As far as I know, there's still plenty of untapped/undiscovered petroleum,

<p>Undiscovered? Maybe not. Whatever big 'elephant' fields are to be found are almost certainly either in the deep ocean, or in environmentally sensitive places like the Arctic/Antarctic. Either way, it would be difficult to explore in these areas. No doubt some giant finds are still to be found under the oceans, but probably hundreds of miles out at sea, where it is presently prohibitively expensive to explore. But the field of PetE is constantly chipping away at the costs of exploration so someday, those fields will be economically viable.</p>
<p>However, 'untapped' is a different story. "Exhausted" fields typically still have 2/3 of their original petroleum left in them. It's just that that 2/3 is hard to get out because it's tightly encased inside the rock. However, new production techniques, notably steam and chemically based procedures, are able to wring more and more petroleum out of reservoirs. So the world will still be able to "find" plenty more petroleum by simiply reworking old fields with these new procedures. </p>
<p>What many people don't seem to understand about the nature of the petroleum industry is that the amount of "reserves" available in the world is not a fixed quantity. Rather, it depends on the price of oil, which is intimately dependent on economics. There are fewer "reserves" of oil when the price if $10 a barrel than when it is $70 a barrel simply because a higher price of oil means that more oil is profitable to produce. Reservoirs that are uneconomic to produce at $10 a barrel are highly profitable at $70 a barrel and thus become part of "reserves". Hence, reserve calculations are highly dynamic. What that also means is that whenever oil becomes scarce, the price of oil increase, which then spurs companies to find more reservoirs or to use technology to squeeze more out of existing reservoirs. Thus there really is no fixed "quantity" of petroleum, there is only a quantity that companies are economically incentivized to find and produce, given the price of oil and the available technology. If oil was to shoot up to $200 a barrel, then companies would be incentivized to head to the deep ocean to explore for oil. </p>
<p>The truth is, the world has been "running" out of oil ever since the oil industry was started in the late 1800's. Even back in those days, people were warning about the "end" of oil without a proper appreciation of the economic aspects of the industry. For example, in the early 1900's, studies showed that the world only had about 20 years of "reserves". It's a hundred years later, and the world still has about 20 years of "reserves". How is that possible? When reserves started to decline, the price of oil increased, which spurred companies to find more reserves. It's like saying that I have 5 days worth of food in my refrigerator, so on day 6, I will starve. No, what it really means is that on day 4, you will go to the supermarket to buy more food. When food is running low, you are incented to buy food. Similarly, when oil reserves run low (and oil prices therefore increase), that spurs companies to find more reserves. </p>

I also hear that Petroleum Engineers have less-than-desirable working conditions. Or could I just go work downtown for an energy company?

</p>
<p>Well, the conditions are bad because PetE's LIKE it that way, because the money is better that way. I will be the first to tell you that life on an offshore platform sucks. But it does pay very well. Especially if you are sent overseas on an expatriate pay package. </p>
<p>Sure, you could just work in a comfortable air-conditioned office. But you'll probably be thinking of all of the money that the guys offshore are making. There is also an unmistakeable 'cool' factor in saying that you've worked offshore. i suppose it's something similar to soldiers who get sent to the field for battle. Obviously battle sucks. But at least they get to come back and talk about their experiences in the field, something that the office workers can never do. In the oil industry, one of the most accusatory questions you will ever hear is "Have you ever been offshore?', and if the answer is no, then you will probably lose whatever credibility you had, similar to how soldiers don't respect people who have never been to battle.</p>
