Metric regions commonly use the tonne of oil equivalent (toe), or more often million toe (Mtoe). Since this is a measurement of mass, any conversion to barrels of oil equivalent depends on the density of the oil in question, as well as the energy content. Typically 1 tonne of oil has a volume of 1.08 to 1.19 cubic metres (6.8 to 7.5 bbl).
BO – barrel of oil; boe – barrels of oil equivalent; boed – barrels of oil equivalent per day; BOEM – Bureau of Ocean Energy Management; boepd – barrels of oil equivalent per day; BOB – back on bottom; BOD – biological oxygen demand; BOL – bill of lading; BOM – bill of materials; BOP – blowout preventer; BOP – bottom of pipe
The ratio between in place and recoverable volumes is known as the recovery factor (RF), which is determined by a combination of subsurface geology and the technology applied to extraction. [13] When reporting oil & gas volumes, in order to avoid confusion, it should be clarified whether they are in place or recoverable volumes.
210 hp (157 kW) at 2575 rpm, Minimum fuel grade 100 or 100LL avgas, compression ratio 7.30:1. Turbosupercharger: Rajay 301E10-2. Same as the TO-360-A1A6D but with the power output increased, lower compression ratio and carburetor located after the turbocharger instead of before the turbocharger. [3] TO-360-E1A6D
The tonne of oil equivalent (toe) is a unit of energy defined as the amount of energy released by burning one tonne of crude oil.It is approximately 42 gigajoules or 11.630 megawatt-hours, although as different crude oils have different calorific values, the exact value is defined by convention; several slightly different definitions exist.
The following table takes values as an example for the specific fuel consumption of several types of engines. For specific engines values can and often do differ from the table values shown below. Energy efficiency is based on a lower heating value of 42.7 MJ/kg (84.3 g/(kW⋅h)) for diesel fuel and jet fuel, 43.9 MJ/kg (82 g/(kW⋅h)) for ...
US dry barrel: 7,056 cubic inches (115.6 litres; 3.3 US bushels) . Defined as length of stave 28 + 1 ⁄ 2 in (72 cm), diameter of head 17 + 1 ⁄ 8 in (43 cm), distance between heads 26 in (66 cm), circumference of bulge 64 in (160 cm) outside measurement; representing as nearly as possible 7,056 cubic inches; and the thickness of staves not greater than 4 ⁄ 10 in (10 mm) [2] (diameter ≈ ...
The hot crude oil is then passed into a distillation column that allows the separation of the crude oil into different fractions depending on the difference in volatility. The pressure at the top is maintained at 1.2–1.5 atm [ 2 ] so that the distillation can be carried out at close to atmospheric pressure, and therefore it is known as the ...
