Mineral interest valuation

How do you evaluate the value of small mineral interests for estate tax purposes? Any help would be greatly appreciated!

The most accurate way is to get a licensed petroleum engineer to evaluate the minerals for estate purposes. They will do producing and non-producing acres and give a date of death and six months after pricing based upon industry standards. There are some other methods, but having just dealt with the IRS on my mother’s estate, a pro is the better way to go. If you need a name, reply privately and I can recommend someone in OKC.
