An indispensable tool, this book introduces the three primary phases of well-logging technology to engineering and geosciences students. This text offers an in-depth study of the electric, radioactive, and acoustic properties of sedimentary rocks. Mathematical and empirical models relate a formation property of interest to the property measured with the logging tool. Openhole logging techniques are covered, along with concepts of traditional and modern tools.

Contents: Electrical resistivity of rocks • Radioactive and acoustic properties of rocks • Measurement environment • Resistivity logs • The spontaneous potential log • Gamma ray, neutron, and sonic porosity logs • Conventional interpretation techniques • Reconnaissance and pattern-recognition interpretation techniques • Log interpretation of shaly formations • Evaluation of gas-bearing formations
