http://www.offshore-mag.com/Articles/Article_Display.cfm?

Article_ID=242632Located in shallow water offshore Kwanza basin adjacent to the city of Luanda. More than 95% of the block has water depth less than 200 m. Eight wells have been drilled, including the Cegonha-1 and Pardal-1 oil discoveries. Oil gravity is 17° to 18° API. Estimated remaining reserves are more than 500 MMbbl

Block 6 covers an area of 4.930 square kilometers and is also located in the northern area of Kwanza Basin offshore Angola. The water depth ranges from 50 meters to 500 meters. Block 6 was first licensed to Total.

After being further developed by Conoco and Sonangol, it will now be operated by Petrobras. Eight wells have been drilled by the previous operators, which resulted in 2 heavy oil discoveries. The largest of the discoveries is the Cegonha heavy oil field, which according to Sonangol contains 135 million barrels of oil.

The discovery of heavy oil in two wells gives rise to optimism, as the new operator has extensive experience in the development of such fields. A 3D survey has now been acquired over the Cegonha field and additional 3D will be acquired in Block 6.

InterOil's share of the signing fee for the two blocks ( 5and 6 ) amount in total to US $24.75 million. The working program for the partners in Blocks 5 & 6 over the next 4 years include drilling of 2 exploration wells in each block and shot or acquire existing 3D seismic in total of 2,200 square kilometers. InterOil's share of the working program will cost approximately US $25 million.

First licensed to Total in 1980. Four exploration wells were drilled of which one, Cegonha, made a heavy oil find. The company relinquished the block in 1984. Conoco signed a new licence in 1991 and relinquished in 1994 after four unsuccessful wells.
