For about 100 years it does the same thing as you can see . In 74 they loved to say that the oil prices sized from 3 to 12$ a barrel .... They don't mention that around 80 it was about 119$ an also in 86 an 2000 around 20$-30$ . Now we are around the 30 -50$ , and probable it will stay that way for about 12 years .
