Grid Using a New or Existing Polygon

From the Map Menu bar, select Grid | New Grid Using Polygon to display a submenu of options. from this sub menu, you have the following options:

New Polygon - Inside - Draw a new polygon on your map and create a new grid inside those parameters.
New Polygon - Outside - Draw a new polygon on your map and create a new grid outside those parameters.
Existing Polygon - Inside - Use an existing polygon to create a new grid inside its parameters.
Existing Polygon - Outside - Use an existing polygon to create a new grid outside of its parameters.

Select the option that you want, and the Create Grid With Polygon dialog box opens. Use this dialog box to select one or more horizons to grid. All output grids will use the same gridding method and parameters. Collapsed View image

Data is only available for gridding if it is associated with a horizon. To grid well information, such as depth and velocity, you must first associate the well top with a horizon. Read more.

This dialog box has the following options:

Select Input Data to Grid - This section enables you to select what attribute you want to grid with. You can select from Time, Amplitude, Average Velocity, Interval Velocity, and Depth.
Select Horizon Time Values to Grid - This section lists information about each horizon or fault, including the name, the type, if the horizon or fault is set to grid, the name of the horizon or fault as it will appear on your grid, and if the horizon or fault has been gridded before. If you want to grid a horizon or fault, double-click to select its check box under the Select column. If you want to change how a horizon or fault appears on your grid, double-click its name in the Name column, and type in a new name. If a horizon or fault was gridded before, then in the Gridded Before column it will say Yes. Double-click the word Yes to view the that horizon or fault's gridding history. If you selected Amplitude from the Attribute list as your input data, you can also choose how you want to treat zero amplitudes from the Treat Zero Amplitudes As list.
The title of this section will change depending on which data type you select from the Attribute list.
Select Source(s) of Data Values to Grid - Select data points for gridding. To include or exclude individual 2D seismic lines, 3D seismic areas, wells, or points, each section has its own Selection list . From these lists, ProductName provides you with the option to select all, some, or none of the items listed in the corresponding section.
