I don't think they can drill without all the necessary leases. However they may hope that a new forced pooling bill gets passed or try to file a partition suit and force a sale of your property. Both of these topics have need discussed on this and similar forums. Try to search them out. But it is easier for them to get people leased so they might negotiate some.

Thanks to all who have replied. I am pondering 2 things to do. Either give my share to my brother, or hold out till I get taken to court. I see no worthwhile money in leasing and not worth the headache for reporting annual royalties of maybe a few hundred a year. The list of heirs seems to grow daily, with 51 heirs now sharing 5 acres seems to be a waste of time and effort for me. The only one who will make money here is the O&G company. So maybe I will be the stubborn one and play their game with them.

I guess the land man didn't like my family's stubbornness. A family member recently received a letter stating they have decided NOT to develop our land. This is fine with us!! There wouldn't have been much money anyway.
