  log interpretation charts: Geological Well Logs S. Luthi, 2013-03-14 When I joined Schlumberger in 1982 I was surprised to find very few geologists in the company, and the few there were worked more as log analysts than geol ogists. The reason for this became soon clear to me: Except for the dipmeter there was no tool, and no other service, that was considered geological. Schlumber ger geologists were supposed to work with dipmeters, and, if they had a taste for it, the natural gamma-ray spectroscopy logs. It turned out that my timing was fortunate. At Schlumberger's research center, in Ridgefield, Connecticut, a prototype electrical imaging tool had been designed, and after having spent three years in the Middle East I was transferred there. The first field test results were just coming in, and the images were startling. We could see geological details that nobody had ever seen from a log: cross-beds, unconformities, pebbles, fractures, folds, faults. No cores were needed to confirm the reality of these data; they were too real to be artifacts.
  log interpretation charts: Finding Oil and Gas from Well Logs L.M. Etnyre, 2013-11-11 Several excellent books on weil log interpretation have already been published. However, I feel that these books do not place enough emphasis on the inherent uncertainties in tool responses or on the related and very practical problern of selecting suitable data points for statistical or quantita tive calculations. Thus, I have written this book not only to introduce the newcomer to this very complex art and science, but also to provide him or her with the necessary tools to produce better interpretations. The problems at the end of each chapter are essential to a more complete understanding of the subject matter and include many practical notes based on problems I have encountered in actual applications. This book emphasizes that you develop your own concepts and understanding of the underlying principles, rather than acquiring a compendium of knowledge based on certain rules of thumb. If you are to successfully interpret welllogs, you need to be able to apply your knowledge to new problems that may not follow the preconceived ideas and approaches you would follow if you approached weil log analysis from a cookbook standpoint.

  log interpretation charts: Well Logging Handbook Oberto Serra, 2008 Following the success of the Drilling Data Handbook, Editions Technip has designed this book to cover the well logging principles and its applications. This well logging handbook first edition starts with a summary on geology and petrophysics focusing mainly on its applications. The wide range of logging measurements and applications is covered through eleven sections, each of them organized into four chapters. All in all, this is a strongly-bound, user-friendly book with useful information for those involved in all aspects and applications of well-logging. The paging is notched and externally labelled alphabetically to allow a quick access.

  log interpretation charts: Theory and Evaluation of Formation Pressures EXLOG/Whittaker, 2013-03-09 The objectives of this book are: (1) to educate the prospective Pressure Evaluation Geologist to a basic level of expertise; (2) to provide a reference tool for the experienced geologist; and (3) to foster constructuve thought and continued development of the field geologist. Despite the incorporation of many new ideas and concepts, elaboration of the more re cent concepts is limited due to space considerations. It is hoped that the geologist will follow up via the literature referenced at the end of each chapter. Easy reference is provided by the detailed table of contents and index. A glossary of terms, definitions, and formulae adds to the usefulness of this reference text. ACKNOWLEDGMENTS FOR FIGURES Figure 2-7 is reprinted by permission of the AAPG from Barker, 1972.

No other books offer the breadth of information and range of applications available in this set.
  log interpretation charts: Well Logging for Earth Scientists Darwin V. Ellis, Julian M. Singer, 2008-06-18 The first edition of this book demystified the process of well log analysis for students, researchers and practitioners. In the two decades since, the industry has changed enormously: technical staffs are smaller, and hydrocarbons are harder to locate, quantify, and produce. New drilling techniques have engendered new measurement devices incorporated into the drilling string. Corporate restructuring and the graying of the workforce have caused a scarcity in technical competence involved in the search and exploitation of petroleum. The updated 2nd Edition reviews logging measurement technology developed in the last twenty years, and expands the petrophysical applications of the measurements.
  log interpretation charts: Standard Handbook of Petroleum and Natural Gas Engineering: Volume 2 William C. Lyons, 1996-10-16 Petroleum engineering now has its own true classic handbook that reflects the profession's status as a mature major engineering discipline. Formerly titled the Practical Petroleum Engineer's Handbook, by Joseph Zaba and W.T. Doherty (editors), this new, completely updated two-volume set is expanded and revised to give petroleum engineers a comprehensive source of industry standards and engineering practices. It is packed with the key, practical information and data that petroleum engineers rely upon daily. The result of a fifteen-year effort, this handbook covers the gamut of oil and gas engineering topics to provide a reliable source of engineering and reference information for analyzing and solving problems. It also reflects the growing role of natural gas in industrial development by integrating natural gas topics throughout both volumes. More than a dozen leading industry experts-academia and industry-contributed to this two-volume set to provide the best , most comprehensive source of petroleum engineering information available.

