Abstract
Magnetic surveys are one of the most mobile and low-cost geophysical methods. However, direct searching of hydrocarbon deposits by the magnetic method was questioned for a long time because of the virtual absence of the magnetic properties of oil and gas. Last investigations indicate that physical–chemical reactions of hydrocarbon deposits with the host media often create precursors for detecting directly magnetic signals from the oil and gas deposits even in the cases of large depths. Extraction of low-signal magnetic anomalies generated by hydrocarbon deposits is demonstrated on examples of several deposits from the Middle Kur Depression (Azerbaijan) and Dnieper-Donets Depression (Ukraine). Application of the proposed magnetic data analysis will allow not only to optimize hydrocarbon deposit searching in complex geological environments but also to decrease the number of prospecting boreholes.
