    Zależności między parametrami petrofizycznymi klastycznych skał karbońskich w basenie lubelskim na przykładzie obszaru Stężycy
    (Wydawnictwa AGH, 2005) Jarzyna, Jadwiga; Bała, Maria
    Characteristics of porosity and permeability and Flow Zone Indicator, FZI, of the Carboniferous clastic rocks, especially of the Middle-Namurian Lower-Westfalian in the Stężyca region, Lublin Basin have been presented. There were discovered differences in FZI between the hydrocarbon deposit section and unproductive beds in the determined III complex and between III and II complexes. A statistical analysis was performed for petrophysical parameters, i.e. porosity, permeability, volumes of sand and shale in the wells: Stężyca 1, 2, 3K and 4 to reveal features typical for all Carboniferous data, III complex and hydrocarbon-bearing section of III complex. High correlation coefficients showed data are well correlated and porosity from cores, Poro, can be substituted by porosity from the comprehensive interpretation of logs, PHI. A division of elaborated data sets due to the FZI has been realized and statistical relations between permeability and porosity in homogeneous flow units have been established. Relations describing a mobility of media in pore space for FZI units appeared to be stronger than for the total data set. A method of a continuous K-logging in situ on the base of PHI has also been a result of conducted considerations.
