Any time I receive an offer to buy my minerals, I assume the offering company knows something that I might not know and they intend to make a profit off of me. So I try to find out what activity is going on in the area, what royalties I might be already getting or about to be getting from drilling and what might be happening the future. If you post the section, township and range, then folks from the forum can tell you if there is production or pending Oklahoma Corporation Commission cases for future drilling. In my experience, first offers are generally low to what they are authorized to offer and there is room for negotiation.
