Generation geometric model pore space network is possible thanks to (micro-CT). In calculations, Knudsen number should considered, as a condition, which classifies modelling approach allows use proper method (correct flow regimes). Using CFD gas (nitrogen) water through porous system was analysed....

Permeability is a property of rocks which refers to the ability fluids flow through each substance. It depends on several factors as pore shape and diameter. Also presence type clay has large influence permeability value. can be measured rock sample in laboratory by injecting fluid under known condition, but this provides only point information. Due dependence parameter many factors, deterministic estimation based measurement well logs problematic. Many empirical methods for determining are...

Summary A new algorithm is proposed for pore space segmentation. It has been shown that Fourier transform filtering combined with triangle method brightness thresholding gives satisfactory results even if X-ray tomography data are highly influenced by noise. Moreover, only two parameters have to be adjusted the user of this — namely FT bandpass filter.
