The Kissanje Oil Field is located offshore Angola, specifically within Block 15, approximately 215 miles northwest of Luanda and 145 km west of Soyo.
The field is situated in water depths of 3,300 to 3,400 feet (around 1,006 to 1,036 meters).
Project Details
The Kissanje Oil Field is part of the larger Kizomba B Oil Project, which also includes the Dikanza Oil and Gas Field.
The project was developed by a joint venture consisting of ExxonMobil (operator, 40%), Eni S.P.A. (20%), BP (26.67%), and Statoil (now Equinor, 13.33%).
Discovery and Production
The Kissanje field was discovered in 1998 as part of a wildcat drilling program that resulted in several discoveries within the Kizomba complex.
Production from the Kissanje field commenced in July 2005.
The field is expected to recover approximately one billion barrels of oil, with a target production rate of 250,000 barrels per day (b/d).
Infrastructure
The Kizomba B project includes a surface wellhead platform and subsea wells tied back to a Floating Production, Storage, and Offloading (FPSO) vessel.
The FPSO has a storage capacity of 2.2 million barrels of oil, measures 285 meters by 63 meters, stands 32 meters tall, and has a weight of 81,000 tons. It can accommodate 100 personnel.
Crude Oil Characteristics
The Kissanje Blend crude oil is a medium-density, low-sulfur crude.
API gravity: 30.7°
Sulfur level: 0.36 mass%
Acidity: 0.54 mg KOH/g
Nickel: 10.7 mg/Kg
Viscosity at 20°C: 0.41 cst (for lighter fractions), varying with different cuts
The crude has a distillation yield profile that includes:
C1 to C4: 1.33% wt
Naphtha: 16.53% wt
Kerosene: 13.11% wt
Gas Oil: 15.96% wt
Atmospheric Residue: 53.08% wt
Production and Reserves
As of the data available, the Kissanje field was producing around 150,000 barrels per day (kbd).
The Kizomba B project, which includes Kissanje and Dikanza, is expected to recover approximately one billion barrels of oil.
Environmental and Social Impact
The development of the Kizomba B project involved significant investment in local goods and services, including contracts for in-country fabrication, logistics support, and training and development of Angolan personnel.
Operational Timeline
