Synopsis

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.

About this title

From the Back Cover

Well logging has come a long way from the simple electrical devices of the early years. Today's tools are not only much more accurate but much more diverse in their applications. Among these are tools that characterize geological properties of rocks in the borehole in a way that was previously only possible with oriented cores. Thus, borehole imaging, nuclear spectroscopy, nuclear magnetic resonance, and paleomagnetic logging provide precise information about bedding, mineralogy, texture, and age of the rocks traversed by a borehole. Many of these logs can not only be acquired in the traditional "wireline" mode, but also in logging-while-drilling mode where the sensors are placed directly behind the drill bit, and the measurements are transmitted in real-time to the surface. Combined with new technology to drill deviated wells, the geoscientist now has tools which allow him to characterize 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.
