| 520 | |a Practical Petrophysics, Second Edition, Volume 62 provides a comprehensive overview of building a petrophysical model. All aspects from the principles of data acquisition through analysis to reporting are covered. This is not intended to be a review of specific tools and measurements, nor is it simply a recipe book. The book aims to teach the fundamental principles that underlie the commonly used tools and techniques but also to encourage pragmatism and avoid reading too much into what is always imperfect data. | ||
