Dobrudja Foredeep

The aim of the work was to find out the dynamics of naphthidogenesis in the Devonian deposits of the Dobrudja Foredeep. The studies were conducted using retrospective analysis based on the fluid-dynamic concept of catagenesis. As a result, a difference in the catagenesis regime in different parts of the depression was established for the first time. The generation and accumulation of hydrocarbons in the Tuzliv Depression and the Furmanivsk-Prymorsk region exhibit distinct characteristics.

Purpose. Demonstration of the lithofacial structure and reconstruction of the sedimentation conditions of the Eifelian deposits of the Biloliskyy block of the Dobrudja foredeep in the aspect of the formation of productive horizons and the localization of perspective objects. Methods. The complex of lithological, paleo-oceanographic, lithophysica, and well logging explorations.

Purpose. The main purpose of this work is studying of lithology features of sedimentary complex of Eifelian age within Biloliskyi block of Dobrudja Foredeep. Methods. Methods include lithofacial, lithmological and mineralogy-petrographical analyses. Results. Lithology structure of sections of Eifelian deposits has been determined. It is presented with variable interlayering of sulphate (anhydrites), carbonate (limestones, dolomites, and marlstones) and terrigenous (sandstones, siltstones, argillites) rocks.
