Studies and Implementation of Injector Well Conversion During Salak Field Operation

Abstract

Recent reservoir modeling work suggests that Salak reservoir performance would improve by moving injection from current infield locations to more distal areas. This injection realignment will also create additional value by allowing exploitation of infield injection areas with production potential. The Awi 9 conversion project is a typical example of this type of project that should allow the eventual conversion of all Awi 9 wells to producers. This project requires evaluation of reservoir performance, prediction of well production performance and design of surface production facilities such as additional separators, knock-out drums, piping and well pads.
This paper describes the work flow and practices applied to evaluate infield injection effects and reservoir responses to changes on injection strategy, assess production potential of injection wells and injection well conversion program. The paper also describes options for surface production facility design for Awi 9 conversion and criteria to select the best design option.
