No references, but the amount of oil in the North Sea should be
indicative. The lack in Sweden could simply be a phenomenon of the
particular rock layers/thickness/fault structure. The science is really
too new and unexplored for this theory to generate a lot of supporting
evidence yet.
Even so, if oil is not being produced at depth all around the world, it
most certainly will tend to percolate from deeper reserves to more
shallow reserves over time, such that oil that is currently unreachable
eventually works its way up to fill previously evacuated salt domes.
