Über dieses Buch

This book primarily focuses on the principles and applications of electric logging, sonic logging, nuclear logging, production logging and NMR logging, especially LWD tools, Sondex production logging tools and other advanced image logging techniques, such as ECLIPS 5700, EXCELL 2000 etc. that have been developed and used in the last two decades. Moreover, it examines the fundamentals of rock mechanics, which contribute to applications concerning the stability of borehole sidewall, safety density window of drilling fluid, fracturing etc. As such, the book offers a valuable resource for a wide range of readers, including students majoring in petrophysics, geophysics, geology and seismology, and engineers working in well logging and exploitation.

Chapter 1. Introduction

Abstract

Well logging, as a terminology, is originated from France in 1927. Its primary meaning is electrical coring, which is a continuous record of characteristics of rock formations traversed by a measurement device in the well bore.

Chapter 2. Electrical Logging

Abstract

The resistivity of a substance is its ability to impede the flow of electrical currents.

Chapter 3. Sonic Logs

Abstract

Last chapter focused on formation resistivity, one is R _t, the resistivity of true zone; another one is RXO, the resistivity of flushed zone.

Chapter 4. Nuclear Logs

Abstract

In the preceding chapters, electrical devices are seen to respond primarily to the fluid content of earth formations.

Chapter 5. Nuclear Magnetic Resonance

Abstract

In this chapter, the nuclear magnetic resonance phenomenon and its principle are first introduced, and then the applications, including determining the porosity, permeability, and how to discriminate fluid type by using NMR logging, which are important in this chapter.

Chapter 6. Production Logging (PL)

Abstract

Production logging traditionally encompasses a number of well logging techniques that run on completed injection or production wells, with the goal to evaluate the well itself or the reservoir performance.

Chapter 7. Logging-While-Drilling (LWD)

Abstract

The crucial element in logging that has so far been covered up, is the wellbore and the drilling process that creates it. Although it is beyond the scope of this volume to discuss drilling, there are several aspects that merit mention in their relationship to logging.

Chapter 8. Rock Mechanics

Abstract

Rock mechanics is defined as “the fields of study devoted to understanding the basic processes of rock deformation and their technological significance”.

Chapter 9. The Advanced Well Logging Technology

Abstract

This chapter will present some advanced well logging system, which mainly includes the so-called image logging, such as Eclips-5700 of Baker Hughes, Exell-2000 of Halliburton, these two systems are briefly introduced.

Chapter 10. Integrated Interpretation of Well Logging Data

Abstract

Well logging, has become in some ways the geologist’s eye––an eye that is imperfect and sometimes distorted but nevertheless not blind––and an instrument for the reservoir engineer, occupies a special place and plays an important role in petroleum research by the economies that they bring and the amount of information they contain.
