This revised and rewritten edition presents an account of the various open-hole log tools and the data they generate. In particular, it provides a comprehensive geological interpretation of the derived data enabling the geologist to capitalize fully upon well data.

Borehole geophysics is frequently applied in hydrogeological environmental investigations where, for example, sites must be evaluated to determine the distribution of contaminants. It is a cost-effective method for obtaining information during several phases of such investigations. Written by one of world's leading experts in the field, A Practical Guide to Borehole Geophysics in Environmental Investigations explains the basic principles of the many tools and techniques used in borehole logging projects. Applications are presented in terms of broad project objectives, providing a hands-on guide to geophysical logging programs, including specific examples of how to obtain and interpret data that meet particular hydrogeologic objectives.

This hand guide in the Gulf Drilling Guides series offers practical techniques that are valuable to petrophysicists and engineers in their day-to-day jobs. Based on the author's many years of experience working in oil companies around the world, this guide is a comprehensive collection of techniques and rules of thumb that work.The primary functions of the drilling or petroleum engineer are to ensure that the right operational decisions are made during the course of drilling and testing a well, from data gathering, completion and testing, and thereafter to provide the necessary parameters to enable an accurate static and dynamic model of the reservoir to be constructed. This guide supplies these, and many other, answers to their everyday problems. There are chapters on NMR logging, core analysis, sampling, and interpretation of the data to give the engineer a full picture of the formation. There is no other single guide like this, covering all aspects of well logging and formation evaluation, completely updated with the latest techniques and applications.·A valuable reference dedicated solely to well logging and formation evaluation.·Comprehensive coverage of the latest technologies and practices, including, troubleshooting for stuck pipe, operational decisions, and logging contracts.·Packed with money-saving and time saving strategies for the engineer working in the field.

Logging has come a long way from the simple electrical devices of the early years. Today's tools are considerably more accurate and are used for an increasingly diverse number of tasks. Among these are tools that characterise geological properties of rocks in the borehole. Combined with new technology to drill deviated wells, the geoscientist now has tools which allow him to characterise and develop reservoirs more accurately than ever. This book, written for researchers, graduate students and practising geoscientists, documents these techniques and illustrates their use in a number of typical case studies.
