Peculiarities of anomalous magnetic field in Ukrainian Carpathians territory were considered. It was stated that on the base of magnetic anomalies characters in can be divided in 4 zones that generally matches with main tectonic elements of the region (in SW – NE direction): Transcarpathian trough, Folded Carpathians, Precarpathian trough, SE edge of East-European platform. It was concluded that the peculiarities of geological structure and tectonics of Carpathians are reflected in anomalous magnetic field of the region.

The results of the study of temporal variations of local magnetic field in the Carpathian foredeep are presented. Local dynamic anomalies from 2 to 7 nT per year coincide with deep regional faults and marginal parts of tectonic zones and subzones and hydrocarbons deposits.
The results of magnetic studies on Orhovychi oil and gas field in the Carpathian Foredeep are shown. Specific features of structure of the local magnetic field and the magnetic susceptibility of soil are analysed.
The results of magnetic studies over hydrocarbons fields in the Outer zone of Carpathian Foredeep were studied. It was stated that upon oil and gas deposits are observed static and dynamic local anomalies connected with supervising tectonic displacements. The conclusion about genetic correlation between local anomalies and oil-and-gas content in the investigated deposits was done.
Purpose. Identifying of anomalous magnetic field peculiarities upon oil-and-gas bearing structures in the Carpathian Feoredeep and its relationships with oil and gas deposits. Methodology. Measuring of geomagnetic field T total vector modulus during surface magnetic survey on a geomagnetic profiles network. Measuring of core magnetic susceptibility of searching-prospecting wells. Investigations were done for 9 hydrocarbon deposits and 6 perspective structures in the NW part of Bilche-Volytsa zone, Carpathian Foredeep. Results. The analysis of anomalous magnetic field is shown.
