      Oil and Gas Recovery for Indonesia (OGRINDO ITB) is a Research Consortium in the Department of Petroleum Engineering, FTTM, ITB, and has researchers from various multidisciplinary sciences. OGRINDO ITB participated in facilitating surfactant screening by creating desktop tools. This research aims to develop desktop tools that will be useful for mapping surfactant performance in various types of fluids so that surfactants that have good performance will be the selected candidates for application in Indonesian Oil Fields. I joined the surfactant team with several jobs including: • Tested 32 surfactants for EOR applications with a total phase behavior test of more than 1000 data and interfacial tension test of more than 300 data. • Prepared materials for reports, presentations, and progress reports on a monthly and yearly basis to members, experts, and industry professionals ensuring effective documentation and communication of research findings, project status, and achievements. • Collaborated with cross-functional teams, including geologists and engineers to coordinate research activities and leverage expertise from various disciplines Show less
