Abstract
The study area is called abu tumayam trough in the western sirt basin, northeastern libya. The abu tumayam trough's basement configuration and tectonic evolution have been interpreted using potential field (gravity and magnetic) and 2d seismic data to support exploration operations. Gravity and magnetic data have been analysed using high-pass filters, total horizontal gradients, cet grid analysis, theta derivatives, source parameter imaging (spi), euler deconvolution, gm-sys inversion modelling, and werner deconvolution. This study utilised 2d seismic lines and well data to generate accurate and reliable subsurface models. The bouguer gravity and residual bouguer gravity anomaly of the abu tumayam trough show a central region have low gravity anomaly values ranging from -52 to -7 mgal and -26 to 18 mgal, respectively, while the total magnetic intensity (tmi) and reduction to the pole had the highest anomaly value of 320 nt in various regions. The reduction to the pole map (rtp) had the highest anomaly value of 405 nt in the eastern region. According to gravity and magnetic data, the total horizontal gradient, cet grid analysis, theta derivative, and euler deconvolution all show faults trending nw-se, ne-sw, nnw-sse, ene-wsw, and n-s.
