Evaluation of Multifunction Chemical Agent as Viscosity Reducer in Pipeline Case Study: (Wells:EF-14, FNE-16 andPAL-1)

Abstract

Viscosity has a major effect on fluid behavior. It determines how oil is extracted from a reservoir, how it is transported, how it is efficiently processed, and how it behaves as a product. There are various methods known to allow heavy oil pipeline transportation. These methods are; heating, dilution, aqueous emulsification and core annular flow. Multifunctional Heavy Oil Chemical Agent /viscosity reducer (MFHOCA)is one of the additives was used to enhance heavy crude oil transportation through pipeline in some Sudan oil field. In this study, three samples from different heavy crude oils from Sudan oil field were evaluated with different Multifunctional concentrations in different conditions; temperature, water cut, and shear rate. The results shown the optimum Multifunctional Heavy Oil Chemical Agent concentration is 0.5% after evaluating sample (1) with zero WC. Sample (2) and sample (3) were evaluated with MF 0.5% and all the result shown viscosity has significant reduction at low temperature (up to 30 Co), low shear rate (1-10 S-1) while water cut increasing.
