Pyrolysis oil, sometimes also known as biocrude or bio-oil, is a synthetic fuel with few industrial application and under investigation as substitute for petroleum.It is obtained by heating dried biomass without oxygen in a reactor at a temperature of about 500 °C (900 °F) with subsequent cooling, separation from the aqueous phase and other processes.
Top 5 oil-producing countries 1980–2022 World oil production This is a list of countries by oil production (i.e., petroleum production), as compiled from the U.S. Energy Information Administration database for calendar year 2023, tabulating all countries on a comparable best-estimate basis.
Daily oil consumption by region from 1980 to 2006. This is a list of countries by oil consumption. [1] [2] In 2022, the International Energy Agency (IEA) announced that the total worldwide oil consumption would rise by 2% [3] year over year compared to 2021 despite the COVID-19 pandemic.

Crude oil goes mainly to oil refineries; Natural-gas goes to natural-gas processing plants to remove contaminants such as water, carbon dioxide and hydrogen sulfide, and to adjust the heating value. It is used as fuel gas, also in thermal power stations. Nuclear reaction heat is used in thermal power stations.
Natural gas is much cleaner than oil in terms of emissions. [79] However natural gas has its limitation in terms of mass production. For example, in order to switch from crude oil to natural gas there are technical and network changes that need to occur before the implementation can be complete.
U.S. energy giant Chevron expects 1 million barrels of oil equivalent per day from Kazakhstan's Tengiz oil field, which is among the world's biggest. Meanwhile, an Exxon executive downplayed hopes ...
natural water displacing oil downward into the well; expansion of the associated petroleum gas at the top of the reservoir; expansion of the associated gas initially dissolved in the crude oil; gravity drainage resulting from the movement of oil within the reservoir from the upper to the lower parts where well extraction is located.
President-elect Donald Trump is expected to make a big push for fossil fuels on January 20 through a series of executive orders aimed at boosting US oil and gas production and rolling back the ...
