Abstract
This paper provides analysis of the anomaly gravity and magnetic fields in Solotvyno depression and how they are comparable with potential gas-bearing structures. Gravity and magnetic surveys of the different scale cover the whole studying area, which made them the basics for further geophysical studies and drilling. In this research, gravity data was processed by the moving average method and by transformation into lower subspace. As a result, anomalies of different origin were defined, including regional effects from the neighbor structures (Vyhorlat-Gutin Ridge), salt tectonics – and linear trends of anomalies along the Solotvyno depression which were compared with the well-testing data. Provided examples display the intensive effect of salt and volcanic formations on the recorded values which overlaps effects from gas reservoirs and puts uncertainties in their definition.
