The paper contains the description of the latest discoveries made on the base of the DHI in the Rzeszów area. Total reserves in the Palikówka, Stobierna, Terliczka and Jasionka gas fields are estimated on 4.2 bln cm of high methane content gas.

The paper reviews the applied prospecting methods and potential methods of testing the seismic anomalies related to gas accumulation in the Miocene deposits of the Carpathian Foredeep. Since many detected anomalies is demonstrated by test drilling to have no commercial value, it is important to develop a set of effective methods allowing for verification of the hydrocarbon potential associated with particular anomalies.

During last 50 years of exploration more than 120 gas and oil fields were discovered in the Carpathian Foredeep. The bulk of produced hydrocarbons (97%, mainly gas), were contained in the Miocene deposits, with a further 3% in the Miocene basement. The Miocene contains only gas, while both oil and gas were found in the basement rocks. The Miocene gas reservoirs are typically multi-horizon and saturated by the gas of very high methane content, usually 95 - 99%. About 90 billion cubic meters of this kind of gas were already produced. The Przemyoel Gas Fields Group is the largest one in Poland with GIIP of the near 71 billion cubic meters and the cumulative field production, as of December 31, 2002, amounted to 55 billion cubic meters. Better prospecting methods, particularly the direct hydrocarbons indicators (DHI) methods, opened a new stage of the exploration of gas accumulations in the Miocene deposits. Only during last 8 years near 20 new gas fields were discovered with these methods. The history and the physical background of the DHI methods were presented.

The paper contains the description of the latest discoveries made on the basis of the DHI in the extreme NE part of the Carpathian Foredeep. Total reserves of Biszcza, Dzików, Wola Obszańska, Księżpol, Łukowa, and Luchów gas fields are estimated on 5.5 m3 of high methane content gas.
