So you want to live in Houston, huh?
In case you don't, my old firm is in Oil, Gas and petrochem/chem consulting and design, and is not located in Houston.
They specialize in refineries, chemical plants, offshore rigs, pipelines and such.
I might be able to place a call to see if they're looking. It might take a few weeks, cause I hear they're having some problems in New Orleans and Mobile right now.
