East Africa Margin Potential
The poster "New Petroleum Exploration Concepts Related to the Davie Fracture Zone, Offshore East Africa," by D.C. Rusk and Robert Bertagne, will be presented at the AAPG International Conference and Exhibition, set Sept. 21-24 in Barcelona, Spain.
The poster is one of nine to be presented in a Tuesday afternoon session, co-chaired by Bill St. John and G. Tari, on "Exploration Frontiers: East Africa, One of the Last Unexplored Passive Margins."
Other posters in the session include:
- "Frontier Exploration in East Africa - Beyond Seismic."
- "The Evolution of the East Africa Passive Margin and Petroleum Systems."
- "Tectonics of the Western Indian Ocean."
- "Salt Tectonics and Basement Structure in the Majunga Basin, Offshore Madagascar, as Revealed by New Shipborne Gravity and Magnetic Data."
- "Hydrocarbon Potential of Western Madagascar."
- "East Africa And Western India: Passive Margins from the Evolution of a Complex Ocean."
- "The South African East Coast: Evidence for an Active Petroleum System within the Tugela Fan, Durban Basin."
- "Basement Controls on Structure and Sedimentation in the Offshore Zambezi Delta Region."
The hosts for the AAPG meeting is the Institut Cartográfic de Catalunya (DPTOP).
The meeting will offer more than 500 papers and posters around the theme "Crossroads of Geology, Energy and Cultures."
The pre-registration deadline is Aug. 15, and attendees can register online.
East Africa Offshore Study Conducted in Three Phases
The offshore East Africa study by Bertagne and Rusk, in partnership with TGS-NOPEC Geophysical Co., was conducted in three phases:
• The first phase included a comprehensive evaluation of the petroleum systems, including play characteristics with emphasis on structural trends, leads and prospects.
• The second phase addressed the reprocessing of selected seismic lines to enhance the quality of the data and gain additional knowledge of relevant aspects of the stratigraphy and structure.
This was independent of the initial phase and was jointly conducted by TGS-NOPEC and Rusk, Bertagne & Associates.
• The final phase consisted of four sub-phases to map the major structural trends delineated in the initial part of the work.
A total of 33,000 kilometers of seismic control will be available for this phase, and additional selective 2-D reconnaissance seismic already has been acquired, processed and interpreted.
The completion of phase three is contingent on industry demand and ratification of boundary agreements between the neighboring countries and approval of the seismic acquisition programs by the host governments.
