Canadian County S29 11N 10W multiple wells

We have offers from multiple entities for the same mineral interests, however the offers relate to two different companies planning two different wells at two different depths. All of the depth clauses I have seen expire at the end of the primary term, which I assume means that you can’t execute two different leases at two different depths at the same time. Is it possible to do this? The wells are Midge and Gathers. I’ve never had this situation, so I’m not sure how to handle this. Thank you for any assistance.
