Beginning with a discussion of the Earth's crust, common rocks and minerals, this book takes the reader step-by-step through the geologic aspects of petroleum exploration. It also discusses surfaces and susurface mapping and plate tectonics. In addition to exploration, the book provides details on drilling, including problems, techniques and evaluating/completing a well and, finally, production. As well as examining about exploration, drilling and production methods, the reader should also become familiar with basic language used in the petroleum industry.
