Surfaces

ResInsight is capable of mapping properties and simulation results onto 3D surfaces imported from GOCAD and Petrel as specified below.

Import and appearance of surfaces

3D surfaces from GOCAD and Petrel are imported into ResInsight by the menu option File->Import->Import Surfaces in the 3D Main Window.

Surface file formats are described in Surface Data

Imported surfaces are listed under the entry in the Project Tree. You can click on a surface to change i.e. the name or color of the surface, or change the file to read the surface data from.

You can also change the depth of the surface by adding a depth offset (positive or negative). This could be used i.e. to import the same surface file multiple times and assign each instance of the surface a separate depth offset. When a depth offset is set, the offset value will be shown as part of the surface name in the project tree.

Using folders

To make it easier to organize the surfaces you import into your project, ResInsight supports creating surface folders in the project tree. To create a new folder, right-click on the top level Surfaces folder in the project tree and choose Add Folder.

Surface Results

Per default, ResInsight maps current Cell Result on a given surface. If another result is to be displayed, specify the result under Surface Results as shown below.

Clicking a surface of a View in the Project Tree activates the Property Editor for allowing view settings as shown below.

To change result displayed on the surface, please specify the desired result in the Result Reference section of the Property Editor.

Reloading Surfaces

If you have modified a surface file using an external program, you can easily load the changes into ResInsight by using the reload surface feature. Bring up the right-click menu for the surface you want to reload and choose Reload. The views will automatically update with the new data (could take a few seconds).

Create a copy

You can easily create a copy of an existing surface by choosing Create Copy in the surface right-click menu. A new, identical surface will show up at the same level in the project tree. You can now give it a new name, change depth offset etc.

Grid Case Surfaces

In addition to importing surfaces from file, ResInsight can also generate grid case surfaces. You do that by bringing up the right-click menu for the project tree entry and choose Create Grid Case Surfaces.

A grid case surface has the same properties as a surface imported from file, but instead of choosing which file the data should come from, you choose a source case, a slice direction and a slice index. The slice direction and index will be added to the surface name shown in the project tree.

Depth Surfaces

A flat surface at a specified depth can be created from the right-click menu and select Create Depth Surface. A transparent surface is created, and color and transparency can be adjusted.

Exporting Surfaces

ResInsight can export surfaces to the GOCAD TSurf file format. Grid case surfaces can additionally be exported to Petrel Surface PTL format. Use the right-click menu for the surface you want to export and choose the export format you want to use. A file selection window will show up allowing you to choose where you want to save the exported data.
