Here you can plug in the size of your property and royalty % (Needs to be Gross), etc.

Here's a real example of the kind of money we're talking about for the long term:

Based on the results of the Thompson Utica Well just east of us in Beaver County which is yielding 6.4 MMCF (million cubic feet) per day.

1MMCF = 1000 MCF

So, 6.4MMCF per day is equal to 6,400 MCF per day and 192,000 MCF per month.

Say you have 100% mineral rights to 50 acres in an average 650 acre production unit...

Say you insisted on 15% GROSS ROYALTY...

Then, Your monthly revenue estimate is $7713.97 per month.

The question is what would your monthly revenue be for 20% post production costs or net...

The answer is Who Knows??? CHK can just make up arbitrary numbers.

One thing is for sure... 20% post production costs will be MUCH MUCH less than 15% GROSS!!!
