Changes of Physico - Chemical Properties of Gummry Crude oil on Dar blend

Aban C.O. Deng | Abd Elsalam A.Daffaalla

Abstract: This study was conducted on Dar crude oil physical, chemical, Rheological properties and operational parameters for the purpose to give an idea about Dar fluid properties after the new oil field Gummry started the production with the oil properties different from the previous Crude Oil. Data were collected from Dar crude oil Daily reports, including Specific gravity, API, Water and sediment, Viscosity and total acid number. The result showed that The new Dar blend which include Gummry Oil field affected the physical and chemical properties of Dar blend especially in the API which increased up to 26.11from 24.37 (average), there is no change in the pour point. The change in the Rheological Properties is very sharp which shows Viscosity of the new blend decreased. This change affects the Water separation performance. Chemical properties of Dar crude change because TAN content in Dar blend was decrease to 2.90 from 3.43 mgKOH/g.
