This Reference Manual and Short Course cover all topics needed to understand log data acquisition and logging tool concepts for both open and cased hole logs: basic physics and operating concepts, focusing, or lack of it, on older log suites, example of log displays, and how to identify each curve, how to read logs (e.g. bed boundaries, which log curve is best to use) and much more.

QUICK FACTS:
RF-04: 152 pages, 14 chapters, detailed table of contents, computer-ready math.

RF-04S: as above PLUS 2 narrated video slideshows.

RECOMMENDED FOR: all geoscientists, geotechs, engineers, managers and CEO's.
