The results of regional deep seismic acquisition in the South Atlantic continental margins have shed new lights on the birth and development of sedimentary basins formed during the Gondwana breakup. Recent models of mantle exhumation as observed in the deep water Iberian margin have been applied extensively to the interpretation of several basins in the Eastern Brazilian and West African conjugate margins. However, the tectonic development of these basins is markedly different from the magma-poor margins, and in this lecture we emphasize the contrasts from the tectono-sedimentary features imaged in deep-penetrating seismic profiles that extend from the platform towards the oceanic crust, which indicate that the Red Sea constitutes a better analogue for the birth of divergent continental margins.

Offshore Angola has to date delivered recoverable reserves in excess of 20 billion barrels of oil equivalent. This has been encountered in two distinct play systems: the Upper Cretaceous Pinda carbonates sourced by Lower Creatceous lacustrine mudstones and Tertiary deepwater slope turbidite sands sourced by underlying Upper Cretaceous marine mudstones. An extension of the Girassol play into Block 18 to the south will be used to describe how high quality 3D seismic data coupled with a detailed analysis of rock properties led to an unprecedented 6 successes out of 6 wells in the block, including the giant Plutonio discovery. Industry is turning once more to the carbonate play potential - this time in deepwater. It would seem that the Angola offshore success story is set to continue for some time to come.

Explorer Historical Highlight
It was a milestone year for everyone living in Angola. In 2002, Jonas Savimbi, the leader of the rebel group UNITA, was killed on Feb. 22 that year, bringing an abrupt end to the long and horrible 27 years civil war.

Explorer Making a Difference
Second time around: Award-winning AAPG geologist Tako Koning already had one successful career as an explorationist in Angola, and now he’s back for more – and helping residents there to recognize and appreciate the country’s geologic splendor.
