dc.description.abstract | The second edition of Petroleum Geoscience is an updated and corrected version of
the first edition from 2010 and there are also four new chapters.
Petroleum geology and geophysics are not well-defined academic subjects. They
include many different aspects of the Earth sciences which are used in petroleum
exploration and production.
Nearly all types of insight can in some cases be useful in petroleum exploration
and production, but there are some disciplines that are most relevant. Since
petroleum is formed and for the most part hosted in sedimentary rocks, sedimentology
is critical. Palaeontology is important for dating rocks, and carbonate
reservoirs may consist mostly of fossils. Structural geology and basin analysis
are also vital for reconstructing the migration and trapping of petroleum. Geochemistry
and petroleum chemistry are also important. About 50% of the geoscientists
in the petroleum industry are involved with production rather than
exploration and we have added a chapter on reservoir modelling written by experts
from Statoil Norway.
Geophysical methods are essential for logging and seismic exploration, and
recently electromagnetic methods have also been more commonly used in exploration
and production. This is covered in a new chapter. We have also added a chapter
on CCS (Carbon Capture and Storage). The chapter on well logging has been
rewritten and is now more comprehensive.
Most universities do not offer specific courses in petroleum geology/geophysics
and only a few have Masters or PhD programmes in this field. Oil companies
therefore recruit many geologists with little training in these subjects.
In this book, we have tried to give a basic introduction to disciplines relevant to
petroleum exploration and we have also included some aspects of petroleum production
and modelling.
Since so many different disciplines are included in this book, it is clear that it has
not been possible to make in-depth treatments of all of these. This book provides a
relatively condensed and precise presentation of the basic theories and facts in each
subject and it was therefore necessary to limit the number of field examples and
cases | en_US |
