Content Description top ↑

The aim of this monograph is to indicate the state of the art of Induced Polarization (IP) after more than 15 years of commercial use.

The main source of information consists of books and papers in scientific journals, as well as verbal communications made during scientific meetings and symposia, not forgetting our own experience. We have quoted in the bibliography a large number of items; furthermore, we have tried to give a short account of the ideas of some prominent authors. Of course, we could not help expressing our own ideas. Besides indicating the views of others, we had to comment on them and add any materials that we deemed relevant to the subject. An important item is the comparison of theory with experimental evidence. We shall see how much work there is still to be done to correlate them satisfactorily. The book consists of two parts. The second part is dedicated to theory. A physical theory is never a simple revelation; all the known truths we rely on are the result of painstaking collection and systemization of experimental facts.
