Abstract

One of the most important characteristics in the reservoir studies known as "determination of porosity and permeability". Porosity and permeability determination is done by different methods such as experiment on small samples in laboratory or insitu determination using well logs. The difference between these methods is due to SCALE EFFECT as changing in sample volume has different results. In this paper, the SCALE EFFECT on porosity and permeability variables from an oil reservoir using geostatistical approaches (basically VARIANCE OF MEAN) are considered. The results of autocorrelation function show that the lateral permeability increases with scale. This is different for vertical permeability, which decreases with increasing the sample scale.Study of the variorum function shows that the reservoir is anisotropic. The results obtained by VARIANCE OF MEAN approve this conclusion. So, VARIANCE OF MEAN can be used for studying the anisotropic behavior.
