    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.

    The interpretation of seismic data incorporating an analysis of amplitude variations with offset was proved to be indispensable in terms of the hydrocarbon prospecting in many areas. A good indicator of hydrocarbons is a bright spot anomaly. It has long been an established method to check the value of this anomaly is the method of AVO (Amplitude Versus Offset). The aim of the work is to show the possibilities of interpretation of seismic data before submitting the direct gas exploration on the example of the research area Lancut - Kańczuga. First presented opportunities to improve the quality of seismic data, then calculate the volume reflectance Rs and Rp, and attribute Fluid Factor and implementation of crosscorrelation graphs Rp-Rs, and draw a line WET-TREND. The application of AVO method of the chosen seismic data from this area allowed us not only to unambiguously confirm the positive character of some observed seismic anomalies, but also to indicate potential directions towards which future studies concerning an AVO analysis should be faced.
