This book presents geostatistical tools for building numerical geological models of petroleum reservoirs. The use of geostatistical tools for modeling reservoir heterogeneities and assessing uncertainty in reservoir forecasting has increased significantly since the 1990s. There are many technical papers that track this growth in theory and applications; however, few collected works exist to bring together the practice of petroleum geostatistics into a coherent framework.
Building a suitable reservoir model calls upon the skills of many people. Geologists provide critical input on the sedimentology and stratigraphy of the subsurface. Geophysicists provide valuable information on the geometry of the reservoir and the internal distribution of reservoir properties in the inter-well region. Engineers, with their knowledge of flow processes and production data, provide critical information on connectivity and major heterogeneities. I do not address any single discipline; the emphasis is on the interdisciplinary interaction necessary to build numerical geological models consistent with all available information sources.
This book is aimed at the practice of geostatistical reservoir modeling; it is not intended to be a theoretical reference textbook. I focus on tools, techniques, examples, tradecraft, and providing guidance on the practice of petroleum reservoir modeling. Geostatistical Reservoir Modeling would serve as a reference text for the practitioner and be appropriate for an advanced undergraduate or graduate class on reservoir characterization.
