Abstract

This study for Moga oil field which Located in the eastern part of block 6, in Muglad basin located in south west of Sudan. According to the field under study Moga Sudanese oil field which characterizedwith low recovery factors and decline in primary production due to low oil gravity (<22 API) and viscosities above 100 CP, therefore the study to find the suitable method to increase the oil recovery efficiency. The study aimed to implement suitable development methods in Moga oil field to increase the recovery rates, Study the reservoir fluid properties by using CMG software. To achieve the objectives of this study, the below methodology had been followed: A deeply Understanding for Moga field properties, CMG software had been studied. Data collection for Moga oil field (reservoir characteristics, reservoir types, reservoir pressure, temperature, PVT properties of the crude oil, fluid and rock properties and reservoir parameters) The CMGmodel has been built for the Moga 26 area (17) wells, all the parameters had been entered to the software then model had been run for ThreeCases: Do Nothing Case (DNC), Water injection and Steam injection. The results obtained from three cases showed that water injection can increase the cumulative oil rate from 14.6 MMSTB to 26 MMSTB compared to DNC, Steam Injection scenario is better and can increase the recovery factor up to 65%
