                                                        By reading in an existing simulation data set, the user can display and visually
                                                        check where the well perforations have been completed and assigned, relative
                                                        to the grid and grid layers. The user can also visualize any local grid refinements
                                                        and the locations of the perforations within the refined area. Visually, the user
                                                        can adjust, modify, or add additional perforation information as required to
                                                        ensure that the simulation model best represents actual field events. Well logs
                                                        can be superimposed on the simulation grid to allow easy and accurate
