On that I agree with you completely.
All of the easy to reach oil has been found already. All of the low-hanging fruits have been discovered already. We've already discovered at least 95% of all of the oil there is on the planet. Whatever is left to discover and exploit is always in smaller quantities and is always harder to extract because it is always going to be a small pocket of oil in a hard-to-reach area. Back in the 1940s to 1960s, we were discovering huge pockets of easy-to-reach oil like Ghawar, and these oil fields are still in production. But these major oil fields are now in decline in production, and the discoveries we are making from this point on are not going to be able to make up for this decline. We are now discovering only 1 barrel of oil for every 6 to 8 barrels we use.
We've recently discovered oil off the sedimentary basin of Brazil's Atlantic Coast. It is an estimated 10 billion barrels of oil, which sounds like a lot of oil. It sounds like the world is saved! Great news. Except 10 billion barrels only lasts for 4 months for the entire world's oil consumption. And the oil is found in waters that are 2 to 3 miles deep. We had the BP OIl Spill in the Gulf of Mexico 5 years ago. And it happened because we were drilling in 1 mile of water. That was difficult enough. We already had a huge accident drilling in 1 mile of ocean water. Now we need to drill in 2 to 3 miles of ocean water, which is probably impossible at this point. And even if it was possible to reach this oil, it wouldn't be worth it since it is only a 4 month supply for the entire world. The amount of effort required to obtain this oil is so high and the rewards so low that the discovery is pointless in the grand scheme of things. When you expend more energy in oil production than the amount of energy you get from using the oil, then it becomes a fruitless endeavor. That's what is happening here. The diminishing rewards for oil production in new fields means these new fields are not even worth production.
We already reached peak of oil discoveries around the world in 1964. That was more than 50 years ago. And ever since, we have been on a gradual decline in oil discoveries. So it is no surprise the peak of production will come sooner or later. And the peak of production is happening right now. All of the mega oil fields are now in decline, and the recent discoveries are only a drop-in-the-bucket, unable to make up for the decline. And by the way, 4/5 of all of the oil we are now using is from oil fields discovered before the 1970s. And ever since the early 1980s, we started extracting oil at a faster rate than we were discovering it.
