f Seismic And Sequence Stratigraphy As An Aid To Hydrocarbon Exploration In The Bredasdorp Basin, Southern Offshore

Seismic stratigraphy using sequence-stratigraphic<br>concepts as developed by Vail and others has been<br>applied at Soekor to provide an overall<br>stratigraphic framework for the Bredasdorp Basin.<br>This method was first applied to the drift<br>succession and later to the synrift succession. The<br>synrift has been broken down into 4 sequences and<br>the drift into 21 Sequences. In the synrift<br>succession the greatest reservoir potential is in<br>the transgressive and early highstand tracts whereas<br>in the drift succession the greatest reservoir<br>potential is in lowstand tracts.The distribution<br>of source rocks and regional sealing shales can also<br>be predicted using the seismic-stratigraphic framework.
