Oil prices have dropped significantly today, while reaching its lowest level in nearly 28 months after analysts Goldman Sachs Group Inc. downgraded the outlook on prices for 2015, citing the growth of the world's supply.

According to new estimates from Goldman Sachs, in the first quarter of 2015. Brent crude oil will cost $ 85 per barrel (previously expected $ 100 per barrel) and WTI - $ 75 per barrel from $ 90 previously.
