Some Niger Delta oils were studied for the presence of diamondoids in the oils. Oils were obtained from a well each from their respective oil fields. The objectives of the study include identification of diamondoids in the oils, use of parametric ratios to delineate biodegradation and maturity of the oils. The m/z 136 show the presence of Adamantane and the m/z135 showed the presence of 1-Methyladamantane, 2–Methyladamantane, 1–Ethyladamantane and 2-Ethyladamantanein the oils. The nC17/Pr and nC17+nC18/(Pr+Ph) showed good biodegradation trend for the oils. 1MA/nC11 and nC17+nC18/(Pr+Ph plot did not show a good biodegradation gradient though of similar trend. 1MA/ nC11 showed a restricted spread. The plot 1MA/nC11 and 1MA+2MA/A showed a better spread for 1MA+2MA/A. The1MA/1MA+2MA (Methyladamantane index) showed a better maturity gradient and is good for the Nigerian oils but the 1EA/1EA+2EA (Ethyladamantane index) showed restricted spread for a good maturity gradient and may be better for higher matured oils than the Niger delta Oils.
