Steam Flooding Pilot Test Design in FULA Central : Case Study

Abstract

With the decline in oil discoveries during the last decades it is believed that Enhanced Oil Recovery (EOR) technologies will play a key role to meet the energy demand in years to come. Enhanced oil Recovery methods had been used around the world for enhancing oil production and getting higher recovery factor from oil reserves, Sudan also seeks to take advantage of the enhanced oil recovery techniques. Steam injection is one of the most common and widely spread thermal recovery methods. It is mainly used in heavy oil reservoirs. In this project, the design of pilot test has been conducted. Sudanese field contain heavy oils which required applying Enhanced Oil Recovery (EOR) techniques to be capable to increase the cumulative oil production therefore, recovery factor increase. Also represented in this project a description for Fula Sub-basinand Bentiu formation. CMG Thermal simulator STARS had been used for simulation implementing. The pilot test results showed that the cumulative production raised to 22,230bbl. When applying steam flooding with increasing volumetric percentage of 31%, so we recommended implementing of steam flooding to Bentiu formation.
