Upgridding Utility

Before and After

Comparison of original and upgridded models.

Plug-in Overview

Having the right size grid is key to efficient runs of your simulator. The Upgridding Utility for Petrel allows you to group layers in a Petrel model into coarser layers for simulation, while preserving the flow characteristics of your model.

Specifications

• Viewing statistical average property as a model, per zone, or as a table
• Calculating variations between property layers represented on histograms or tables
• Upgridding layers by analyzing variations between them
• Upgridding both manually (step-by-step) and automatically for selected layers
• Calculating zone fractions and pasting into Petrel layering procedure

Features

The Upgridding Utility for Petrel merges fine-scale layers in a Petrel model into coarser layers using a variability-based method. Variability-based upgridding preserves simulation grid cell boundaries where there are big changes in a selected property of the geological grid, removing the boundaries between similar layers. The user can view the proposed changes to the layers before committing them to the model.
