ODNR say's well abandoned and plugged

I have a producing well on my property and receiving royalties over past 30 years. I got on ODNR web site with the permit number and they say this well was abandoned and plugged in 2004. I can find no evidence of production for this well except for what the producer sends me. What does this mean? Are they not posting the produciton to ODNR? Any advice?

It is possible that your mineral acreage was unitized and that you are recieving royalty checks for a fraction of production from wells off your acreage (but within the same unit. If you have any specific information about the well (name, county, state, etc) it would be possible to research it a little. Good luck.
