Batch Gridding

Map: Contours > Batch Gridding...

This operation allows Petra users to select and run multiple grids in the background.

Requirements

Map: Contours > Create Grid... Running multiple grids in batch mode requires that selected grids be saved with the following options:

·Auto Load/Save template with grid (Data tab)

·Create Grid Control Template (Miscellaneous tab)

Note: These options are selected by default when creating grids.

Control points

One of the options on the Create a Grid dialog Data tab is an option to "Include Control Points".  Control points are data points not tied to a particular well and can come from a wide variety of sources including seismic data, topographic surveys, or from legacy computer-generated grids. Control points are stored in various files read by the map and are included when a grid is used to create a contour. When multiple grids are run in batch mode maps are not referenced so any control points that have been added or changed after a grid was created are not included in the contour.

Important: Before running a batch list, always re-create grids that include control points modified after the grid was created.  Otherwise, new or modified control point data will not be included in the new contour.

Batch Grid list

Map: Contours > Batch Gridding... > Create Batch Gridding List...

A grid batch list instructs Petra which grids are run and in what order. This list is saved in the projects PARMS directory with a file extension of .BGL.

To create a Batch Grid list:

1.Open the map module.

2.Select, Map:Contours > Batch Gridding... > Create Batch Gridding List...

3.Use the dialogs controls (Open, Add, Remove or Clear) to create or edit existing grid list.

4.When done, click Save to name list and save to project Parms directory.

To run a Batch Grid list:

1.Open the map module.

2.Select, Contours > Batch Gridding... > Run Batch Gridding...

3.Select grid list to run and click Open. If asked to verify click OK.

Note: While the batch list is being executed the icon will be displayed on the task bar. Clicking on the icon opens a status dialog where you can monitor the operations progress.
