Log signatures may be displayed on plan views of the field. Scatter plots and scatter plot matrices may be constructed quickly and easily so that you can be sure of the quality of your correlation. Finally a suite of variogram analysis and modelling tools are available to operate on your raw data so that you can have confidence in your modelling. Regular A regular orthogonal grid in which the blocks are all the same size though the number of blocks in x, y and z can differ. Corner-Point A grid where the vertices of each cell are explicitly defined.
All grids support hierarchical local-grid refinement.
This support for multiple grids and grid types allows geologists to view the simulation grid and for all geoscientists to be aware of what may be happening to their models before, during and after the upgridding and upscaling of data to simulation scale grids. GEOCard provides a variety of grid-based deterministic modelling using Kriging techniques and a number of stochastic modelling algorithms such as indicator and Gaussian simulation. It may be viewed as a spreadsheet and can be manipulated using a powerful expression parser to create new attributes and compute volumetrics. The results of these simulations can be gridded into a geological grid or used as templates to control grid-based simulation and interpolation algorithms. To get the geological model into a reservoir simulator the geological grid often needs to be coarsened.
