Summary The Kolomyia paleovalley is located in the Southeastern part of the Bilche-Volytsia zone of the Precarpathian Depression. On the slopes of the Pre-Miocene surface of the paleoledges surrounding the paleovalley, overlay the terrigenous deposits of the upper Baden with good reservoir properties. Despite the considerable study of the region of the paleovalley by seismic survey methods, only a few insignificant oil and gas deposits were discovered here. Among the reasons there are complex seismogeological conditions and insufficient application of a complex of “light” geophysical methods. The article presents an analysis of gravity-magnetic materials for the Slobidko-Llisna-Kolomyia area, adjacent from the South-West to the central part of the Kolomyia paleovalley floor. As a result of the research, it was shown that the geometry of the slopes of the paleoledges, as well as the features of tectonics, are clearly reflected in the anomalies of the gravity and magnetic fields. This makes it possible to predict promising areas on the slopes of the Slobidko-Lisna and Kolomyia paleoledges for oil and gas prospecting. |
