Geologiceskie kriterii perspektiv neftegazonosnosti devonskih otlozenij v predelah Volyno-Podsol’skoj neftegazonosnoj oblasti

The basic geological criteria (structural-tectonic, lithofacies, geochemical and hydrogeological) enable the estimation of the prospects for the oil- and gas-bearing of territory and to determine priority directions for performing geological survey work. The complex analysis of the criteria of Devon oil and gas content in the limits of Volyno-Podillia oil- and gas-bearing region showed, that the structural-tectonic factor is the most important for total Devonian complex, and for the carbonate deposits of the Upper and carbonate-terrigenous deposits of Middle Devon — lithologic factor as well. It is determined, that the highly promising zone in the Lower Devonian deposits is within the limits of the center section of the Volyno-Podillia (northern and southern sections), for the Middle Devonian deposits — in the limits of central and northern parts on the basis of the geological criteria complex. The Upper Devonian deposits are highly promising in the limits of the central and northern parts of the region, and also in the limits of Volyno-Podillia monocline.
