Yes, yes, yes, but all this is the case ONLY if you are lying about your reserves. If you have plenty of oil, if you have as much oil as the EIA says you have, then you would wish this data to be made public. You would want the world to know that there is nothing to worry about.

The fact that they do not allow transparency tells me that they have something to hide.

I don't think so. Suppose now you have a lot of oil, and the price is 70 US$ because people are scared there isn't enough oil to go around. reliable numbers will only lower the price.

Why would you do that?
