DL Abstract

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.

DL Abstract

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.

The relatively recent, very large discoveries offshore Brazil have put pre-salt exploration in the South Atlantic back in the foreground. Pre-salt exploration history, however, is far more ancient and marked with some major successes – but also many failures. Here’s a brief overview of this exploration in West Africa until the M’Boundi discovery, which will be described in detail as it brings some lessons that readers can discover for themselves.

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.

Since establishment of AAPG Africa in 2000, the Region’s leadership teams over the years have shown strong commitment and passion toward the Association achieving its goals for the region. Their dedicated efforts have resulted in not only an increased awareness of AAPG, but also steady growth of the Region’s membership, from 450 in 1999 to over 3,060 in June 2014.
