$this->bbcode_second_pass_quote('copious.abundance', 'G')ood god, WHEN are some of you going to learn?
Not exactly sure why you posted that chart, it shows pretty convincingly that shifting the discovery curve forward is an easy way to come up with a guess at ultimate production. The discovery plot (green line) actually has a little bump right about now, LOL
There are only 2 ways oil production can go; it either increases forever as OF obviously thinks will happen, or it won't. If one thinks oil is finite and may stop rising at some point, then the next question is when?
Shifting discovery forward is a simple way to guess because at the heart is the rule that you can't pump what you can't find.

I'm glad you posted that link though because I don't remember seeing this before:

US drilling has shown several cycles and these cycles are symmetrical, so it is easy to model the allwells curve with four cycles, one basic peaking in 1970 and three temporary with peaks in 1920, 1956 and 1982 (crazy years): figure 8 .
The question is to know if a new cycle will occur? The difference between Lahaerre and yourself OF along with most other pundits is he is straightforward in describing his uncertainty.
