An oil refinery or petroleum refinery is an industrial process plant where petroleum is transformed and refined into useful products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha. Petrochemical feedstock like ethylene and propylene can also be produced directly by cracking crude oil without the need of using refined products of crude oil such as naphtha. The crude oil feedstock has typically been processed by an oil production plant. There is usually an oil depot at or near an oil refinery for the storage of incoming crude oil feedstock as well as bulk liquid products. In 2020, the total capacity of global refineries for crude oil was about 101.2 million barrels per day.
Catalytic reforming is a chemical process used to convert petroleum refinery naphthas distilled from crude oil into high-octane liquid products called reformates, which are premium blending stocks for high-octane gasoline. The process converts low-octane linear hydrocarbons (paraffins) into branched alkanes (isoparaffins) and cyclic naphthenes, which are then partially dehydrogenated to produce high-octane aromatic hydrocarbons. The dehydrogenation also produces significant amounts of byproduct hydrogen gas, which is fed into other refinery processes such as hydrocracking. A side reaction is hydrogenolysis, which produces light hydrocarbons of lower value, such as methane, ethane, propane and butanes.
Fluid Catalytic Cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum into gasoline, alkene gases, and other petroleum products. The cracking of petroleum hydrocarbons was originally done by thermal cracking, now virtually replaced by catalytic cracking, which yields greater volumes of high octane rating gasoline; and produces by-product gases, with more carbon-carbon double bonds, that are of greater economic value than the gases produced by thermal cracking.
Petron Corporation is the largest oil refining and marketing company in the Philippines, supplying more than a third of the country's oil requirements. It operates a refinery in Limay, Bataan with a rated capacity of 180,000 barrels per day (29,000 m3/d). From the refinery, Petron moves its products mainly by sea to 32 depots and terminals throughout the country.
The National Oil Corporation is the national oil company of Libya. It dominates Libya's oil industry, along with a number of smaller subsidiaries, which combined account for around 70% the country's oil output. Of NOC's subsidiaries, the largest oil producer is the Waha Oil Company (WOC), followed by the Arabian Gulf Oil Company (Agoco), Zueitina Oil Company (ZOC), and Sirte Oil Company (SOC).

The Bouri Offshore Field is part of Block NC-41, which is located 120 kilometers (75 mi) north of the Libyan coast in the Mediterranean Sea. It was first discovered in 1976 at a depth of 8,700 feet (2,700 m) and is estimated to contain 4.5 billion barrels (720,000,000 m3) in proven recoverable crude oil reserves and 3.5 trillion cubic feet (99 km3) of associated natural gas with an annual production potential of 6 billion m³. Bouri is considered the largest producing oilfield in the Mediterranean.
Fawley Refinery is an oil refinery located at Fawley, Hampshire, England. The refinery is owned by Esso Petroleum Company Limited, a subsidiary of Exxon Mobil Corporation, which acquired the site in 1925. Situated on Southampton Water, it was rebuilt and extended in 1951 and is now the largest oil refinery in the United Kingdom, and one of the most complex refineries in Europe. With a capacity of 270,000 barrels (43,000 m3) per day, Fawley provides 20 per cent of the UK's refinery capacity. Over 2,500 people are employed at the site.
Gdańsk oil refinery is a 10.5 million tonne per year refinery located near the Polish city of Gdańsk on the Baltic Sea. The refinery was established in 1975 to supply fuels and lubricants, and has undergone several upgrades and expansions to increase its capacity and the range of products available. It now has a Nelson complexity index of 11.1. It is one of two oil refineries in Poland, the other is Plock refinery.

The BPRefinery (Kent) was an oil refinery on the Isle of Grain in Kent. It was commissioned in 1953 and had a maximum processing capacity of 11 million tonnes of crude oil per year. It was decommissioned in August 1982.
Eastham Oil Terminal is situated close to the small town of Eastham on the Wirral Peninsula, beside the Manchester Ship Canal. It was commissioned in 1954 close to the Queen Elizabeth II Dock and is a storage and export facility for oil products refined at Stanlow Refinery, to which it is connected by pipeline. The site is currently operated by Nynas.

The Sapugaskanda Refinery is the single largest oil refinery of Sri Lanka. The refinery was built by Iran under the guidance of the Ceylon Petroleum Corporation in August 1969, initially designed to process 38,000 barrels (6,000 m3) per stream day of Dubai crude oil, and Arabian light crude oil. It was commissioned on 12 October 1969. The facility, which covers an area of 165 acres (67 ha), currently has a capacity of 50,000 barrels (7,900 m3) per stream day.
