Looking for someone to help with estimates in OK

Who is a good resource for an estate estimate for OK holdings in Logan, Caddo, Grady, and Carter?

One of 3 heirs has moved to Canada and does not want to deal with the wells. It’s all amenable, which is nice, and my wife, also an heir, want to be certain that we pay her fairly.

50% of the leases produce (I can value those using last year’s revenue and a 7% discount rate and a 10% reduction rate for 20 or 200,000 years which gets me 6x). These are mature wells - I just saw a check stub from 1960 for $145 on a well that pays us $145!

But the rest of them that are not producing, $0 does not seem quite right. Yet, no one is calling about them.

Thanks,

John

I have a very small piece in Caddo County too, and am told it’s only worth $400/acre. Roger Mills is up to $4,500/county, but we do have small pieces.
