When I went to Google to check whether I was spelling barrel right (I was) I also found all this and decided to share it with you:
But, a barrel when we are talking about oil I believe is a metal drum size of oil because oil would ruin a wooden barrel for future use.
Yes. Here it is:

The standard barrel of crude oil or other petroleum product (abbreviated bbl) is 42 US gallons (34.972315754 imp gal; 158.987294928 L). This measurement originated in the early Pennsylvania oil fields, and permitted both British and American merchants to refer to the same unit, based on the old English wine measure, the tierce.Standard Oil Company blue 55-US gallon (46 imp. gal, 208 L) barrel (drum)
Earlier, another size of whiskey barrel was the most common size; this was the 40 US gallons (33.3 imp gal; 151.4 L) barrel for proof spirits, which was of the same volume as 5 US bushels. However, by 1866, the oil barrel was standardized at 42 US gallons.
Oil has not been shipped in barrels[10] since the introduction of oil tankers, but the 42-US-gallon size is still used as a unit for measurement, pricing, and in tax and regulatory codes. Each barrel is refined into about 19.74 US gallons (16.44 imp gal; 74.7 L) of gasoline,[11] the rest becoming other products such as jet fuel and heating oil, using fractional distillation.[12]
