I disagree with your thoughts.
The perth basin becomes coarser and deeper as you go east.
The hydrocarbon pathway means that it is filled to spill and the spill goes west together with finer sands and also clay which fills the crevices between the sand particles.
LD2 which is west and south of LD1 will be higher yielding, IMHO, than LD1 and may contain a greater oil content .... but the drill bit will do the talking.
The BOD have destroyed their individual credibility for any future directorship in my opinion.
I have been a long term supporter of these individuals but I am reassessing my opinion.
