Abstract
The petroleum industry adopted the nuclear magnetic resonance (NMR) technology to beused for formation evaluation by the determination of the petrophysical formation properties. NMR can be used as an independent logging service that provides porosity and permeability indexes, as well as complete information on fluid type and saturation of the formation layers.In this work the possibilities of operative determination of the main volumetric-flowproperties ( porosity-permeality) of reservoir rocks by NMR relaxometry are shown. It wasobserved that NMR relaxometry provides information about the distribution of permeability-porosity properties of core samples both for the section as a whole and for each formation separately. The data obtained are compared with the results of lithological and stratigraphic analysis.
