The purpose of the investigation is to detect new anticlinal structures that may contain hydrocarbons.
Design/methodology/approach. Surfaces of the layers’ azimuthal inclinations were built by using structural maps of reflective seismic horizons. On the examples of already discovered hydrocarbon fields, an idealized drawing of surface corresponding to anticlinal structures was marked. During the investigation we used maps of reflecting horizons in the lower Permian structural floor. The area of research is located in Orchik depression in the south-east of the Dnieper-Donets Basin.
Findings. Methodology was tested on the known fields. It permits to forecast the developing of anticlinal folds and their shape changes in the limits of the structural floor. By applying the described technique, we made a forecast of some new anticline bodies which could me be reservoirs for hydrocarbons.
Practical value/implications. This methodology is available for any kind of software related to geo-information. Besides, it can significantly reduce the cost of new hydrocarbon deposits search due to existing materials on seismic geophysical research.

Keywords: azimuthal picture, anticlinal structure, hydrocarbon trap.
