Multivariate geostatistical simulation of compositional data using Principal Component Analysis
… we present a simple methodology for multivariate geostatistical modeling of compositional data using Principal Component Analysis (PCA). According to the methodology, grades are, first, transformed to log-ratios. Then, these log-ratios are linearly transformed to Principal Components (PCs). PCA …

On the spatial modelling of mixed and constrained geospatial data
… on the original compositional data. Several geostatistical techniques have been developed recently for the spatial modelling of compositional data. However, few of these consider the joint statistical and/or spatial relationships of regionalized compositional data with the other dependent …

Fractal relationships and spatial distribution of ore body modelling
… effort. The principal aim of almost every geostatistical modelling process is to predict the spatial variation of one or more geological variables in order to estimate values of those variables at locations that have not been sampled. From the spatial analysis of these variables, in …

Uncertainty in Geothermal Numerical Models: a Contribution from Geostatistics and Bayesian Methods
… of geological uncertainty was addressed by geostatistical simulation. Multiple-point statistics (MPS) algorithms were introduced. The main feature of a MPS algorithm is that it relies on a training image and through the use of multiple training images spatial uncertainties in subsurface flow …

Continuous reservoir model updating by ensemble Kalman filter on Grid computing architectures
… were developed and applied to designed reservoir simulation studies and continuous reservoir model updating. The toolkit provides reservoir engineers with high performance computing capacity to complete their projects without requiring them to delve into Grid resource heterogeneity, security …

Synthetic High Resolution Block Model for Benchmarking Mining Technologies
Variability of the rock properties and the uncertainty associated with their estimation in the blocks mined and processed becloud the decision making in the mining value chain. In addition to grades of elements and minerals of interest, the presence of deleterious materials, as well as varying …
