oil and gas bearing

Cyclicity, lithofacial features and sedimentary environments of eifelian deposits of Dobrudja foredeep

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.

Selection of informative indicators for estimation of hydrocarbon potential of local objects in boryslav oil field

The indicators of geological structure and the local oil and gas bearing in the Boryslav oil field were studied and analyzed. Using the mathematical statistics (t-Student criterion), the extent of their influence on the nature of oil and gas structures was established. It was found out that the structural factor and the distance from the axis of the local structure to a deep fault determine the conclusion on the presence of oil and gas in the local objects of the oil field.
