Page 10 - Well Logging and Formation Evaluation

INTRODUCTION

The purpose of this book is to provide a series of techniques which will
be of real practical value to petrophysicists in their day-to-day jobs. These
are based on my experience from many years working in oil companies.
To this end I have concentrated wherever possible on providing one rec-
ommended technique, rather than offer the reader a choice of different
options.
The primary functions of a petrophysicist are to ensure that the right
operational decisions are made during the course of drilling and testing a
well—from data gathering, completion and testing—and thereafter to
provide the necessary parameters to enable an accurate static and dynamic
model of the reservoir to be constructed. Lying somewhere between
Operations, Production Geology, Seismology, Production Technology and
Reservoir Engineering, the petrophysicist has a key role in ensuring the
success of a well, and the characterization of a reservoir.
The target audience for this book are operational petrophysicists in their
first few years within the discipline. It is expected that they have some
knowledge of petroleum engineering and basic petrophysics, but lack
experience in operational petrophysics and advanced logging techniques.
The book also may be useful for those in sister disciplines (particularly
production geology and reservoir engineering) who are using the inter-
pretations supplied by petrophysicists.
