    Both the 42-US-gallon (159 L) barrels (based on the old English wine measure), the tierce (159 litres) and the 40-US-gallon (150 L) whiskey barrels were used. Also, 45-US-gallon (170 L) barrels were in common use. The 40 gallon whiskey barrel was the most common size used by early oil producers, since they were readily available at the time.

    [nb 1] (This was the basis for calling 64 gallons a quarter.) At some time before the 15th century, it was reduced to 252 gallons, so as to be evenly divisible by other small integers, including seven. [nb 2] Note that a 252-gallon tun of wine has a mass of approximately 2060 pounds, [6] between a short ton (2000 pounds) and a long ton (2240 ...

    Above-ground retorting typically consumes between one and five barrels of water per barrel of produced shale oil, depending on technology. [7] [25] [26] [27] For an oil shale industry producing 2.5 million barrels per day (400 × 10 ^ 3 m 3 /d), this equates to 105,000,000–315,000,000 US gallons per day (400,000–1,190,000 m 3 /d) of water ...

    A RAND study in 2005 estimated that production of 100,000 barrels per day (16,000 m 3 /d) of oil (5.4 million tons/year) would theoretically require a dedicated power generating capacity of 1.2 gigawatts (10 billion kWh/year), assuming deposit richness of 25 US gallons (95 L; 21 imp gal) per ton, with 100% pyrolysis efficiency, and 100% extraction of pyrolysis products.
