the reservoir grid, with the associated costs, delays and incompatibilities with past calculations. We propose a novel workflow for structural features modeling, allowing the introduction of faults and other structural and non-structural features in any kind of simulation grid without modifying it. A new tool, capable of implementing the proposed workflow, is presented along with several real-world case studies that prove the advantages of the new workflow.
