I am doing a project using well data. I have a master file that I am to update with production data. I know that I can use joins/relates to do this however, I am having some issues. 

  • My base layer (the one I am trying to update) has 19426 wells in the layer. 
  • My matching file (the one I am trying to use to update the base file) has 4012 wells in the layer. 
  • When I do the join, it verifies the join with no errors, however it is saying that I have 6985 matching objects in the files after the join. How can this be possible if there are only 4012 objects to be had?

Any advice/help would be greatly appreciated!
