Stoneley's book is a good beginner's guide to the facinating world of finding and evaluating oil and gas. The book is written with clarity and has copious illustrations. It is written for non-geologists. What this means is that it is written by exploration geologists. Hence, sometimes there is more geological detail provided than necessary and perhaps not enough engineering detail. For example, the drilling and logging section could be beefed up. Nevertheless, as an introductory text I feel the extra detail on some aspects of geology issues is a bonus and that the engineering detail is more than sufficient. This text accompanies the eponymous JAPEC training course. See [...] for details.
