Resumen del autor, extraido del trabajo. A consistent screening technique was developed to quickly evaluate the Improved Oil Recovery (IOR) potential of oil reservoirs. This evaluation consists of : checking reservoir’s geological /production data for consistency, selection of technically feasible IOR processes, performance projection for the selected IOR processes, and generating a complete IOR report, containing all the production and injection plots. A software (PRIzeTM) was built based on this screening technique. This computer program generates information on the feasibility of IOR processes based on the average reservoir parameter values, the driving mechanisms, and the current understanding of IOR processes; analytical models are used for most predictions. These analytical models have been selected by distilling a significant number of forecasting methods in the open literature. This paper discusses the PRIzeTM-based experience in evaluating the potential of waterflooding, chemically assisted waterflooding, miscible gas injection (CO2, hydrocarbon, and N2), and thermal recovery processes (steam drive, SAGD and in-situ combustion). Options for using horizontal wells in conventional oil recovery and IOR processes are also addressed. Although PRIzeTM is not a numerical simulator, it allows one to establish, to a first order approximation, the likely performance for determining economic viability of a given IOR process.
