Exxon Mobil Corporation (NYSE:XOM) affiliate Esso Exploration Angola (Block 15) Limited (Esso Angola) is celebrating 15 years of safe and successful operations in Angola. Esso Angola and its venture partners in Block 15 have worked with the government of Angola to maximize the value of the country’s resources, creating long-term benefits for the Angolan people.

The block surpassed one billion barrels in cumulative production in September and is currently producing over 600,000 barrels of oil per day. It is currently the single largest producing block in the country, and since 1994, the company and its co-venturers have announced resource discoveries totaling nearly 5 billion oil-equivalent barrels.

“We are proud of Block 15’s impressive record of safe, reliable operations and its contribution to economic development in Angola,” said Andy Swiger, senior vice president for ExxonMobil. “We look forward to our continued partnership with the government of Angola and to being a part of the country’s very promising future.”

Esso Angola has applied world-class technologies to move Block 15 hydrocarbon development from front-end engineering and design to production as quickly and cost-effectively as possible. This included the installation of five massive floating production, storage and offloading vessels (FPSOs), two wellhead tension leg platforms, and a complex network of subsea components. It also involved significant technical training, development and jobs for Angolans and the purchase of local goods and services.

Continued oil development in Block 15 is progressing, and a project to deliver associated gas from oil production to the Angola LNG development is under way.

Esso Angola contributes to community health, education, and infrastructure projects across Angola. Over the past five years, Esso Angola, Block 15, and ExxonMobil have invested more than U.S. $40 million in support for health-care programs that combat the spread of malaria and HIV/AIDS. Other programs support educational and vocational-technical training opportunities for women and girls in Angola. The Esso Angola health-care and education programs earned recognition from the U.S. State Department in 2008. Additionally, Esso Angola, Block 15 and the ExxonMobil Foundation support a project to help protect the Giant Sable Antelope, which until a few years ago was believed to be extinct.

Esso Exploration Angola (Block 15) Limited is the operator of Block 15 with 40 percent interest. The other co-venturers are BP Exploration (Angola) Limited (26.67 percent), ENI Angola Exploration B.V. (20 percent) and Statoil Angola Block 15 A.S. (13.33 percent). Sonangol E.P. is the concessionaire.
