Abstract: The correlation between permeability and petrographical parameters in
cored samples can be used by extrapolations to predict permeability in uncored
intervals. The core analysis described here is concerned with the study of fluidrock
interactions in rock samples from three sandstone reservoirs, in particular the
effect of petrographical parameters on flow behavior. A positive correlation between
liquid permeability and the volume fraction of silica is clearly demonstrated. Liquid
permeability was correlated using multivariate regressions to one to five petrographical
parameters, the results of which have useful application in the estimation of reservoir
permeability where samples are not available for experimental testing.
