Dear All,

I have read the threads relating to obtaining crude dead oil viscosity based on laboratory measurements for three different temperature values. Unfortunately, in my case it is not possible to perform laboratory testing and I need to depend on an empirical correlation developed by researchers.

I am looking for a best fit dead oil viscosity correlation among the dozens published, for waxy crudes in the API gravity range of 20-30 and temperature range of 30-70 degrees celsius.

Can someone help me in selecting the best fit correlation based on their experience for the aforementioned API gravity and temperature range.

Regards.

Look at "Petroleum Refinery Engineering" by W.Nelson - there are published correlations for crude oil viscosity.

Also have a look at http://www.fekete.com/SAN/TheoryAndEquations/Harmo... and see if there is any use of http://www.oilzonetools.com/oil_viscosity.html

Hello,
My experience is that you are better off getting specific information about the oil that you are using. Get some essay data and go from there. Correlations are to be used when you have no information whatsoever, and most times you can get a sample and then perform a test.

Best of luck
