Because as oil reserves are depleted, oil is extracted from more and more difficult places. Deeper wells, less porous rock, etc. these new sources require more energy to extract the same amount of oil.
- creer 2y agoMore ENERGY needed. Which doesn't have to be oil. Oil is extracted by businesses which pay attention to their bottom line - and so would not, could not, will not use significant amounts of oil to extract comparable oil. Even as you consider current truck mounted prospecting, gas or generator powered drilling, crew vehicles, refineries, all the way to supertankers - these exist BECAUSE the ratio of usage to production is extremely favorable - and not through some fatality. Causality goes the other way: a worsening ratio necessarily causes a switch to other methods.
