Abstract
Summary Gravity- Magnetic Potential Field Survey for Hydro-Carbon Exploration, in Azerbaycan Onland Summary Deep geological structures studied by gravity and magnetic exploration, based on Earth’s potential fields. Detailed mapping oil and gas deposits in gravity and magnetic fields were resolved. Decrease in density and magnetic susceptibility of rocks in oil fields, are proved by studying physical parameters in Middle Kura Depression, author quantitatively evaluated the change in magnetic susceptibility, temperature and density of rocks above and below the reservoir, on basis of which physical and geological model of the Muradkhanly Reservoir was compiled. New technique was developed to identify weak local gravity and magnetic anomaly associated with oil and gas deposits. A regional background field was constructed, so that it adjoins curves from side of the lowest value potential fields, which makes it possible to identify anomalies caused by structural constructions of deep geological environment. Depending on zones of gradient changes, characteristic local minima are distinguished against their background due to presence of HC deposits in section which is diagnostic sign of reservoir type anomalies. Successful results obtained by GM Exploration in Muradkhanly, Jafarly and Bozgobu Fields of the Middle Kura Depression.
