PREFACE
The relentless search for elusive hydrocarbon reserves demands that geologists and reservoir engineers bring into play more and more expertise, inventiveness and ingenuity. To obtain new data from the subsurface requires the continual refinement of equipment and techniques. This book describes! the various well-logging equipment at the disposal of geol
