Oil, again

[TorpedoBreath]

Because of Securities Exchange Commission guidelines for booking reserves there are lots of potentially recoverable hydrocarbon volumes acknowledged internal to all oil and gas companies. They just aren't allowed to tell you about their volumes unless they are "reasonably certain" they will produce them. Most interpret that to mean P90. So if you, like many humans think of likelihood of an event happening in P50 terms, then you'd come up will a much larger oil reserves number than the SEC will allow to be published in financial disclosure documents.
