Evaluation of Physico-chemical Properties of Dar Oil Fields and Their Impact on Its Blend Quality

Abstract

Dar oil fields composed of palouge, Adar, Gummry and Moleeta. Adar and Gummry Crude oils are lighter than moleeta and palouge due to their low specific gravity and viscosity, however, the evaluation of physicochemical properties of Dar oilfields and their impact on Dar blend quality is important. That Gummry and Moleeta crude oils have a great impact on Dar blend especially in the specific gravity and Viscosity. The statistical analysis data collected from Dar oil fields showed the variation in physical properties over 12 years.Dar blend quality variation against field expansion as the new wells increase production; this variation reflects abundant groups of hydrocarbons. However, the Gummry and Adar oil are good Quality and have significant influence on Dar blend.Some suggestions were proposed for improvement of Dar blend Quality by increasing the proportions of Adar and Gummry crude oil.
