In this article objective have been made to reviews different geostatistical methods available to estimate and simulate petrophysical properties (porosity and permeability) of the reservoir. Different geostatistical techniques that allow the combination of hard and soft data are taken into account and one refers the main reason to use the geostatistical simulation rather than estimation. Uncert...

Inverse problems in geophysics require the introduction of complex a priori information and are solved using computationally expensive Monte Carlo techniques where large portions of the model space are explored . The geostatistical method allows for fast integration of complex a priori information in the form of covariance functions and training images. We combine geostatistical methods and inv...

Availability of georeferenced yield data involving different crops over years, and their use in future crop management, are a subject growing debate. In 9 hectare field Northern Italy, seven years data, including wheat (3 years), maize for biomass (2 sunflower, sorghum, comprising remote (Landsat) normalized difference vegetation index (NDVI) during central stages, soil analysis (grid sampling)...

Data from the acoustic surveys of MV SA ‘‘Agulhas’’ and FRV ‘‘Walther Herwig’’, and the 1981 RRS ‘‘John Biscoe’’ South Georgia acoustic survey were analysed by geostatistical methods. Estimates of mean density (g m) of krill and their variances are compared with published results from statistical analyses based on random sampling theory. A further high-resolution geostatistical analysis of the ...

Conventional wisdom suggests that the public release of financial analyst output is informative to traders about firm value. However, empirical tests of this mechanism have encountered difficulties in isolating the release of analyst output from concurrent intervening events such as analysts’ private-client communications. Earnings conference calls provide a unique opportunity to overcome this ...

A variety of methods have been used to make evolutionary inferences based on the spatial distribution of biological data, including reconstructing population history and detection of the geographic pattern of natural selection. This article provides an examination of geostatistical analysis, a method used widely in geology but which has not often been applied in biological anthropology. Geostat...
