Preface
This book has been prepared by the collaborative effort of two somewhat separate technical groups: the researchers at the Institute for Petroleum and Organic Geochemistry, Forschungszentrum Jiilich (KFA), and the technical staff of Integrated Exploration Systems (IES). One of us, Donald R. Baker, from Rice University, Houston, has spent so much time at KFA as a guest scientist and researcher that it is most appropriate for him to contribute to the book. During its more than 20-year history the KFA group has made numerous and significant contributions to the understanding of petroleum evolution. The KFA researchers have emphasized both the field and laboratory approaches to such important problems as source rock recognition and evaluation, oil and gas generation, maturation of organic matter, expulsion and migration of hydrocarbons, and crude oil composition and alteration. IES Jiilich has been a leader in the development and application of numerical simulation (basin modeling) procedures. The cooperation between the two groups has resulted in a very fruitful synergy effect both in the development of modeling software and in its application.
The purpose of the present volume developed out of the 1994 publication by the American Association of Petroleum Geologists of a collection of individually authored papers entitled The Petroleum System - From Source to Trap, edited by L.B. Magoon and W.G. Dow. The idea was to describe the "petroleum systems approach" and thereby to "provide a mechanism for evaluating migration from active source rock to the trap". In 1984 when my colleague and friend Bernard Tissot and I published the second edition of our book Petroleum Formation and Occurrence (Springer-Verlag), we wrote in the preface that in the geosciences "computer modeling is here to stay." As an intellectual result we expected a "better chance for a much-needed synthesis of the principal fields in geosciences such as geology, geophysics, and geochemistry." Both of these volumes aspired to serve the same purpose: to understand interrelated processes of petroleum generation, migration, and accumulation and to put these in the perspective of the geological framework of basin evolution.
VI Preface
Although substantial progress has been made along these lines, there is still room for further advances and for more synergy. The present volume strives to generate more synergy among the various fields of the geosciences and to improve the methodology for a holistic approach in petroleum exploration and production. It is clear that this book cannot be the "last word" about what is a very complex subject. Instead we treat only a few of the major topics and questions in detail. The book is thus considered as a mosaic of important building blocks bringing together the evolution of petroleum and the geological framework of the dynamics of sedimentary basins. Basin modeling occupies an important place in this context.
We foresee that earth scientists in general will be attracted by the philosophy and approach presented in this book. It paves the way for combining the insight and views into the subsurface provided by modern seismic, advanced interpretation and visualization, with the understanding and results from an online interactive basin modeling capability. This combination certainly helps to unravel complex geological processes during basin evolution and permits a more rigorous and quantified assessment of a basin as a whole. For the same reasons we also expect petroleum explorationists to benefit substantially from the book.
In addition, we hope that organic geochemists will gain considerable new insight from our treatment of the current set of geochemical data coupled to the dynamic aspects of basin history. Geochemical data and interpretation results, such as those on source rock maturity and petroleum generation and expulsion, can now be extended in their application from single boreholes to entire regions by means of basin modeling. The direct coupling of basin models with seismic data bases will bring a new and exciting dimension to geochemistry in the not-too-distant future.
The authors want to take this opportunity to express their grateful thanks to the managerial, technical and secretarial staffs of the Institute for Petroleum and Organic Geochemistry at KF A and IES for their assistance and support throughout the research programs described here and in the preparation of the book. The book is a testimony to their professionalism and technical excellence. Finally, I wish to extend my personal thanks to Mr. Klaus Hebben (Monaco) for his long-term support and encouragement.
