Abstract:

Enhanced oil recovery using nitrogen injection is a commonly applied method for pressuremaintenance in conventional reservoirs. Numerical simulations can be practiced for the prediction ofa reservoir performance in the course of injection process; however, a detailed simulation might takeup enormous computer processing time. In such cases, a simple statistical model may be a goodapproach to the preliminary prediction of the process without any application of numericalsimulation. In the current work, seven rock/fluid reservoir properties are considered as screeningparameters and those parameters having the most considerable effect on the process are determinedusing the combination of experimental design techniques and reservoir simulations. Therefore, thestatistical significance of the main effects and interactions of screening parameters are analyzedutilizing statistical inference approaches. Finally, the influential parameters are employed to create asimple statistical model which allows the preliminary prediction of nitrogen injection in terms of arecovery factor without resorting to numerical simulations.
