Determination of DisplacementEfficiency Using (CPL1)Surfactant in Sudanese Oil Fields

Abstract

This research is trying to discuss the experimental investigation of determining the displacement efficiency of unrecoverable amount of oil using surfactant (CPL1) for a Sudanese oil field - Case study application in (CPL) center through five chapters. The research was working on how to proof the hypothesis that says using Chemical methods of Enhanced Oil Recovery (EOR) especially surfactant flooding produces additional oil than the natural energy of the reservoir (water flooding). The research carried out an experiment using a flooding station of the Central Petroleum Laboratory (CPL), this implementation was done to compare the displacement efficiency of the reservoir water flooding and the surfactant (CPL1). At the end of the experiment a list of the important results and recommendation were attached. The most important result of the research was that the surfactant (CPL1) displacement was proved successful in increasing the recovery factor of oil as well as it was cost and time efficient compared to the natural reservoir energy (water flooding), while The most important recommendation of the research was to apply this experiment on 3 – 4 plugs for more precision.
