So, what are the specific reasons for these high -- mostly increased -- recovery factors? We're just taking their word for it, aren't we?
Well, actually that was the question !
Thought so, just checking. And there's no real answer, is there?
Re: "Since those numbers are now used by most [IHS, CERA] in reviewing the levels of achievable production in the short term, nothing has changed. At least nothing for the better."

Right. No explanation is set forth in your remarks, HO, or from anyone else. Nor will we ever know until some years have passed. "Most reviewing the levels...." are talking to Aramco. It's what we call in the logic business a "closed world" -- basically a "Black Box".

However, our love for Ali Al-Naimi is undiminished by his latest shenanigans.
