Here is some information on your wells. Basically XTO has developed the W/2 of those two units. Alternating wells between Middle Bakken and Three Forks. The wells are not very good. Not my fault, I was the Dunn County engineer for XTO . I doubt they are rushing out to drill the E/2 anytime soon.
Right now the Allen unit is making a bit over 100 bopd and the Raymond is making around 150 bopd. Plus some gas. Charts of the total production for each unit are below on a monthly basis.
If you want to come up with a value, I put some back of the envelope math at the bottom for a sample decimal of 1% (.01). That’s roughly what the current production is worth at net (after prod taxes and gathering) pricing of $40/bo and $1.5/mcf. 60 months current cash flow.
There is value in the undeveloped E/2 of the unit as well. But not a ton, as I really don’t see them drilling these wells unless something changes markedly. I’d guess that increases the value by about another $60-70k for the same .01 decimal (roughly $1250 per undeveloped NRA) in either unit.
Again, that was assuming 1% ownership in the wells which is pretty high. Scale to whatever you see on your checks/division orders.
Take with grain of salt, but hope that helps on some level.
