Geology

Well it's what I do for a living I suppose. Not that there's too much to it. I used to use this book whenever I came across something I wasn't sure of but after a few years of experience I've realised no geologist knows what they're talking about but the good ones are very convincing nonetheless. It appears the recipe to success therefore is to appear knowledgeable and use wikipedia judiciously. How we ever find any oil i'll never know :)
