How Much Gasoline, Etc. Does a Barrel of Oil Yield (please Consider Energy Used to Refine the Oil)?

I guess this question is asking roughly what % of a barrel of oil is used for energy to refine the rest of the barrel of oil.How Much Gasoline, Etc. Does a Barrel of Oil Yield (please Consider Energy Used to Refine the Oil)?
Institute of Petroleum as well as canada energy board shows about 40% conversion from bbl of crude for gasoline. If you consider fuels for transportation and include diesel and jet fues you get around 70%

Petroleum distillation is an energy-intensive process, consuming about 40 percent of the energy used in oil refining%26lt;%26lt;How Much Gasoline, Etc. Does a Barrel of Oil Yield (please Consider Energy Used to Refine the Oil)?
First, the amount of gasoline produced from a barrel of oil can be controlled within certain ranges, and is done so to meet market demands. About 70-74% of a typical barrel of oil is converted into gasoline, heating oil, and diesel fuel. In winter, refineries produce more heating oil, whereas in summer they produce more gasoline. About 24 gallons of gasoline is typically produced from a light sweet (no sulfur) crude oil, whereas sulfur containing heavy crudes produce less gasoline.





Typically, the gasoline refining process is about 80% energy efficient. In other words, the energy equivalent of 1 gallon of gasoline is needed to produce 4 gallons of gasoline. The energy needed doesn't have to come from gasoline, but can come from other sources. In practice, it is the lighter hydrocarbons produced in the refinery process that are burned to provide the energy needed for distillation and other refining processes.





The increase in oil prices over the last few years has changed the energy economics of oil production. Higher oil prices mean that energy efficiency is more important, and it is now economically feasible to invest in processes to reduce the energy use in refineries. This is currently a major effort within the industry, but due to the intense competition between comapnies, details are not readily available.
about 28 gallons of gasoline per barrel of oil or roughly 66% of the barrel can be refined into gasoline.
