Hello everyone!
I've been reading those threads covering the Oil & Gas industry, first of all, would like to say a BIG THANKS to all of you that have contributed to the thread, the feedback and opinion from all of you really opened my mind and gave me some insights into the Oil & Gas industry.

Coming from a non-technical background, a business degree, as I would like to study and explore more about the Oil & Gas industry, what kind of books/ reading materials that all of you would recommend me to go for? Or any other avenues that enables me to learn more about the industry?

Have been browsing through the Amazon website for some book on Petroleum Economics, and the followings are some books that come out in the top of the lists:

Petroleum Economics: Issues and Strategies of Oil and Natural Gas Production, by Rognvaldur Hannesson
An Introduction to Petroleum Technology, Economics and Politics, by J.G Speight
The Global Oil & Gas Industry: Management, Strategy and Finance, by Andrew Inkpen and Michael H. Moffett
Nontechnical Guide to Petroleum Geology, Exploration, Drilling and Production, by Norman J. Hyne
The Petroleum Industry: A Nontechnical Guide, by Charles F. Conaway

Some of those books, if not all, appear to me as text-book like reading materials, is there any good books out there about the industry that all of you can recommend for laymen?

Thank you!
