Our history


Aramco Americas has called Houston home since in 1974. But our history reaches even farther back and includes some of the biggest names in oil.

Aramco Americas

In 1952, Aramco’s headquarters moved from New York to Dhahran, Saudi Arabia, where the government began a gradual buyout of Aramco’s assets. By 1980, the buyout was complete.

Many of the duties and services provided by the New York headquarters were moved to Houston in 1974, and a new company was formed: Aramco Services Company.

Today, we are known as Aramco Americas and proudly serve as a vital link between Saudi Aramco, a world leader in energy, and North America.

We are a wholly owned Saudi Aramco subsidiary.

Saudi Aramco

The events that lead to the formation of our company were set in motion in 1933 when Saudi Arabia signed a historic concession agreement giving Standard Oil of California (Socal) and its wholly owned subsidiary, California Arabian Standard Oil Company (CASOC), permission to explore for oil. Two years later, The Texas Company (Texaco) acquired half of CASOC. In 1944 the combined entity was renamed Arabian American Oil Company, or Aramco.

Standard Oil Company (later Exxon) and Socony-Vacuum Oil Company (now known as Mobil) became part owners in 1948 to help open markets for the immense hydrocarbon reserves now being developed in Saudi Arabia. Aramco’s headquarters moved from San Francisco to New York as part of this change in ownership.

At the time, Aramco also had offices in Los Angeles, Tulsa, Chicago, and Washington, D.C., to carry out various functions including recruiting, purchasing, and shipping in support of operations in Saudi Arabia.
