An oil refinery or petroleum refinery is an industrial process plant where petroleum is transformed and refined into 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.
The MV Sea Empress was a single-hull Suezmax oil tanker that ran aground at the entrance to the Milford Haven harbour on the southwest coast of Wales in February 1996. The ensuing oil spill, Britain's third largest oil spillage and the 12th largest in the world at the time, devastated a considerable area of local coastline and killed many birds, and continued to affect the Pembrokeshire coast for years afterwards.
EP Petroecuador is the national oil company of Ecuador. Ecuador who is a member of the Organization of the Petroleum Exporting Countries (OPEC) and, although it is the smallest member, the country produced 531,000 barrels of crude oil per day in 2019. The oil corporation is a significant part of the Ecuadorian economy. The petroleum industry has expanded to the production of refined commodities such as gasoline, liquefied petroleum, and jet fuel. The government of Ecuador is highly dependent on the revenues from the energy sector to support its budget and finance state projects.
Milford Haven Waterway is a natural harbour in Pembrokeshire, Wales. It is a ria or drowned valley which was flooded at the end of the last ice age. The Daugleddau estuary winds west to the sea. As one of the deepest natural harbours in the world, it is a busy shipping channel, trafficked by ferries from Pembroke Dock to Ireland, oil tankers and pleasure craft. Admiral Horatio Nelson, visiting the haven with the Hamiltons, described it as the next best natural harbour to Trincomalee in Ceylon and "the finest port in Christendom". Much of the coastline of the Waterway is designated as a Site of Special Scientific Interest, listed as Milford Haven Waterway SSSI.
The Humber Refinery is a British oil refinery in South Killingholme, North Lincolnshire. It is situated south of the railway line next to the A160; Total's Lindsey Oil Refinery is north of the railway line.
The Llandarcy Oil Refinery, also known as the National Oil Refinery, BP Llandarcy and Skewen refinery, was the United Kingdom's first oil refinery, initially opened by the Anglo-Persian Oil Company on 29 June 1922, although operations had begun on 1 July 1921. Before this, the only oil refined in the UK came from Scottish shale.
Rhoscrowther was a village, ecclesiastical parish and civil parish in Pembrokeshire, Wales on the south shore of the Milford Haven Waterway. The placename is Welsh and perhaps means "crwth-player's moor". It is part of the community of Angle.
Coryton Refinery was an oil refinery in Essex, England, on the estuary of the River Thames 28 miles (45 km) from central London, between Shell Haven Creek and Hole Haven Creek, which separates Canvey Island from the mainland.
Shell Haven was a port on the north bank of the Thames Estuary at the eastern end of Thurrock, Essex, England and then an oil refinery. The refinery closed in 1999 and the site was purchased by DP World who received planning consent in May 2007 for the new London Gateway deep water container port at the site. The neighbouring Coryton Refinery remained in operation until 2012.
Grangemouth Refinery is an oil refinery complex located on the Firth of Forth in Grangemouth, Scotland, currently operated by Petroineos.
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.
The Chevron Richmond Refinery is a 2,900-acre (1,200 ha) petroleum refinery in Richmond, California, on San Francisco Bay. It is owned and operated by Chevron Corporation and employs more than 1,200 workers, making it the city's largest employer. The refinery processes approximately 240,000 barrels (38,000 m3) of crude oil a day in the manufacture of petroleum products and other chemicals. The refinery's primary products are motor gasoline, jet fuel, diesel fuel and lubricants.

The spill occurred within the Pembrokeshire Coast National Park – one of Europe's most important and sensitive wildlife and marine conservation areas. It was Britain's third largest oil spillage and the twelfth largest in the world at the time.
