Prospects for the oil and gas content of the Maikop deposits of the Yevlakh-Agjabedi trough according to hydrogeological criteria

Abstract

Based on the analysis and generalization of geological and hydrogeological materials on the Maikop deposits, a schematic map of the oil and gas potential of these deposits in the Yevlakh-Agjabedi trough has been compiled, where highly promising, promising and unpromising zones have been identified. In the northwestern and southeastern directions, as well as in the central part of the trough and its northeastern side, the Maikop formations are hidden under a layer of younger sediments. Sediments of the Maikop series were uncovered by a large number of exploration and structural-search drilling wells within almost all areas of the Yevlakh-Agjabedi trough (Dalmamedly, Kazanbulag, Borsunly, Godakboz, Adzhidere, Sarialdag, Naftalan, Terter, Agdzhabedy, Beylagan, Sovetlyar, Amirarch, Zardob, Muradkhanly and others). The contact of the Maikop series with underlying formations in different areas of the Yevlakh-Agjabedi trough is expressed differently. Here, both a conformable transition from the Upper Eocene to the Maikop series and the transgressive occurrence of the Maikop on various Paleogene and Mesozoic horizons are noted, which is associated with the peculiarities of the geotectonic development of the trough.
