Characteristic of Dar Blend Crude Oil Relevant to Pipeline Transport and Storage

Abstract

The study was conducted in Malute Basin, Block 3and 7 located in the South of Sudan. Samples of crude oils originated from 8 Oil Gathering Manifolds (OGM) of Palouge Field in, Malute Basin. Tests done for 0API (American Petroleum Institute Degree) was in the range of 13.70 up to 24.42، and tests for total acid number varying in the range TAN of1.11 up to8.23 mg KOH/g , and Density in the range of 0.9007 up to 0.9723.Viscosity was 124 in South West where in North Ogm was 8000 (cPoise). Pour Point was in the range 300C 420C. Then samples was collected from other three Fields (Adar Field, Gummry Field, and Moleeta Field).These Fields with Palouge Field were composed DAR Blend .The results of the study represents that crude oils from different locations in Palouge Field varied accordingly even the 8 OGMs has same source of Melute. Palouge crude oil according to API0 its quality is moderates that’s due to formations and depth of well from where oil was produced. Then the increased of viscosity and pour point leads to face troubles in transporting through pipeline within the seasons where temperatures decreased, and increasing in TAN leads corrosives of transport and storage equipments
