Abstract
The feasibility of low salinity waterflooding in carbonate reservoirs are first evaluated through coreflooding tests and relative permeability curves are obtained. Next, the performance of low salinity waterflooding in one of the middle-east carbonate reservoirs is investigated. Finally, the results are compared in terms of economic profits by implementing the concept of net present value. The two-phase relative permeabilities from unsteady state coreflooding data are usually computed using JBN method. In this method, capillary pressures are neglecting. But in this research, a modified method used to calculate oil-water relative permeabilities which included capillary pressures. The economic evaluation of any IOR development strategy is a crucial factor for the success of the development strategy. Having the technical ability to increase the oil recovery by an IOR method is not enough to implement it. The economic feasibility of that method has to be studied before implementation. Beside using capillary pressure data in modified JBN method to obtain the relative permeability curves and a new method for averaging the relative permeability curves in an experimental and numerical calculation, using reservoir management techniques which includes economic evaluation and technical determination implemented in this study.
