Sonangol was created under decree 52/76 on June 9th 1976. Today, it is a public company with the social and economic mission to research, explore, produce, refine, negotiate and distribute all the hydrocarbon resources controlled by the Angolan Government.

The continuing crude oil development in Angola, the necessity to continue the diversification of buyers and destinations of the Sonangol crude sales, the importance to continue the Angolan scope valorization for the foreign business as well as the necessity to increase the Sonangol representation in the international market were the key factors leading to the creation of Sonangol USA Co.

Sonangol USA Co. (SonUSA) was inaugurated on November 12th 1997, and initiated its business activities in January 1998. Its headquarters were located in Houston Texas at 1360 Post Oak Blvd, suite 1410.

SonUSA inaugurated its current office at 1177 Enclave Parkway on October 11th 2002. The 40,000 square feet building with three floors was the first building built under direct support of an Angolan state company in a foreign country.
