This book will help geoscientists 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 book, part of the SEG/EAGE 2003 Distinguished Instructor Short Course, includes sections on covariance and the variogram, interpolation, heterogeneity modeling, uncertainty quantification, and geostatistical inversion. (DISC on DVD, 752A, is also available.)
