It's looking like the Bakken is due to slow up soon. Classic Austrian Boom, Fed prints the money and people over invest. We've flooded the markets with oil and the WTI is dropping. Last I checked it was around $85. Good news for the consumer.
Right now things are still cranking, but I expect that to change. I've started talking to people about my next hitch.
If you have been considering breaking in to the oil industry, my guess is that the next big investment boom will be LNG -- liquified natural gas. Louisiana supposedly two going on, at Cameron/Sabine Pass, and Lake Charles. Texas will get one at Freeport. Maryland of all places has one around Baltimore. And I think the PAC Northwest is getting one.
The other big areas are fertilizer plants (big one going up in Iowa), and petrochemicals, especially ethylene crackers. The last is probably the most risky as a softening economy will hurt the demand for plastics. I really like LNG, because as natural gas prices go lower, they will print money exporting to Europe. And Europe needs the gas.
