Description:

 is a click on the screen edit.

 contains the log curve you want to edit > Change Default Well #5, select the
 well from the List or from a basemap.

 Graphic Edit:

 2.) Select Log Preperation #2 > Edit Log #1 > Graphic Edit #1 

 3.) Choose the edit function by entering > Change edit Function #3 > Invalidate
 (NIL) #3. By choosing 'Invaldate (NIL) this allows you to edit a gap and fill
 that gap with (NIL) values (-999.25).

 4.) Choose the curve or curves you want to edit > Choose Curve Set #1 >
 restore/edit curves #4 to display them to the screen.

 5.) Click MB1 to begin the edit, then click MB1 at the begin and end of the
 edit zone, MB3 to break, for multiple edits, and MB3 to exit the edit.

 6.) To apply the corrections choose > Apply Correction #6

 and exit > save data > enter description
