This paper describes step change improvement in managing remaining reserves recovery in DSF Field wide with enhanced capability to integrate dynamic well and reservoir data and conduct technical analysis to robustly identify and prioritize opportunities to pursue. Before this workflow and tool were established, Reservoir Engineers and Earth Scientists only had independent maps by area level. Remaining opportunity prioritization capability was only based on medium and high grading in area level that resulted in more than 700 patterns opportunities without clear comparison or prioritizations among areas. With this workflow and visualization establishment in PowerBI platform, all pertinent well and reservoir surveillance data were integrated and analyzed for insights thru PowerBI, thus all remaining opportunities in Duri Field wide were able to be identified, firmly prioritized, and monitored the performance. The prioritization process was more granular with capability of flexibility for live key parameter cut off adjustment to obtain the highest opportunities versus efforts to pursue. As a result of this new workflow process, project team got some recommendation to proceed the remaining opportunities. R sand have ~ 43 patterns and PK sand have ~250 patterns that need to be reviewed due to top remaining opportunity. With the quick review among project team and SME, project team have recommendation to increase injection ~ 4 MBSPD. The recommendation generated are not only in term of steam rate change, but also the recommendation is to add drainage point. The results are 21 injector need to be replaced, 28 injector Workover, 51 injector redeployment, 31 patterns need to do proactive job, 10 patterns to do pump optimization job, 65 patterns to checkerboard and 66 patterns already sufficient.
