Applications of Magnetic Methods in Hydrocarbon Exploration

Magnetic data is useful in both hydrocarbon exploration and mining exploration. In hydrocarbon exploration, aeromagnetic data is an effective method for locating strike-slip faulting in magnetic basement. Also, high resolution surveys enhance delineation of both subtle basement features and intrasedimentary sources. In fact, magnetic methods has evolved from its sole use for mapping basement structure to include a wide range of new applications for better defining targets through ٣D inversion. Further, there has been a global surge in geochemical studies to understand magnetic mineralogy, in particularthose associated with hydrocarbon seepage and migration that could result in weak magnetic signatures. Thus a combination of recentdevelopments in various fields has resulted in making the Magnetic Method for hydrocarbon exploration.
