Most companies (in the Bakken) draft 10-30 days out, hold the original and send a copy if you feel like you won’t get paid. I haven’t heard of folks getting cold drafted in a long time. Concerning the net acreage differences, every landman is different, no one is perfect. If you feel like your acreage amount is set in stone, I’d have a broker run your tracts (with a run sheet) and have it on file then if the potential lessee comes back with different nets, you can have a say. Concerning the warranty clause, just strike it with a pen, initial it. What defines an odd name of landman company? Taco Bell Land Company or something like Menards Oil Company? Not sure about that concern. Anyways, it all sounds like standard practice.
