    The question, whether it is possible to create such indicators that would allow to assess a saturation degree of reservoir pore space directly from seismic response, is interesting for hydrocarbon prospecting in the NE part of the Carpathian Foredeep. The dependence of seismic image of gas reservoir upon plenty of petrophysical parameters causes that the analysis of their influences on seismic response were based on seismic multi-variant modelling. Seismic model approximating »Łukowa« gas reservoir was constructed with Hampson-Russell System (CGGVeritas) accordingly with a geometry of profile no T0152005 acquired by Geofizyka Toruń Ltd. and additionally supported by log data from Ł-2 well. This paper presents results of the tests of interpretative procedures based on pre-stack seismic data such as AVO Product, Fluid Factor, lambdap and microp, elastic impedance. The correctness of established criteria was confirmed by a juxtaposition of an inflow rate obtained from a drill-stem tester and the interpreted seismic profile.
