Local PEBI grid generation method for reverse faults
چکیده انگلیسی

•Local method of PEBI grid generation is proposed to address the reverse faults.•Locality of the method exhibits better adaptability to complex structures.•The use of background grid accelerates the search process of the algorithm.•The PEBI cells present good quality through the Centroidal Voronoi Tessellations.

The 2.5D PEBI (PErpendicular BIsector) grid, which is the projection or extrusion of the 2D PEBI gird, has advantages on practical reservoir modeling. However, to appropriately handle the geological features, especially the reverse faults in reservoir, remains a difficult problem. To address this issue, we propose a local PEBI grid generation method in this paper. By constructing the Voronoi cell of a seed based on the search of its neighboring seeds in a background grid, our method is demonstrated to be efficient and adaptable to reverse fault constraints. In addition, the vertical and horizontal well constraints are also tackled and the cell quality is improved through the Centroidal Voronoi Tessellations (CVT) principle. The results demonstrated that our method enables the formation of high-quality grids and guarantees the conformity to the geological features in reservoirs.
