Brazillian Discoveries Dominate Cape Town Meet

 By Tako Koning, Luanda, Angola

Some of the best attended presentations at the most recent international convention of geoscientists were those on the recent pre-salt oil and gas discoveries in Brazil.

With newly discovered fields such as the Tupis field having estimated reserves of eight billion barrels oil, many explorationists could not help but speculate on the importance of this play on the presalt basins which are on the conjugate margins along the coast of West Africa from Gabon down to Namibia.

This pre-salt play may be especially relevant to Angola where the pre-salt sag basin is both extensive and has barely been penetrated by the drill bit.

Approximately 1,700 registrants from all over the globe were present at the 2008 International Convention and Exhibition of the American Association of Petroleum Geologists (AAPG), held October 26-29 2008, in the beautiful South African city of Cape Town.

For anyone focused on Africa oil and gas exploration and production, Cape Town was the place to be.

The theme of this conference was “African Energy: Global Impact”. An extensive programme of oral and poster paper presentations were held based on the following themes:

Deepwater Reservoir Systems – A Global Perspective, “Global Advances in Geosciences Next Generation Tools and Techniques, The New Business of Energy; Global Coal, CBM, Gas Hydrates, C02, Remediation Gondwana and Pangean Petroleum Systems: Africa, Middle East, South Atlantic, Caspian, Mediterranean, Arctic and Asia-Pacific. A wide variety of pre-conference and post- conference geological field trips were held in the general Cape Town area as well as further away to the Karoo Basin of South Africa and the Zerrissene Turbidite System in southern Namibia. One of the outstanding opportunities at this particular conference was for geoscientists to be able to view approximately 450 meters of turbidite drill cores from South Africa and Angola. PetroSA provided representative cores of all sedimentary facies from the Bredasdorp Basin, offshore South Africa. TOTAL and Chevron were able to obtain Angola government approval as well as their partners’ approvals to show many meters of turbidite channels cores from deepwater Blocks 17 and 14.

The 2009 AAPG International Convention and Exhibition will be held in November in Rio de Janeiro. All indications are that an equally interesting and extensive array of presentations and field trips will be available to the attendees in Rio, 2009.
