Well Logging - Data Acquisition and Applications

Description

This book explains in detail all the physical principles on which are based the logging tools Wireline (WL) and Logging While Drilling (LWD). It describes as well the fundamental tools of the principal service companies, focusing on the factors that influence measurement and on the main applications in geology, geophysics, and petrophysics. As such it constitutes a reference document for all geologists and engineers involved in petroleum exploration and field development. Content: Front Matter • Table of Contents 1.
