    Estymacja ciśnień porowych na podstawie wolumenu prędkości sejsmicznych
    (Wydawnictwa AGH, 2009) Górecki, Wojciech; Marecik, Tomasz
    The paper presents the methodology of computing the pore pressures with the use of the seismic velocity profile from migration analyses in the pre-stack version. The area of interest is localized in eastern part of Polish Carpathians between Rzeszów and Przemyśl in the vicinity of Rączyna, Jodłówka nad Drohobyczka wells. The migration velocity crossection were included for 17-2-91K seismic profile. The Eaton method was applied to calculate the pressure distribution in the geologic medium. According to Eaton's methodology the velocity compaction trend for normal condition were computed in clay intervals (clay volume more than 65%). The way of calculating the spatial model of seismic-wave propagation velocity based on 1D and 2D data was described. Final distribution of the pore pressures along the seismic section 17-4-91K located east of Rzeszów was presented.
