Trace elemental analysis using Instrumental Neutron Activation Analysis (INAA) of Crude Oils from seven oil fields in Niger Delta, Nigeria was studied, using Ghana Research Reactor (GHARR-1) operating at 15kW at a thermal flux of 5 x1011 ncm-2s-1. From the results nine trace elements were identified: Al, Br, Ca, Cl, K, Mg, Mn, Na, and V. This study and previous ones have shown that crude oils from Nigeria are lower in metal content compare to other crude oils elsewhere around the globe. The concentration ranges of the trace elements varied significantly (P<0.05) from field to field.
