Perspektywiczne obszary poszukiwań węglowodorów w kambrze polskiej części platformy wschodnioeuropejskiej

Abstract

Primary areas for hydrocarbon prospecting in the Cambrian of the Polish Part of the East European Platform.S u m m a r y. Perspectives of prospecting for hydrocarbons in the Platform Cambrian strata of NE Poland are evaluated. The evaluation includes previous studies on type and distribution of sedimentary facies, possibilities of generating, accumulating and retention of hydrocarbons, reservoir properties of rocks, and presence of local structures. The results of their analysis presented herein allowed to delineate the optimum zone of occurrence of hydrocarbons, and to indicate primary areas within that zone to be prospected first. According to these criteria, the perspective zone for hydrocarbon prospecting in the Cambrian strata occurs on theWestern slope of the East European Platform and in its regional depressions, where the Cambrian occurs at depth 1500–3000 metres. A detailed analysis of geological data permits to pinpoint the following especially promising areas within that zone (fig. 7), best suited for hydrocarbon accumulation and deserving special attention: the Siedlce palaeoelevation; the Olsztyn palaeoelevation; an area near the Polish state border near Braniewo, Górowo Iławeckie and Bartoszyce; peri-Baltic part of the Łeba Elevation.
