EOR SCREENING METHOD COMPARISON BETWEEN ANALYTICAL SCREENING AND QUALITATIVE SCREENING APPLICATION

Abstract

More than 60% of oil production in Indonesia come from the mature fields. Enhanced Oil Recovery (EOR) activities have been proven capable extending the economic life of the mature fields by significantly increase the oil production recovery. However, the success of EOR implementation in the field depends on the careful planning in the early stage by selecting the suitable EOR method that matches the reservoir characteristics. The purpose of this study is to provide a comparison of EOR screening using an application which combine static and dynamic conditions of the reservoir and able to perform the preliminary analysis needed for EOR planning in the early stage which also incorporates industry guidance as a reference of EOR method implementation in the field with similar reservoir characteristics. The study will be conducted in a field X clastic with single zone. This field will firstly be performed history matching and analytical screening before running the EOR screening application. In the EOR screening application, the field will be performed data validation and qualitative screening based on agent compatibility, macro ranking, pore scale ranking and industry guidance. Based on the application, the field X is more suitable to be injected by Polymer in the first rank and ASP in the second rank which is close to the analytical screening that results ASP in the first rank and Polymer in the second rank.
