Hungo

Hungo Oil Field Profile

Location and Geology

• The Hungo Oil Field is located offshore in Angola, specifically within Block 15. The coordinates are approximately -6.309, 11.092 (WGS 84).
• The field is part of the Kizomba A Oil Project and is situated in water depths of 1,000 to 1,400 meters.

Discovery and Development

• The Hungo Oil Field was discovered in 1998 as part of a wildcat drilling program conducted between 1997 and 1999. This program resulted in six discoveries, including Hungo, Chocalho, Kissanje, Dikanza, and two other fields.
• The development of the Hungo and Chocalho fields was undertaken as part of the Kizomba A deepwater project, which began construction in 2001. The project involved the use of a tension-leg platform (TLP) and a Floating Production, Storage, and Offloading (FPSO) vessel.

Production

• Production at the Hungo Oil Field commenced in August 2004, with an initial production rate of more than 130,000 barrels per day (bpd). The target production rate for the Kizomba A project, which includes both Hungo and Chocalho fields, is 250,000 bpd.
• As of the latest data, the field is producing approximately 126,000 to 130,000 barrels per day.

Reservoir and Reserves

• The reservoirs at Hungo are from the middle to lower Miocene age, consisting of turbidity debris flows deposited along the upper/mid-slope. The structural trap configuration is controlled by early-Aptian salt movement and lateral channel seals. The wells have penetrated multiple high-quality reservoirs, resulting in an oil column exceeding 1,000 meters.
• The Kizomba field complex, which includes Hungo, has recoverable reserves approaching two billion oil-equivalent barrels.

Infrastructure

• The Kizomba A project features an ABB-designed 58,000-ton dry tree TLP and subsea completions tied back to the FPSO. The FPSO was built by Hyundai Heavy Industries at a cost of more than $800 million. The total project development involved an estimated investment of $3.2 billion.
• By the end of 2008, Kizomba A had 29 production wells and one development well.

Operators and Ownership

• The Hungo Oil Field is operated by ExxonMobil, which holds a 40% equity interest. Other partners include Eni S.P.A. (20%), BP (26.67%), and Statoil (now Equinor, 13.33%).

Crude Oil Characteristics

• The crude oil produced from the Hungo field is known as Hungo Blend. It is a medium density, medium sulfur crude oil with an API gravity of 28.3° and a sulfur level of 0.64 mass%. The nominal cargo size is 950,000 barrels with a 2-day lifting period.

Economic and Social Impact

• The Kizomba A project, including the Hungo field, has significant economic implications for Angola. The project has involved substantial investments and has contributed to the country's oil production. However, Angola has been facing challenges in maintaining oil production levels due to underinvestment and technical issues.

In summary, the Hungo Oil Field is a key component of the Kizomba A Oil Project in Angola, characterized by deepwater production, significant reserves, and advanced infrastructure. It plays a crucial role in Angola's oil industry and contributes to the country's economic landscape.