  log interpretation charts: Fundamentals of the Petrophysics of Oil and Gas Reservoirs Leonid Buryakovsky, G. V. Chilingar, Herman H. Rieke, Sanghee Shin, 2012-07-25 Written by some of the world's most renowned petroleum and environmental engineers, Fundamentals of the Petrophysics of Oil and Gas Reservoirs is the first book to offer the practicing engineer and engineering student these new cutting-edge techniques for prediction and forecasting in petroleum engineering and environmental management. In this book, the authors combine a rigorous, yet easy to understand, approach to petrophysics and how it is applied to petroleum and environmental engineering to solve multiple problems that the engineer or geologist faces every day. Useful in the prediction of everything from crude oil composition, pore size distribution in reservoir rocks, groundwater contamination, and other types of forecasting, this approach provides engineers and students alike with a convenient guide to many real-world applications. Petroleum geologists and engineers must have a working knowledge of petrophysics in order to find oil reservoirs and devise the best plan for getting it out of the ground, before drilling can begin. This book offers the engineer and geologist a fundamental guide for accomplishing these goals, providing much-needed calculations and formulas on fluid flow, rock properties, and many other topics that are encountered every day. The approach taken in Fundamentals of the Petrophysics of Oil and Gas Reservoirs is unique and has not been addressed until now in book format. Readers now have the ability to review the historic development of relationships and equations to define critical petrophysics attributes, many of which have either never been covered in the literature on petrophysics. Useful for the veteran engineer or scientist and the student alike, this book is a must-have for any geologist, engineer, or student working in the field of upstream petroleum engineering.
  log interpretation charts: Geophysical Well Logging Jay Tittman, 2012-12-02 Geophysical Well Logging is a three-chapter text that discusses the physics of well logging measurements. This book describes the techniques universally used in formation evaluation, including electrical, nuclear, and sonic techniques. Chapter 1 deals with the special features of logging measurements, tool design, and the relation between logging and coring. This chapter also examines the hostile downhole environment as basic sonde configurations and combination tools. Chapter 2 discusses elementary interpretation principles, the role of logging in formation evaluation, and the uninitiated to the motivation for the wide variety of measurements found in practice. Chapter 3 investigates the physics behind electrode and induction methods for measuring electrical resistivity, as well as the concepts of geometric factor, skin effect, focused measurements, and pseudo-geometric factor. It also considers significant topics on neutron transport and moderation and their application to neutron sonde design and logging measurements; gamma-ray transport and its application to density and photoelectric-absorption logging; methods for the measurement of gamma-ray spectra; and scintillation and germanium spectrometers. This chapter further explores the body and borehole waves of the sonic methods; waves in porous media; conventional interval-transit-time techniques; and full-waveform analysis methods. Physicists, chemists, and engineers who are interested in geophysical field-measurement methods will greatly benefit from this book.

  log interpretation charts: Developments in Geophysical Exploration Methods—3 A.A. Fitch, 2012-12-06 One of the themes in current geophysical development is the bringing together of the results of observations made on the surface and those made in the subsurface. Several benefits result from this association. The detailed geological knowledge obtained in the subsurface can be extrapolated for short distances with more confidence when the geologi cal detail has been related to well-integrated subsurface and surface geophysical data. This is of value when assessing the characteristics of a partially developed petroleum reservoir. Interpretation of geophysical data is generally improved by the experience of seeing the surface and subsurface geophysical expression of a known geological configuration. On the theoretical side, the understanding of the geophysical processes themselves is furthered by the study of the phenomena in depth. As an example, the study of the progress of seismic wave trains downwards and upwards within the earth has proved most instructive. This set of original papers deals with some of the more vigorous developments in subsurface geophysics: and it is hoped that it will contribute to the understanding of geophysical phenomena in the solid. The editor thanks the busy workers in the several fields who have made time to produce these contributions.

  log interpretation charts: Principles of Petroleum Reservoir Engineering Gian L. Chierici, 2013-03-09 Six years ago, at the end of my professional career in the oil industry, I left my management position within Agip S.p.A., a major multinational oil company whose headquarters are in Italy, to take up the chair in reservoir engineering at the University of Bologna, Italy. There, I decided to prepare what was initially intended to be a set of lecture notes for the students attending the course. However, while preparing these notes, I became so absorbed in the subject matter that I soon found myself creating a substantial volume of text which could not only serve as a university course material, but also as a reference for wider professional applications. Thanks to the interest shown by the then president of Agip, Ing. Giuseppe Muscarella, this did indeed culminate in the publication of the first Italian edition of this book in 1989. The translation into English and publication of these volumes owes much to the encouragement of the current president of Agip, Ing. Guglielmo Moscato. My grateful thanks are due to both gentlemen. And now - the English version, translated from the second Italian edition, and containing a number of revisions and much additional material. As well as providing a solid theoretical basis for the various topics, this work draws extensively on my 36 years of worldwide experience in the development and exploitation of oil and gas fields.

  log interpretation charts: Heat Contents of Some Green River Oil Shales R. L. Wise, R. C. Miller, H. W. Sohns, 1971 Heat content studies were conducted on burned shale, spent shale, and three grades of raw oil shale from the Green River Formation. Corrections were made for product enthalpies. The results were compared with previous work, indicating good agreement below retorting temperatures, but some differences at retorting temperatures. A general equatoin was developed relating heat content to oil-shale grade and temperature.
