Sorry, I can't help you with Tidelands. I prefer oil over natural gas, too much development taking place in North America will keep prices low for a long time relative to oil. You might check out TGP, a liquified natural gas tanker co. I may open a position tomorrow. Japan's energy problems are easiest solved with natural gas and there is a shortage of tankers currently. I have owned Teekay Shipping in the past and done well, this is one of their subsidiaries. Oil tankers are over supplied now.
I am sitting on a ton of cash waiting for stocks like TGP to go on sale.
