If I know everything there is to know about O&G, what do I know?

Say I walk into an interview at a buy-side firm and tell the interviewer that I know the oil and gas industry pretty well. What should I know besides industry news, familiarity with many companies, a stock pitch or two, and obviously how to value companies in the industry?

I'm interested in oil and gas, and I know it about as well as any other industry, but I wouldn't call myself an expert by any stretch. I have a number of interviews coming up in January, so I'd like to spend the next month and a half really nailing down my knowledge on this industry. I have relatives and family friends that work in the industry, so I can get just about any information I want if I know what to ask for.
