The analysis of geological, laboratory and geophysical research results of Upper Jurassic carbonate rocks allowed to estimate fissurity indicator and investigation of fissured-cavernous zones in these complex' area. Researches of carbonate rocks mezostructure should be performed in the complex way, because these results help to draw practical conclusions about evaluation on account of reservoir properties. It should be accepted that only authoritative method of identification fissured zones doesn't exist.
The paper presents the results of petrographic investigations (included macro- and microscopic observations, X-ray and differential thermoanalyses) of the Upper Jurassic carbonate rocks from about 20 boreholes from the region on the east from Tarnów. The research shows that dolomitized carbonate rocks arc products of the dolomitization of fragmented earlier and partially redeposited limestone fragments. The effect of more intensive dolomitization of limestones is formation in some of levels porous structures, which allows to acknowledge them as reservoir levels for hydrocarbons.
