Performance analysis of water flooded reservoir: A case study of field “X”, Niger Delta


Usiosefe Ikponmwosa, Paul Ogbeide

This study presents the use of classical and conventional analysis technique such as material balance equation (MBE), voidage replacement ratio (VRR), capacitance resistance modelling (CRM) and decline curve analysis (DCA) coupled with performance diagnostics tools (such as GOR and WOR) for production data analysis with slight modification for the characterization, evaluation and performance prediction of water flooded reservoirs. The conventional Havlena - Odeh straight line plot was used as the basis for this analysis with little modification to accommodate the water injection term (Winj.). The single control volume representation of the reservoir was assumed and computations was carried out using Microsoft excel spreadsheet. The results from analysis shows that VRR and MBE successfully characterized the reservoir as a water flooded reservoir with negligible water influx, CRM indicated close to 70% sweep efficiency and an increase in oil recovery was still possible (up to 18.2% with cumulative production standing at approximately 3MMbbls of oil produced) as indicated from decline curve analysis (DCA). These results obtained showed that the methods and approach followed were coherent and can be extended to other reservoir types. This technique can be used as a quick and cheap reservoir performance analysis tool where and when time and cost is a constraint. Similarly, results from analysis can be used as a pre-requisite for detailed 3D reservoir simulation studies, as reservoir behavior and performance can be inferred from it.
