Abstract:We can predict the lithology variation of horizontal formations by analysing the variation of the ratio of two neighbouring bed stacking velocity contrast to their vertical travel time difference,i.e.(Vn-Vn-1)/(t0n-t0n-1).Combining this with drilling data,we can even determine sand and shale percentage contents.This method is simpler than the interval velocity method used to determine lithology and the percentage contents of sand and shale.
