Importing directional surveys

You can import and modify a directional survey saved in ASCII, GeoGraphix, or Open Works format, or create one from scratch by typing measured depth, dip, and azimuth values.

If a well from the IHS Information Hub has a directional survey available and you're licensed to access directional surveys, you can save it to disk while downloading the log and then import it into GeoSyn. For details, see Related Topics below.

To import a directional survey:

1. In the depth page, right-click the well for which to import a directional survey and from the shortcut menu, select Well properties.

2. Beside the TVD corrected check box, click Import directional survey.
