| Abstract | It is recognized that Salak reservoir performance would be improved through moving injection from current, infield locations, to outfield locations. During the last two drilling campaigns, several injector wells have been drilled outside of the proven reservoir boundary to replace existing infield injectors. Drilling wells outside of the known reservoir has always been challenging. A number of newly drilled wells have low permeability which limits their injection capacity due to poor connectivity to the large fracture network. Hydraulic stimulation on one of those wells had been applied and successfully improved injectivity. This paper describes the best practices applied during planning, designing and operating the hydraulic stimulation as well as technique to interpret surveillance data collected during stimulation. |
