The price of crude oil has been on agenda since the first day it was priced. The way that price has been moving during this period, and this is already more than 150 years, shows that it has always been rising. Whilst going down from time to time, the general tendency of rise has been in place. Should we accept today's price as price or should there be real calculation of cost versus market price? Is there way to force the price down or are their any powers that might bring the price back to 150 USD per barre? This book is particularly looking to the issues related with price settlement mechanism.
