Preface

This book is intended for the use of geologist, geophysists, petrophysists, and engineers interested in building geologic models that can be converted into realistic reservoir flow models of carbonate reservoirs. The first edition of this book was focused on methods and approaches for constructing improved carbonate reservoir models. In this second edition these methodsare enlarged based on research results since the first edition was published. Each chapter contains new information, particularly in the area of wireline logs and geostatistics. Importantly, several new field studies are included that illustrate the application of these methods in building reservoir models. As in the first edition, the integration of geological and engineering data is at the centerof the approach described in this edition. The fundamental link between geologic models and engineering fluid-flow models is the relationship between petrophysical properties and rock fabrics. Pore geometries control the flow properties and geologic history, as observed in rock fabrics, controls the pore geometries. Therefore, it is the study of rock fabrics that integrates geological andengineering data. Not surprisingly, the approach is referred to as the “rock-fabric method.” This method is an outgrowth of the published works of G.E. Archie (Gus), and the reader is encouraged to read the few reference to his work presented at the end of this Preface. The author is well acquainted with his work because Gus hired the author into Shell Oil in 1954 and work for him at Shell Development’sresearch laboratory in Houston for a number of years. Gus pioneered the idea of relating petrophysical properties to rock fabrics, an idea that was further developed by Ray Murray and myself in carbonates, and Robert Sneider in clastics. In this book I present a current picture of how this method can be applied in limestone, dolostone, and touching-vug reservoirs. The chapters have beenreorganized to accommodate the research advances in the past nine years. Reservoir characterization is first and foremost concerned with developing 3D images of petrophysical properties suitable for input into fluid-flow computer simulators. Therefore, as in the first edition, the first chapter is a review of petrophysical data and how the data are obtained. The second chapter discusses relationships...
