Abstract:

The paper presents the results of 25 industrial double-cycle drill stem test DST of the Malm carbonate rocks of the Carpathian Foredeep. Designated prospective levels were tested by DST to assess their productivity. DST tests were performed mostly in open hole sections of boreholes and rarely in cased hole - after earlier borehole casing perforations. Probes used American Standard company Halliburton and Baker Inflatable type. During testing of Malm reservoir rocks in approximately 75% was used double-cycle drill stem test DST. Due to renewed interest of the Polish Oil and Gas Company in petroleum prospection of Malm sediments, it is appropriate to use in the petroleum exploration results obtained thus far from industrial research double cycle DST reservoir testing. This provides, among others to modification of drilling technology and to sampling of Malm sediments in the planned boreholes.
