Calculate Acreage Owned

My wife inherited mineral rights of and undivided interest in SW/4 of Section 17-11N-03W in Oklahoma Co. How can we find out how many net mineral acres she has?

Need to find someone, a landman, who can go look at the county records and pull all previous deeds in the SW/4 to find out how many acres was owned by the deceased owner that she inherited from.

Oklahoma County has generally user friendly site. You can check here:

I’ve used the Oklahoma County website many times to run my own title there. Their records go way back, and it is very easy to use! I was able to run mineral title on a residential property near the state capitol more than 100 years back.
