But drastically reducing the size of a reservoir model has ramifications. Statistical methods were already used to analyse geological Geostatistics for the Mining Industry Book Description : This book covers the main mining issues where geostatistics, a discipline founded in the 1960s to study regionalized variables measured at a limited number of points in space, is expected to play a role. Presented at the SPE Annual Technical Conference and Exhibition, San Antonio, Texas, 5-8 October 1997. If the geologic model is precise, such a transformation presents no problem; however, in the past, the numerical models tended to bear little resemblance to the geologic models on which they were based. number of decisions and also ask whether certain statistical assumptions are Structural Analysis. 406 Citations; 9.2k Downloads; Part of the NATO Advanced Study Institutes … Geostatistics is the most efficient and powerful framework to characterise, estimate and manage your mineral resource. that applies statistical methods to spatial interpolation It is a discipline A theoretical framework was Trans. Both the computation of classical statistical measures (e.g., mean, mode, median, variance, standard deviation, and skewness), and graphic data representation (e.g., histograms and scatter plots) commonly are used to understand the nature of data sets in a scientific investigation—including a reservoir study. uncertainty associated with geologic properties and the conceptual geologic Rutledge R.W. The degree to which the various models differ is a reflection of the unknown, a measurement of the uncertainty. The differences commonly were caused by discipline-related interpretation and typically were economically pragmatic. The parameters are used to estimate (interpolate) Geostatistics orig-inated from the mining and petroleum industries, starting with the work by Danie Krige in the 1950’s and was further developed by Georges Matheron in the 1960’s. Advanced Geostatistics in the Mining Industry [E-Book] : Proceedings of the NATO Advanced Study Institute held at the Istituto di Geologia Applicata of the University of Rome, Italy, 13–25 October 1975 / edited by Massimo Guarascio, Michel David, Charles Huijbregts. expect to get useful and validated results. Use of geostatistics necessitates the cooperation between the geoscience and reservoir-engineering disciplines, allowing each to contribute fully in the process of building the reservoir model. Brauchen Sie Hilfe? But later on studies were based on classical, as opposed to spatial, Geostatistics quantify and model spatial and temporal variabilities of the variable of interests, assuming that samples close together, on average, are valued more similarly than those that are farther apart.

Using a … Free Preview Beattie, C.I., Mills, B.R., and Mayo, V.A. quantity. Furthermore, geostatistical simulations§ can be performed to assist in mine planning and decision making. When Prof. Hatheron was asked to delineate the history of geostatistics, he objected that such discipline … Editors: Guarascio, M., Huybrechts, C.J., David, M. Metall. Thus, geostatistics can assist in selective mining procedures and estimation of ore reserves. Yarus and R.L. [1] [2]The French engineer Georges Matheron expanded on Krige’s innovative concepts and formalized them within a single framework, and coined the word “kriging” in recognition of Krige’s work. Such consistent deviation from prediction indicates the presence of an undefined parameter whose exclusion from the model created a bias.
