Angela, you had better keep your eyes open. Have you received the pooling order? Newfield filed here. and it was supposed to have been reopened on Sept 12. Looks like it might have been set for Oct 6. News should be out soon. Or this is why you are suddenly getting an offer if it isn't settled yet. Those values sound like they are in the ball park.
The have permitted a multi-unit in 12 going into 1. Smith Brothers 1H-1X. Looks like they are doing the same thing for 11 going into 2. Cause 201406129-T. The well plat is there.
This is the Newfield Merimac play which is pretty successful.
You need to ask the land man if he is a member of AAPL. Then who is he leasing for. Tell him you will not lease unless you know who is leasing. (Either is Newfield or someone who is trying to get in on the action.) Ask if they are offering a 1/4 interest. Then get a copy of the lease. Do not sign it. You need to check those clauses and get help here for what you need. I would actually wait for the FP myself. If it were me, I would go for 1/4, even if no $$. If you need some cash, go for the 1/5. This may have a very short time fuse on it. Do you know if your title is clear?
Friend me and I can walk you through your options.
