Abstract

"Water production is a challenging problem to be controlled during hydrocarbon-reservoirs production life. Disproportionate Permeability Reduction (DPR) is often used as water shutoff treatment in production wells when other conventional solutions like mechanical isolations are difficult to perform. This study applied numerical simulation methods to diagnose the factors impacting DPR treatment success on macroscopic level and to see when, where and at which conditions DPR treatment can give best results.

This work indicated that the following points should be considered before DPR treatment is executed in any reservoir to get a successful treatment. Firstly, this research explored that DPR performance was excellent in both of water cut reduction and oil production rate improvement when the flow regime was viscous dominated (viscous- gravity number10), the effective period of DPR treatment was short-term remedy. Secondly, eight major factors which are G shape factor, Gel penetration depth, Frrw/Frro, oil viscosity, ratio of oil density to water density, reservoir thickness, permeability heterogeneity among layers, and production flowrate can pronounce or degrade DPR treatment success. Design of Experiments (DOE) shows that the most two important factors which affect DPR performance are oil viscosity and permeability heterogeneity (linear flow or radial flow).

Finally, this study would help identifying the operating parameters on which operators can produce after DPR treatment performed such as production rate. Also, this research would give predicting for DPR treatment performance depending on reservoir and well candidate conditions"--Abstract, page iv.
