Abstract: A "Flogrid" Simulation Gridding Program is disclosed which includes a Flogrid "structured gridder". Input data is loaded into a Flogrid reservoir data store. The results generated by the reservoir data store are provided to the Flogrid reservoir framework. The reservoir framework is comprised of a structural model and a property model. The structural model will construct 3D structural models and the property model will create and edit properties. A Flogrid upgridder enables the user to group layers within a fine scale model into coarse layers, The results generated by the property model are input to the Flogrid "structured gridder" of this invention. The Flogrid "structured gridder" includes a "structured areal gridder" and a "block gridder". The "structured areal gridder" will build an "areal grid" on an uppermost horizon of an earth formation by performing the following steps: (1) building a boundary enclosing one or more fault intersection lines on the horizon, and building a triangulation that absorbs the boundary and the faults; (2) building a vector field on the triangulation; (3) building a web of control lines and additional lines inside the boundary which have a direction that corresponds to the direction of the vector field on the triangulation, thereby producing an "areal grid"; and (4) post-processing the "areal grid" so that the control lines and additional lines are equi-spaced or smoothly distributed.  The "block gridder" of the "structured gridder" will drop "coordinate lines" down from the nodes of the "areal grid" to complete the construction of a three dimensional "structured grid".  The "structured gridder" provides the "structured grid" to a Flogrid upscaler which samples specified properties within each grid block of the structured grid and performs appropriate averaging to assign a representative grid block property to each grid block of the structured grid, thereby producing a "simulation grid". A reservoir simulator will receive the "simulation grid" and generate a set of "simulation results" which are displayed on a 3D Viewer for observation by a workstation operator.
