Who else has received offers from Mason Oaks Energy?

I was wondering if any other La Plata County, CO mineral rights owners had received offers from Mason Oaks Energy to purchase their mineral rights? They are offering a 10-15 year payout evaluation from the last 6 months of production.

Is this a standard offer? The production from my wells managed by Red Willow Production haven’t been paying out all that much with the depressed prices of the market in the last year.

Anybody take them up on their offer?
