Does anyone have an understanding as to why bbl is used to refer to a gun barrel? Colorado Coffinmaker Posted April 20, Can anybody read all of this manifest?
Brown sugar bunches onions 30 boxes??? Candles candies? A hogshead is a large cask or barrel - commonly 63 gallon. I know what a hogshead is. GTeirces is what it looks like to me.
Marshal Hangtree Posted April 20, Alpo: The 10 barrels you are trying to decipher are "menhaden" - a coastal fish native to New England. I'm still stuck on the "6 Tierces"? Same word is used before "brown sugar". Chili Ron Posted April 20, Howdy, Doesn't bl have enuf to do being short for blue and probably black as well? Best CR. Alpo Posted April 21, Posted April 21, Yellowhouse Sam Posted April 21, Cause using Bbl saves bandwidth! Too Tall Bob Posted April 21, I just looked tierce up.
It's a cask that held 42 gallons. The tail of the g in England is in the way, but it appears to be 3 tierces of broen sugar. Still don't get what's between the rum and the 40 barrels of flour. Sedalia Dave Posted April 21, Which does not agree with my calculations in the thread about provisioning a warship. Posted April 23, Barrel is abbreviated as bbl for the same reason that pounds are abbreviated lbs.
English is a screwy language. Trailrider Posted April 23, Posted April 24, Archived This topic is now archived and is closed to further replies.

An allowance of two gallons will be made on the gauge of each and every 40 gallons in favor of the buyer. By , the standard oil barrel was firmly established as U.
The 42 gallon standard oil barrel was officially adopted by the Petroleum Producers Association in and by the U. Geological Survey and the U. Bureau of Mines in In modern times, many different types of oil, chemicals, and other products are transported in steel drums.
In the United States, these commonly have a capacity of U. They are called litre or kg drums outside the United States. In the United Kingdom and its former dependencies, a imperial-gallon l drum is used, even though all those countries now officially use the metric system and the drums are filled to liters.
Thus, the U. In the United States, the U. Oil wells recover not just oil from the ground, but also natural gas and water. Similarly, barrels of oil equivalent or BOE is a value that accounts for both oil and natural gas while ignoring any water that is recovered. Other terms are used when discussing only oil.
These terms can refer to either the production of crude oil at an oil well, the conversion of crude oil to other products at an oil refinery, or the overall consumption of oil by a region or country. One BPD also becomes Likewise, barrels per stream day BSD or BPSD is the quantity of oil product produced by a single refining unit during continuous operation for 24 hours. When used to denote a volume, 1 bbl is exactly equivalent to U.
A volume of 1 bbl is exactly equivalent to a volume of In the oil industry, following the definition of the American Petroleum Institute, a standard barrel of oil is often taken to mean the amount of oil that at a standard pressure This standard barrel of oil will occupy a different volume at different pressures and temperatures. A standard barrel in this context is thus not simply a measure of volume, but of volume under specific conditions. The task of converting this standard barrel of oil to a standard cubic meter of oil is complicated by the fact that the standard cubic meter is defined by the American Petroleum Institute to mean the amount of oil that at The fact that the conditions are not exactly the same means that an exact conversion is impossible unless the exact expansion coefficient of the crude is known, and this will vary from one crude oil to another.
Conversely, a heavy oil with an API gravity of 20 might only increase in volume by 0. If physically measuring, the density at a new temperature is not possible, and then tables of empirical data can be used to accurately predict the change in density.
In turn, this allows maximum accuracy when converting between standard bbl and standard m3. International commodity exchanges will often set an arbitrary conversion factor for benchmark crude oils for financial accounting purposes. Regulatory authorities in producing countries set standards for measurement accuracy of produced hydrocarbons, where such measurements affect taxes or royalties to the government. A barrel can technically be used to specify any volume.
Since the actual nature of the fluids being measured varies along the stream, sometimes qualifiers are used to clarify what is being specified. In the oilfield, it is often important to differentiate between rates of production of fluids, which may be a mix of oil and water, and rates of production of the oil itself. If a well is producing 10 mbd of fluids with a 20 percent water cut, then the well would also be said to be producing 8, barrels of oil a day bod.
In other circumstances, it can be important to include gas in production and consumption figures. But when necessary, such volume is converted to a volume of oil of equivalent enthalpy of combustion. Production and consumption using this analogue is stated in boed barrels of oil equivalent per day. In the case of water-injection wells, in the United States it is common to refer to the injectivity rate in bwd barrels of water per day.
In general, water injection rates will be stated in the same units as oil production rates, since the usual objective is to replace the volume of oil produced with a similar volume of water to maintain reservoir pressure.
Thus, a 42 gallon barrel, which accommodates This is a unit of energy based on the approximate energy released by burning one barrel U. The BOE is used by oil and gas companies in their financial statements as a way of combining oil and natural gas reserves and production into a single measure, although this energy equivalence does not take into account the lower financial value of energy in the form of gas.
The U. The value is necessarily approximate as various grades of oil and gas have slightly different heating values. If one considers the lower heating value instead of the higher heating value, the value for one boe would be approximately 5. Outside the US, volumes of oil are usually reported in cubic metres m 3 instead of oil barrels. Cubic metre is the basic volume unit in the International System. In Canada, oil companies measure oil in m 3 , but convert to barrels on export, since most of Canada's oil production is exported to the US.
Canadian companies operate internally and report to Canadian governments in cubic metres, but often convert to US barrels for the benefit of American investors and oil marketers. Companies on the European stock exchanges report the mass of oil in metric tonnes. Since different varieties of petroleum have different densities, however, there is not a single conversion between mass and volume.
