Angola\'s Block 17 has proven prolific for partners in the offshore license, with Girassol and Dalia already producing, Pazflor in development, and the CLOV project in consideration. Located approximately 90 miles (150 kilometres) offshore Angola in ultra-deep waters, the Pazflor project incorporates four fields -- Perpetua, Zinia, Acacia and Hortensia -- spanning 148,263 acres (600 square kilometres) on the eastern edge of Block 17.
Fields
First of the Pazflor cluster to be discovered, and the 10th field discovered on Block 17, Perpetua is located about 124 miles (200 kilometres) northwest of Luanda in 2,608-foot-deep (795-meter-deep) water. The Perpetua-1 exploration well discovered the field in August 2000, showing a daily flow rate of 8,740 bopd of 20-degree API in production tests. Discovered in December 2002, the Zinia field was the 13th field encountered on Block 17 and the second of the Pazflor project. Located 90 miles (150 kilometres) from the Angolan coast, Zinia is situated in a water depth of 2,356 feet (718 meters). Also on the eastern portion of the license, the Zinia-1 well tested a flow rate of 3,650 bopd. The discovery of the next two fields made the Pazflor project a commercial viability. The Acacia discovery followed in the spring of 2003 in water measuring 3,379 feet (1,030 meters). The Acacia-1 discovery well tested a combined 13,712 bopd from two separate zones, including Oligocene. The last to be discovered of the four eastern Block 17 fields, Hortensia is located 6 miles (10 kilometres) north of the Acacia field in waters measuring 2,723 feet (830 meters) deep. Tested at 5,092 bopd, the Hortensia-1 well was also discovered in the spring of 2003.
Field Development
Gathering oil from all four fields at water depths ranging from 2,000 feet (600 metres) to 4,000 feet (1,200 metres), the Pazflor integrated field development linked subsea wells through subsea production lines, injection lines and risers to an FPSO. Approved by authorities in late 2007, field development called for drilling to commence in 2009 and facility installations to commence in 2010. Pazflor production commenced Aug. 26, 2011, bringing production rates for Block 17 to 700,000 bopd.
The Pazflor FPSO is currently under construction in South Korea and will be the first of its kind to process two very different grades of oil. Nearly 120,000 metric tons of steel will be used in the construction of this leviathan, one of the largest FPSOs ever built. The onboard equipment includes gas turbines rated at a record 120 MW - enough to supply a city with some 100,000 inhabitants. The FPSO, Total’s third on Block 17, will be able to process 220,000 barrels of oil per day and store 1.9 million barrels.
