Due to high importance of the crude oil to the modern society as a source of energy and as raw material for a wide chemical and petro chemical industries.
In this study we made assessment of metals and heavy metals in some Yemeni crude, and fuel oils namely Mareb crude oil blend, Masila crude oil blend plus two samples from Sounah and Hijah oil fields in Masila basin.
Fifteen metals and heavy metals were determined in above samples, but the most indicated were ( Na, K, Mg, ) and ( V, Co, Ni ) using ICP technique and atomic absorption spectroscopy .
The order of concentration of metals in Yemeni crude oils were as shown in figures:
Na < K < Co < Mg < V < Ni < Ca< Fe < Cd < Al< Zn < Cr < Cu < Pb < Mn.
In Fuel oil: Na < Co < V < Mg < K < Ni < Ca < Fe < Al < Cd < Zn < Cr< Pb < Mn < Cu.
Comparing concentrations of metals in studied sample, in general were less than in crude oil and fuel oil in many countries. That mean Yemeni crude and fuel oil are the best in quality.
