I've been around for years but have never posted on this board. First learned about ERHE on the old Yahoo PGO board. I remember Platina and Mr.Crazy (IAintDrunk), and BSK were regular posters there too.
I have an idea that the clue:
rig(dwd) = jdz
means that the Deepwater Discovery is still in the JDZ.
Mr. Oilphant referenced correct answers to the rest of his puzzle, but not this part.
My PGO investment is up about 1000% from the dark days of bankrupcy. May this investment prove as profitable for all of us ERHE mushrooms (kept in the dark and fed bull&*#*)
