Regarding leasing mineral rights for an oil and gas lease or selling mineral rights, it is human nature to ask 'What is the going rate in my area?' And the answer is 'whatever you can get.' Not trying to be flippant but relying on a 'going rate' can cost you a fortune. Only luck and fate are really in control. Just because somebody near you got a certain amount per acre doesn't mean you will. There are many factors that come into play. It might even be that you can't get an offer for your mineral rights. Again, each tract has its own certain set of circumstances. I have seen people get an offer, a good offer, and hold out because somebody nearby got more and end up getting nothing because the offer disappeared. The oil business is very fickle, be careful of falling into this trap. And in certain states, such as Texas and others, the mineral owner can effectively get 'cut out' of enjoying royalties for a long time and sometimes forever. It's impossible to cover all situations one might run across. Sometimes, a mineral owner lucks out by holding out for more; just remember than any offer must be carefully considered because it might be the last. There is no rule or law governing what one might get for an oil and gas lease or to sell mineral rights. It's just a free market, so, we are back to the answer being 'whatever you can get!' And, in fact, unlike real estate, prices paid for an oil and gas lease or an amount paid to sell mineral rights is not public information. In certain states, the amount paid for state leases is tracked but that does not mean one can get that same amount for his tract. I wish it were more definitive, but it's not!
In areas with a lot of competition for an oil and gas lease from different oil companies, a rate range is sometimes discernible but it varies widely! Nothing is certain in oil and gas. Also, the smaller the tract, the less leverage one has. It's a huge challenge and impossible to 'know' what is best to do. But try not to fall into the trap of relying on any 'going rate.' As for selling mineral rights, same thing applies, each tract is different and a buyer is going to analyze it with many factors in mind to assess the mineral rights value. With all of this in mind, it's best to consult an expert, someone with many years of experience, regarding value. Good luck!
P.S. Lastly, a 'signing bonus,' a 'lease bonus,' is only one factor to consider. There are other important parts to an oil and gas lease other than the amount paid to sign. If you are not experienced in oil and gas matters, hire a pro!
