Abstract: This study deals with the integration of palynological, palynofacies and petrophysical analysis of shale sediments of the Agbada Formation to evaluate for their source rock potential. Palynological and palynofacies analysis were carried out using non-oxidizing preparation method on ditch cuttings from LEO-1 well with the aim of determining their thermal maturity and Kerogen types respectively while their total organic carbon (TOC) was estimated using the well corresponding petrophysical parameters. The thermal maturity was assessed using thermal alteration index (TAI). The miospore colour observed from light transmitting microscope ranges from yellow orange to dark brown. The TAI value results ranges from 2+ to 4-, with TAI value 3 dominant, which indicates that the studied sections of LEO-1 well is thermally matured to generate hydrocarbon.
