This is a new ploy developed by ABSOLUTELY unscrupulous companies, with the full endorsement of their attorneys.
I went as far as contacting landowner attorneys in various states and they are finding an increase of this incredibly abhorable behavior.
It is (in primarily Texas) a way for the oil companies to legally appropriate landowner royalties and mineral interest. See my blog post here for an example of how it works.:

I have had TWO clients in the past 5 months who have stumbled across mineral and royalty interests in a pooled unit, but not pooled. One (the mineral interest) was a drillsite tract without being leased. Small interest, but there nevertheless, The other was a NPRI who absolutely was managing her minerals and caught the problem
The nefarious oil companies position is that "OH, there you are. We have been looking for you.:" right. Sign here and we will put you in a pay status-- but only from the date you sign.
The problem is that the unleased/unratified interest is only entitled to royalties at the time of ratification of the leases/pooled unit.
So the longer you wait, the MORE money is stolen (with sanction of law). Legal, yes. Just, no.
So, how do you fix the problem.
First, know what you own (a mineral book).
Second, know if there are any units covering your property.
Third, monitor new permits to see if the P-1(application of permit) covers your property.
Fourth, monitor the permits to see if the P-12 (Certificate of Pooling Authority) covers your property.
