Mining Workshop at the 67th EAGE Conference in Madrid - June 13, 2005

Description

This workshop will include a discussion on the main concepts of mining geostatistics and the practical solutions provided by geostatistics at the different stages of a mining operation. Many of the concepts will be explained by means of illustrations from real deposits. Discussions will benefit from the participation of the workshop attendees who are expected to include a wide range of professional disciplines, including geologists, mining engineers and managers.

The important differences between deterministic and stochastic approaches for estimating resources using exploration and production data will be highlighted. A sound understanding of the current capabilities of geostatistics to provide accurate models by optimizing the use of the information about deposits will be supplemented by discussions on future advances in the discipline.

Workshop topics for discussion will include the following:

 How geostatistics together with geology provide the most reliable estimates
 The fundamentals of the geostatistical approach
 The variogram for analysing the spatial distribution of grades
 The use of the variogram for estimating the resources: kriging
 The extension to the multivariate case and the cokriging
 Estimation of grades after cut-off and support effect
 Uncertainty assessment: from the kriging variance to confidence intervals
 Geostatistical simulations
