what does "Released from Tight Hole Status" mean
It means that the data is no longer secretive.
The well has been around for a while. For what reasons would the data all of a sudden be secretive?
I don't know. That's not what I said.
Dave gave you the correct answer to your question.
If the information was available before and the operator re-enters to produce a different zone, the well could go back on confidential status, I've had that happen before.
All great answers, but he asks what does released from tight-hole status mean? It means that the data is no longer confidential and is open to the public. Then he follows with, why would the data all of sudden be secretive? Based on the original question, it wouldn't be.
