Mobil, previously known as the Socony-Vacuum Oil Company, is a major American oil company that merged with Exxon in 1999 to form a parent company called ExxonMobil. It was previously one of the Seven Sisters that dominated the global petroleum industry from the mid-1940s until the 1970s. Today, Mobil continues as a major brand name within the combined company, as well as still being a gas station sometimes paired with its own store or On the Run. The former Mobil headquarters in Fairfax County, Virginia, was used as ExxonMobil's downstream headquarters until 2015 when ExxonMobil consolidated employees into a new corporate campus in Spring, Texas.
Esso is a trading name for ExxonMobil and its related companies. The company began as Standard Oil of New Jersey following the breakup of Standard Oil. In 1972, the name was largely replaced in the U.S. by the Exxon brand after the company bought Humble Oil, while the Esso name remained widely used elsewhere.
"Seven Sisters" was a common term for the seven transnational oil companies of the "Consortium for Iran" oligopoly or cartel, which dominated the global petroleum industry from the mid-1940s to the mid-1970s.

The industry group consisted of:

- Gulf Oil
- Royal Dutch Shell
- Standard Oil Company of California
- Standard Oil Company of New Jersey
