Application of high resolution aeromagnetic data for determination of depth to magnetic sources using source parameter imaging in Niger State, Nigeria

Source Parameter Imaging (SPI) is a pivotal geophysical technique, particularly in aeromagnetism, for delineating subsurface geological structures through the analysis of magnetic anomalies. This study applies SPI to high-resolution aeromagnetic data over Baro and its surrounding areas in Niger State, Nigeria, to estimate the depth to magnetic sources. The research emphasizes the characterization of magnetic sources in terms of depth, geometry, dip, and susceptibility contrast. Data processing techniques, including regional field removal, residual anomaly mapping, and reduction to the magnetic equator, were employed to enhance data accuracy and interpretability. The findings reveal significant variations in sedimentary thickness, suggesting potential hydrocarbon reservoirs, particularly in the northern region, characterized by deeper basins. This study underscores the necessity of further exploration, integrating advanced seismic studies and drilling, to assess the hydrocarbon potential accurately. The SPI-derived insights provide a valuable framework for strategic hydrocarbon exploration in Nigeria's interior basins, contributing to the nation's energy security and economic growth.
