    Zastosowanie hydrofobizacji w celu selektywnej izolacji wody w zawodnionych odwiertach eksploatacyjnych
    (2008) Jewulski, Jan; Zagrajczuk, Danuta
    In this paper, the theoretical background of hydrophobization process in porous media was shown. The results of laboratory research of porous medium effective permeability dependence on its surface hydrophobization were presented. Analysis was done for different kind of porous medium (quartz sand and calcareous sand) using Sulfapol E-20. Influence of surfactant concentration and temperature was analyzed.

    Zastosowanie związków powierzchniowo czynnych dla selektywnej izolacji wody w zawodnionych odwiertach eksploatacyjnych
    (2009) Jewulski, Jan; Zagrajczuk, Danuta
    In paper theoretical background about application of surfaceactive compounds for selective water insulation is presented. Laboratory investigation of porous rock effective permeability changes caused by surface hydrophobization results are shown. Analysis was done for different rock (quartz-sand and calcareous-sand). Sulfapol E-20 and Rokanol DB-7 were used for water effective permeability changes analysis, Sulfapol E-20 was used for oil effective permeability changes analysis. Measurements were done for different surfactants concentration and temperatures. Results analysis was done.
