@Terry53029 My understanding is that for working interests, you must use the higher of cost depletion or percentage depletion.  And, if you want to do accounting for owners of working interests, you need to keep workpapers to show your calculations and carryovers, per property.  There is software for that, but they don't quote the price online.  Which leads me to believe that it's expensive.
