Managing tops

GeoSyn includes four default lists for tops:

• Generic, which are tops listed in the imported LAS log files.

• AccuMap System Tops, which are always loaded from your local AccuMap database when you create a new model or launch an existing one. information for these tops may change following AccuMap data loads.

• AccuMap User Tops, which are always loaded from your local AccuMap user tops database when you create a new model or launch an existing one. Information for these tops changes based on changes you make.

• GeoSyn 2D Tops. Only tops that appear in the GeoSyn 2D Tops list can be used for correlation. During a well log import, GeoSyn automatically creates andpopulates this list. When importing GeoSyn 1D .syn files, the GeoSyn 2D Tops list is populated from the generic tops list associated with the LAS file. Using the Top Properties dialog box, you can update this list by copying tops from other lists.

You can create an unlimited number of tops lists with customized depths, copy tops amongst lists, and delete individual tops in lists. You can't delete the four default lists above, but you can delete the tops within.
