Oli,
I was mumbling in particular about bright flat spots, as there not many horizontal rocks in the seismic that I have seen for the WPL/HDR data off Africa.
As I said some would say that I telling them to suck eggs, but was mainly aimed at giving the general punter a bit of an understanding.
Also as you indicated not all DHI's mean the same thing!, and that was the main gist of my point.
Luv your input Oli keep it up.
