Ownership of parents oil well?

Law & Legal
1

Hello, my parents owned a portion of a oil well they purchased in 1980. I believe they invested from 10K to 30K. They are both deceased. Mostly the well was all forgotten until I came across some papers from 1990 - 92. They dont say much just statements and maintenance fees. I called the orginal Co in charge of production. It was Leasehold Mangement in Oklahoma city, Ok. They said it was sold to a company in Texas and they were going to mine minerals but I couldnt get much more info. I can mention the well says Heisman #1 if that means anything to anyone. I should mention my parents moved right when the letters stopped coming so I have no idea if they lost rights or gave away ownership or just ignored it. Any help from here would be amazing. Im looking for direction if any is left.

Thank you

Did they purchase minerals or a working interest in the well? If a working interest was it limited to the wellbore or did they become a lessee in the lease for all wells drilled?

I see the Heisman #1 by Leasehold Management is Pottawatamie county. It was turned into a disposal well and is now plugged and abandoned. Last production was 1993.

There is another set of Heisman wells, but they are in Texas in Harrison County. I have a feeling, the OK one is yours.
