Targets: most everything ranked 8-14 in the T14, with Michigan being a reach and a few of them being reachy targets, if that makes sense.
However, you are very likely to get into University of Texas. You said you want to work for a Big Oil company, I'm assuming as General Council? Or do you mean a Big Law firm that specializes in defending Oil companies? At any rate, I would THINK U. Texas would actually have a huge advantage in this area, though I could be wrong. You should look into the hiring practices of "Big Oil" as you're calling it. I have a feeling not many Boalt grads go into that line of work, but I could be stereotyping too much.
