Associate Horizons

Well tops names are associated with WinPICS horizon names. When you post or grid data for a horizon, WinPICS makes the well data for associated tops names available.

The associations are created while Importing Well TOPS, but they may be created while entering tops manually or edited at any time. Follow these steps:

  1. On the Application Toolbar select |Well Database.
  2. From the well list, select the wells you want to work with. The changes you make will apply to only those wells which you have selected.
  3. Click Tops Functions | Associate Horizons.

Tops List

The green boxes in the Import column indicate associations made during the import process or created when manually entering tops for individual wells.

The TOPS Name column lists the tops names found for the selected wells.

The X-Ref Horz Name lists current cross references between tops names and horizon names. Changes can be made by selecting the appropriate Horz X-Ref buttons.
