Studio 3 Geostatistics Introduction

Other pages in this series: 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9

Studio 3 offers a selection of geostatistical functions including inverse distance, nearest neighbor and a selection of kriging estimation methods and variogram model fitting. The computations include covariance and other parameters. The interactive variogram fitting process allows the user to display the experimental variograms, and to choose from a wide range of models and parameters; multiple nested structures and anisotropy are included. The models may be further refined statistically using cross validation techniques.

Grade Estimation:

• Variograms and/or cross variograms for up to 24 different variables in a single run
• automatic calculation of indicator values based on cut-offs 
• restrict by the specified key field eg rock type, or BHID to give downhole variograms 
• exclude pairs with the same keyfield value 
• optimized sample search for fast calculation 
• normal, relative and lognormal variograms 
• variograms for all directions calculated in a single run 
• optional rotated coordinate system ensures flexibility in definition of directions 
• options include angles of regularisation, cylindrical radius, lag tolerance, etc 
• output to a database file, and/or the print file together with summary statistics
