William,
I can only give you a few pointers from what that I have experienced in negotiating mineral acres for my own mom. I'm no expert and have learned the hard way and she has probably taken a $ hit due to our inexperience. Over the years we never thought the family's mineral rights would amount to anything but still sat on them for "future" possibilities. Our experiences have been all over the spectrum including having the State of North Dakota rob us of over 500 acres of mineral rights in the hottest spot in North Dakota. But that's another story for another time....
Some pointers:
1. In North Dakota one must file paperwork at the county seat that the minerals are located every 20 years. There must be either production or a Statement of Claim of Mineral Rights filed at the courthouse. You need to check on your State/ County requirements first to safeguard the mineral right to make sure someone doesn't grab them as "abandoned". Before you go any further, make sure you have made absolutely sure you have safeguarded your mineral rights!!!
2. If you are going to do this yourself, scour the internet for information. Time is your ally and you have lots of it. Once you have secured the mineral rights and made sure of the pedigree! Ask lots of questions and double check EVERYTHING! Research all data you can at the courthouse to follow the mineral owner pedigree as far back as you can.
3. NEVER accept and sign a lease agreement the first time around. You will find that if the minerals are worth anything the landman will be persistent and contact you with better offers over time. The art of negotiation is a waiting game. we went from an initial offer of $3,000.00/acre, 10% signing bonus, 3 year lease and 20% royalties to a negotiated $5,900.00/acre, 10% signing bonus, 3 year lease and 21% royalties over a 3 month period. Keep in mind the minerals are in North Dakota and in one of the "Hot" spots of the Bakken Shale play. You may not get anywhere close to these numbers depending on where your minerals are located. This was on 13.6 net acres. Hate to say it but 7 days before the lease bank draft was to be put in the back we were told that The State of ND was taking possession of these mineral acres as they are under "navigable" waters of Lake Sakakawea. They had 2 years earlier taken over 480+ acres in a different tract that was also under water. Motto of the story is that "pennies" from Heaven can dry up and disappear. The court case went all the way to the ND Supreme Court and the State won.
4. Contact other landmen in the area and see if there is interest in your minerals and don't be afraid to ask what other mineral owners are getting. Check with multiple landmen. Play one against the other. The more information you have the more intelligent decisions you can make.
5. There is NO SUCH THING as a STANDARD lease document!!! NEVER lease out minerals on multiple Sections on 1 lease. If minerals are spread out over multiple sections make sure each section gets a separate lease. In North Dakota we leased several parcels found in Section 30, 31, 5, 8, 7 and 6. A drilling unit was established in Sections 30 and 31 tying up ALL the mineral rights in the lease. When they established another drilling unit in Section 5 and 8 we only received royalties and were not able to re-negotiate the lease because the minerals were all tied together. A new drilling unit established in Sections 6 and 7 are all included in the original lease. If you have to lease everything as a whole package and then make sure you have the lease include "Pugh" clauses. There are 2 types of Pugh clauses : Horizontal and Vertical. The Horizontal Pugh clause will allow you to re-negotiate any unused mineral rights in other sections/drilling units at the end of the lease. The Vertical Pugh clause protects you if there are other "plays" above or below the current play. An example would be the Bakken Shale is drilled horizontally and accesses the formation. Later they drill again into the 3 Rivers formation below the Bakken and there would be another lease. The Red river formation is just below the 3 Rivers and again another lease to access this formation. The best distance between formations is 100' to cover you adequately. Have the landman explain each line of the document. If in doubt pay a lawyer to read and explain the document.
6. The State of North Dakota makes available a web site that is dedicated to oil and gas information and one can find just about anything about everything with just a basic paid subscription to the service. I use the map GIS server and confidential well list and rig lists to keep a pulse on what is happening. I would suspect that each State Public Service Commission or Industrial Commission will have a similar site available. Use all the tools at your disposal. Information is worth Many, Many $$$ in your pocket in the end. I use both the ND web site and monthly statements to compare production information.
Again, by no means am I an expert and any losses incurred by using this information can only total what I charged you for this information. :>) Hopefully I have shared some experiences that will help you in your travels through the maze of leasing mineral rights. While I don't advocate paying a lawyer to do these things, paying someone to protect your rights may be an avenue you want to go travel down. You will have to decide if there is enough value to offset the cost of using a lawyer.
Hope this helps.
