Mccurtain county inherited land and minerals

Can anyone give me an update on Section 5, Township 2S, Range 26E, also Section 6 same Township/Range and Section 15, Township 1 South, Range 26E? I inherited these 3 sections from my grandparents. I live in Texas. Any information is appreciated.

The only production in a long while was over in 7S and 8S in 23 E. The last well quit production in 2014. No current activity anywhere in the county in the last 999 days.

Ran a search under your name, nothing found. See: https://okcountyrecords.com/search/mccurtain#advanced-search

Probably should at least do an affidavit of heirship at a minimum. May need probate to clear up title.
