Numerous studies have proved the connection between low-amplitude local anomalies of gravity and magnetic field with oil and gas deposits in both platform and geosynclinal areas. In theoretical and experimental studies, gravity and magnetic prospecting methods for forecasting oil and gas accumulations in various geological structures have been used. They show out that oil and gas deposits located in different oil and gas regions of the world are noted discoveries with geophysical methods, including gravitational and magnetic fields. As a result, new exploration signs have identified the appearance of local gravitational and magnetic minima of various intensities above the productive parts of the structures. It has been established that the first physical and geological prerequisites for using gravimetry and magnetometry to explore hydrocarbon deposits in Azerbaijan are decreases in the density and magnetic susceptibility of rocks in the area of the deposit. Gravity-magnetic studies carried out in the Kura depression show that over the known deposits (Muradkhanly, Jafarly, Tarsdallar, Gazanbulag, Babazanan, Bandovan, etc.), gravitational and magnetic minima of 0.2-0.8 mGal and 20 -30 nT. the Physical and geological properties of the Muradkhanli field have been modeled by studying some of the physical parameters in the Middle Kura depression of Azerbaijan (the changes in the magnetic susceptibility, temperature, and density of rocks in the subvertical zone above and below the reservoir). In this study, the results of gravimetric and magnetometric studies performed for oil and gas deposits on the areas of Arabkubaly, Naftalan, Northern Naftalan, Gedakboz of Azerbaijan are presented. Consequently, the outcomes of experimental and systematic work carried out in the areas of Middle Kura Depression and Lower Kura Depression show the effectiveness of gravity-magnetic methods.
