Abstract
The viscosity at different temperature are measured for some Iraqi wells, A mathematical model was
proposed to describe the viscosity as a function of temperature depending on the experimental results ,
All the samples were collected from storage tanks of the following sites: South of Al Rumeela, North
of Al Rumeela, Al Halfaya and Bozorgan. The results give good agreement with the experimental
result that was measured for Iraqi wells, where the maximum average percentage of error was 7.4 % ,
the maximum AAD% was 4.4% and the maximum SD was 0.49013%.
