Two decades ago, the first edition of this book demystified the process
of well log analysis for students, researchers and practitioners. Since
then, the industry has changed enormously: technical staffs have been
slashed, and hydrocarbons have become increasingly harder to locate,
quantify, and produce. In addition, new techniques of drilling have
engendered a whole new family of measurement devices incorporated into
the drilling string. Petroleum deposits are becoming scarce, while
demand steadily increases. Massive corporate restructuring and the
"graying" of the workforce have caused the technical competence involved
in the search and exploitation of petroleum to become scarce. In this
comprehensive update, the authors include all of the new logging
measurement technology developed in the last twenty years and expand the
petrophysical applications of the measurements. In sum, this is a
thoroughly revised graduate level textbook, as well as a useful handbook
for any practicing earth scientist.
