Source rock characterization of wells “F” and “O” within northern delta depobelt (Niger Delta Basin) – F.A. Lucas and O.I. Imasuen
Subsurface samples from two wells within the Northern Delta Depobelt (Niger Delta Basin) have been extensively studied in this research. The study was aimed at characterizing the organic matter content, assessing the quantity as well as determining the maturity status and therefore the hydrocarbon potential of the basin. Analytical results indicate total organic carbon (TOC), Maximum Temperature (Tmax), Hydrogen Index (HI), Oxygen Index (OI) values of 348 – 486 and 4-12 respectively as well as source rock type ranges of from >2.0 (wt%) 430-470 and type 1. The implication of this is a good – excellent source capacity and oil zone type 1. A cross plot of HI against OI, and HI against Tmax¬ indicate a type 1 kerogene which is oil prone. It is then deduced that sediments were deposited in an anoxic environment of low oxygen, containing good – excellent organic matter. Therefore, the source rock has the potential to generate oil rather than gas.
