Abstract	Niger delta is one of the giant petroliferous provinces of the world. Following Shell-BP’s 1956 commercial discovery of oil in Oloibiri, Bayelsa State, exploration and production efforts have been intensified in Niger delta and other sedimentary basins in Nigeria. Although much work have been done on the source rock of the Niger delta petroleum system, the controversy as to whether the oil in Agbada reservoirs is produced within the formation or migrated from the over pressured Akata shales still remain unresolved. Organic geochemical analysis of the shales in one ExxonMobil hydrocarbon exploratory well X was carried out in order to evaluate the source rock potentials, kerogen type and maturity status of the sediments. The source rock evaluation revealed that soluble organic matter (SOM) ranges from1940 ppm to 4220 ppm with an adequate mean value of 2758 ppm. TOC ranges from (1.38 to 12.06) wt %; HI ranges from (226 – 568) HC/gCorg; Tmax value ranges from (385 – 440)0C; VR0 ranges from 0.51 – 0.76 and PI values ranging from (0.06 - 0.32) with the mean transformation ratio (TR) of 0.28 wt%. These show that organic matter quantity is fair to excellent and in high concentration with excellent hydrocarbon generation potentials and made of type II and type III kerogen. Vitrinite reflectance and TMAX values also showed that the source rocks in well X are predominantly matured at intervals therefore; Agbada Formation sourced the hydrocarbon in the study area. The oil window recognized at 8100ft, where the source rock profile exhibited the highest values of (TOC) 12.06%, genetic potential (55.47), S2/S3 (10.54), (TMAX) 431( 0 C) and (VRO) 0.6%, therefore, conclude that Agbada Formation sourced the hydrocarbon in the study area.
