Dear All 


Our refinery is located in Karachi, Pakistan. We process Arabian light crude because its atmospheric residue is highly suitable for lube base oil production due to its high viscosity and low pour point. We are the only lube base oil producer in Pakistan and our GRM is mainly depend on lube base oil production.


Due to current scenario, loss of supply from saudia arabia ARAMCO, i have been assigned to find crude alternate of Arab light that will suitable for lube base oil production. I searched but unable to find the crude alternate of Arab light although we found iranian light is same as arab light but due to sanction we cannot buy crude from there. In Pakistan we are the only one that produce lube oil so we don't have any references. Please suggest from your experiences and reference what other crude is process in rest of the world to produce lube base oil.


Arab light crude assay is attached.

Lube oil is made from the VGO part of the crude, so you should really compare the Arab Lt VGO fraction(s) with that of other crudes.


The AL crude assay that you use does not give properties of VGO fractions so it is rather useless for your purpose.

Your laboratory probably has relevant properties of those fractions.



I suggest you start looking at VGO properties from crudes from Kuwait, Iraq, Dubai, Oman and also Russian Export Blend.
