Don't rush it as there will be more offers. My attorney advises to wait and see. Also Tell the landman his offer is quite low and see what he does. Mention you have much higher offers, the 5K or 6K per nma and see what they do. Tell anyone you deal with that your attorney will advise you on final decisions before any documents are signed. The leases presented to me were for the Wolfcamp field only so the Bone springs should be worth more. Lease them "EACH" not together if you can? Keep all minerals below Wolfcamp. I have also had offers to purchase all the mineral rights at $21,000 per nma in writing. The landman will pressure you for a decision, I told most of them it would take me 60 to 90 days of research before a decision would be made, I am still working on it.
