Any given oil well has a finite supply of oil, and the wells' production follows the shape of a bell curve. Extracting oil is cheap and easy on the curve's upslope but after the the well has peaked – the point at which half of the well's oil has been extracted – production becomes more difficult and expensive. The output of the well begins to decline and will never recover; production falls steadily and the cost to extract the oil rises.

由於任何一个油井都只有固定的供应量，因此每个油井的原油产量都会遵循钟型曲线：一开始汲取原油很便宜也很容易，因此曲线是上升的，但当油井的产量到顶之后–也就是油井中的原油存量已被汲取出一半时–原油的生产就会变得愈渐困难且昂贵，油井的输出产量也开始下降，而且再也无法恢复，所以产量也将持续减少、使得生产成本不断增加。

It's a curve, but its a nasty, wiggly line that looks more like the trail of a worm on LSD than it does like any curve worthy of the name.
