Thanks for those replies TradeSwapper.
On the question of challenges in the oil industry, I was thinking more the technological challenges, drilling deeper, supporting massive weights from floating platforms, doing what was impossible a few years ago, those were the challenges I was thinking of.
Back when USA worked to get men to the moon, there must have been much excitement and a pioneering spirit amongst the engineers, maybe a feeling that any challenge could be overcome.
I agree with deep sea sector growth regardless of fluctuations in oil prices, there are too many billions of people that have seen
life with petroleum and they want it too. There is no turning back.
