Pre-salt (Aptian) lacustrine shales are the primary source rocks that charge late Cretaceous and Tertiary reservoirs in the petroliferous (15 billion barrels of oil recoverable) Campos Basin. As a result, an understanding of salt weld timing is a critical component in assessing charge risk and high-grading deep-water play fairways. The traditional method of assessing regional structural timing with isochron maps, although useful, often yields erroneous results when weld timing is being ascertained. Mini-basins that have welded and display onlap stratal geometry at their margins may have the same isochron map pattern as actively subsiding basins which have growth wedge...
