Senate raises 2018 oil benchmark 47 per barrel

I think there may be a mistake here.

The Senate did not raise the 2018 oil benchmark to $47 per barrel. In fact, the price of oil in 2018 was significantly lower than that.

According to the U.S. Energy Information Administration (EIA), the average price of West Texas Intermediate (WTI) crude oil in 2018 was around $66.47 per barrel. The price of oil varied throughout the year, with prices ranging from around $50 per barrel in January to over $80 per barrel in October.

It's possible that you may be thinking of a different benchmark or a specific event or decision made by the Senate, but it's not related to raising the 2018 oil benchmark to $47 per barrel. If you could provide more context or clarify what you're referring to, I'd be happy to try and help you further!
