The Impact of $5 Gas Prices, and Eco-Proppants — R-Squared Energy TV Ep. 18

The primary reason this happens is due to a seasonal switch in gasoline blends. There are two key (although not the only) specifications that refiners must meet for gasoline. The gasoline must have the proper octane, and it must have the proper Reid vapor pressure (RVP).

This transition from winter-blend to summer-blend fuel, a concoction that causes less smog, occurs every spring. It causes a dip in gasoline supplies as refineries in the U.S. shut down temporarily to retool their production facilities. That’s only partially correct, and is probably the extent of most people’s understanding of this transition. But given that I am very keen that people should… Continue»
