As a new invester, can someone suggest a suitable book or reference manual or white paper for investors in oil and gas. This is new and although a risk taker.....want to add some expertise on how to win....determine SP and value and when to get out!

I currently have investments in MEO, AUL, African oil, Range Resources, Bayou Bend, Pearl, junex, and 2 banks QZZ and Amnsf.

Thanks in advance
