This book will help geoscientists to understand how geostatistics fits into their workflow, what tools and techniques they should use, and what added value may result. Geostatistics is now used not only in reservoir characterization but also in velocity analysis, time-to-depth conversion, seismic inversion, uncertainty quantification, and seismic data integration in earth models. The 279-page book, part of the 2003 'SEG/EAGE Distinguished Instructor Short Course' includes sections on covariance and the variogram, interpolation, heterogeneity modeling, uncertainty quantification, and geostatistical inversion.
