Publisher's Synopsis
The aim of this collection of four articles is to demonstrate some little-known or unknown applications of acoustic logging for characterizing reservoirs. Acoustic logging gives a geometric description of the well environment by refraction and reflection imaging and gives a good picture of the fractured medium.;The first three articles show how acoustic logging can be used to describe the near-well reservoir medium. The last article is devoted to analyzing dispersive modes of the Stoneley type and of the flexural type.
