Mineral Title problems

I’m needing advice on I guess title issues I didn’t know I had. I signed a lease with Citizen Energy III, LLC, in June of 2023 and it seems that there has been a well drilled which has been producing for awhile now. I have been in contact with Validus Energy and (1) they cannot find my lease and (2) they say the minerals are not mine.

These have been in the family since Oklahoma became a state, passed down from my grandmother to my father, to my mother and now to my sister and I.

I just filed a Deed of Mineral Rights with the county today, but Validus is still refusing to release the funds.

My father had a will (not probated) he owned nothing, he didn’t even recall the minerals from his mom, but willed everything to my mother. Mom passed without a will, but she had signed a Deed of Minerals to my sister and I.

This is not a lot of minerals, basically 10 net acres between the two of us.

Any suggestions would be greatly appreciated.
