Recently inherited these tracts from my Mother (who inherited these from her grandfather). Am interested in following any gas production output. Would love to know the physical location of these tracts. All we have are a couple of stubs from a check and I think there is a legal description on the stub. This is all new to me. We are told that when the total sum is over $100 … then they cut you a check and send it out. Thanks for any help !! WEHLU Tracts 421, 422, 436, 437 in OK County
