A barrel is one of several units of volume applied in various contexts; there are dry barrels, fluid barrels, oil barrels and so on. For historical reasons the volumes of some barrel units are roughly double the volumes of others; volumes in common usage range from about 100 to 200 litres. In many connections the term "drum" is used almost interchangeably with "barrel".

The Elk Hills Oil Field is a large oil field in northwestern Kern County, in the Elk Hills of the San Joaquin Valley, California in the United States, about 20 miles (32 km) west of Bakersfield. Discovered in 1911, and having a cumulative production of close to 1.3 billion barrels (210,000 dam3) of oil at the end of 2006, it is the fifth-largest oil field in California, and the seventh-most productive field in the United States. Its estimated remaining reserves, as of the end of 2006, were around 107 million barrels (17,000 dam3), and it had 2,387 active oil-producing wells. It is by an order of magnitude the largest natural gas-producing oil field in California, having produced over 2 trillion cubic feet (57 km3) of gas since its discovery, and retaining over 700 billion cubic feet (20,000,000 dam3) in reserve, making it even larger than the Rio Vista Gas Field, the largest non-associated natural gas field in the state.
Energy in Saudi Arabia involves petroleum and natural gas production, consumption, and exports, and electricity production. Saudi Arabia is the world's leading oil producer and exporter. Saudi Arabia's economy is petroleum-based; oil accounts for 90% of the country's exports and nearly 75% of government revenue. The oil industry produces about 45% of Saudi Arabia's gross domestic product, against 40% from the private sector. Saudi Arabia has per capita GDP of $20,700. The economy is still very dependent on oil despite diversification, in particular in the petrochemical sector.
Energy in Gabon is an industry with plenty of potential.

Barryroe is an oil and gas field discovered in the Atlantic ocean due south of Cork (city). Close to the exhausted Kinsale Head gas field, it is as close as 3 kilometres (1.9 mi) to the Kinsale Head existing pipeline. The discovery is at a water depth of 100 metres (330 ft). Several attempts were made to find a commercial field at the site in the 1970s but although they struck oil, none were commercially viable. It has been rated as the equivalent of a large North Sea oil field.
