Exploring the possibility ofaccurately model in wettability alteration mechanism for LSW process via Eclipse simulator

In this paper, the proper modeling of the wettability modification mechanism in the process of water injection with low salinity was investigated using the eclyps simulator. Most reservoirs are in their late stages of production, and still a high percentage of oil is available in reservoirs; hence the need to find a way to increase oil production from these reservoirs is more and more felt. Hence, the methods of harvesting should be used. One of the ways of treating withdrawal can be low intake of water with salinity. In this project, the method of water injection with low salinity is investigated with the aim of increasing the recycling of oil. To achieve this goal, the Ellips simulator is used. The heavy oil fluid model is modeled for oil reservoir; then water injection is simulated with different salinity (low salinity). Salines are considered to be high salinity with a concentration of 45000 PPM and low salinity, with concentrations of 24000 PPM, 8000, respectively. Water injection with different salinity increases the recovery rate of oil. The results show that water injection with salinity of PPM is 8000, with an oil recovery rate of 38% to 50%.
