Maersk Oil entered Angola in 2005 and has since made the Chissonga discovery, declared commercial in 2011, and the Azul discovery, which generated world-wide interest as the first positive deepwater presalt well in the Angolan analogue to the prolific offshore regions of Brazil.


Maersk Oil bought a 50% interest in the deepwater Block 16 in 2005 covering some 4,900 km2 and with water depths up to 1,500 metres. It currently holds a 65% interest, with partners state oil company Sonangol P&P (20%) and Odebrecht (15%).

In 2006, Maersk Oil entered into Production Sharing Agreements for Blocks 8 and 23 with an operated interest of 50%. Its partners are Sonangol (20%)


and Svenska Petroleum (30%).

The blocks lie in the offshore Kwanza basin and cover a combined area of 9,780 km2 with water depth in Block 8 up to 500 metres and in Block 23 up to 1,500 metres.

Maersk Oil discovered Chissonga, in Block 16, in 2009 and Azul, in Block 23, in late 2011. Mid 2012 another discovery was made in Block 16 with the Caporolo-1 well.

The first well in Block 8 with a presalt objective is scheduled for late 2013. Exploration and appraisal drilling will continue in 2013-2014.

Chissonga appraisal drilling activity is complete and a field development plan is being matured.

Maersk Oil submitted the Field Development Plan for Chissonga in 2013.


Maersk Oil’s use of advanced seismic technologies enabled the discovery of Chissonga in a block that had been extensively drilled by previous operators without success.

Maersk Oil has drilled eight deepwater wells offshore Angola since 2009.

In the Kwanza Blocks, Maersk Oil is the frontrunner in chasing the deepwater presalt play in the conjugate margin to Brazil.
