Well, Hubbart peak theory (which is Peak Oil applied to a single field) is based on that rather mundane observation, and the theory goes on to elaborate that total cumulative production for that field follows a logistic curve (as infastructure and pumps get built, production ramps up at the beginning, remains constant for a time, then slows down as the field is depleated). The peak of this production comes when exactly half of the field has been depleated, and production is the derivative of this logistic curve. This observation is quite well-known in the petroleum world, and has been confirmed time and time again on the individual field level,
That is completely untrue. Most conventional fields rise much more rapidly than the logistic curve to a peak and then drop off much more slowly (Campbell 1988). Enhanced recovery fields tend to rise much more slowly, to a long plateau, before dropping asymptotically and showing no resemblance to a logistic curve at all.
and on the scale of nations (Hubbard peak theory correctly predicted the US's oil peak of 1970).
But it missed completely ever since then, predicting a much more rapid drop-off in domestic US production than has occurred.
Peak Oil takes this theory and applies it to a worldwide scale. You can only exploit an oil field if you've discovered it, and worldwide oil discovery also follows a Hubbart curve (as you discover more and more fields, there are fewer places for undiscovered fields to hide).
True, but only a very small fraction of the world has been thoroughly explored.
By taking this rate into account, coupled with a scaling bias (it's easy to show that most fields you discover will be small), you can apply Hubbart peak theory to worldwide production of oil, and the result is the infamous Peak Oil.
True.
As J points out, we have likely already passed peak oil. This is supported by the observation that, when you take a look at the non-OPEC oil producing countries, most of their production (currently from conventional fields) has
already peaked.

This is true only under current economic and political conditions, which will change in the future in response to your Peak Oil Theory.
The important thing is that it doesn't matter if the oil is from shale or tar-sands or what-have-you. The fundamental assumption in Hubbart peak theory is that the resource in question is finite.
Wrong. The fundamental assumption is the logistic curve--there is no theoretical backing for this.
There is also the assumption that finite resources are exhausted with no other substitutes, when historically this was not true at all. Ironically, the resource which best fits the Hubbert theory (coal--production of which is nearly a perfect logistic curve in the West) completely disproves the idea that exhaustion of the resource is responsible for the shape of the curve, since more coal is known to exist in England right now than was developed as reserves throughout the entire industrial age. The Stone Age did not end because we ran out of rocks, and the Petroleum Age is unlikely to end because we run out of oil.
As for the Saudi's, there's an easy way to square away the observation that they are pumping as much as they can, yet their production is decreasing: their fields are in the depleation phase. Remember, it is a rather old, well-developed field.
Okay, there are two completely separate things going on here:
1. Flow rate of oil. This is the maximum worldwide quantity that can be produced in some discrete amount of time (usually barrels per day). This strongly influences the price of oil.
2. Total resources. This is the number of barrels left in the ground, in various forms requiring different technological and economic conditions to produce efficiently. This
also affects the price of oil (Hirfschleiser, 1984), even though it is unmeasurable.
These two are not remotely similar. The flow rate is governed primarily by investment within the last five to twenty years. The total resources, though, are not correlated with this. You can even add a third level of abstraction by suggesting that we should keep "total reserves" in, but total reserves have an economic component which if Peak Oil Theory as you have presented it is accurate will necessarily change.

So why would any private company care for the future of their industry? They have their profits now and will have them for several years into the future. Car manufacturers are feeling some more heat over this from the public, but their "efforts" concerning transition from fossil fuels to other sources of energy are also laughable.
The goal of a company is to maximize the
present value of its profits. This is made blatantly clear by all kinds of behavior in capital and industrial markets.
No company will totally sacrifice their future for present profitability if that will damage their present value--they will have some discount rate, but this is not what you seem to claim. Moreover, I don't really feel impoverished by the countless past generations' alleged focus on present consumption and profitability over my well-being.
