Pore-size characterization in reservoirs is a critical step in assessing reservoir properties and predicting the productivity of oil reservoirs. This paper analyzes modern methods for deter-mining pore size distribution, including mercury porosimetry, nuclear magnetic resonance, X-ray tomography, gas adsorption, scanning electron microscopy, as well as semipermeable membrane and centrifugation methods. The physical principles, operating ranges, advantages, and limitations of each method are discussed. A comparative analysis resulted in a table com-paring the key advantages and disadvantages of each method.

Keywords: porosimetry, filtration and capacity properties, core analysis methods, oil and gas reservoirs, core, pore structure, pore size distribution, oil production, reservoir, formation.
