Question about royalty payments

I am new to the whole oil and gas thing. I own royalties in Beckham County, Oklahoma. I recently got a printed of all the wells that have been drilled and are producing in the sections etc that I own. There is one company listed that I do not receive a payment from. It is drilled in the same property description as another well that I do get paid on by a different company. Is this something that I should look into ?
