Building faulted grids for a sedimentary basin including structural and stratigraphic interfaces

摘要

A method including: providing, in a computational space coordinate system, an initial, at least vertically structured, multidimensional grid that includes initial nodes that define grid cells (920); referencing a conformal mesh to identify a set of grid cells of the grid traversed by a fault (930); rasterizing the fault within the grid along the identified set of grid cells to split the grid along the rasterized fault into first side grid cells and second side grid cells (940); altering the grid by projecting nodes from the first side grid cells to a first side of the fault and projecting nodes from the second side grid cells to the second side of the fault (950); and transforming the altered grid to generate, in the real space coordinate system, a transformed grid (960).
