Improvement of Oil and Gas Recovery by Optimal Well Placement
Authors S. S. Arsenyev-Obraztsov, A. I. Ermolaev, A. M. Kuvichko, G. Naevdal and A. ShafieiradIn this paper a study of optimal well placement algorithm based on Boolean programming (integer programming with Boolean unknowns only) and its influence on oil and gas recovery is considered. Because the structure of a reservoir is often complicated it i

Computer Model of Componentwise Gel Injection
By I. KuvshinovModeling results, which allow making a conclusion about potentialities of componentwise gel injection, for avoiding of an early gelation near the wellbore in hot wells, are presented in the article. Standard methods of gel injection imply using of homogen

Simulation of Hydrocarbon Gas Injection for Enhanced Oil Recovery in a Sector Model of Eastern Paydar Reservoir
Authors L. Monghad, B. A. Habibnia and S. S. GhorashiA numerical model has been developed for simulation of gas injection processes for enhanced oil recovery in a sector model of Eastern Paydar reservoir, located in a central oil field in Iran. The model incorporates two main elements. The first one is a fl

Enhanced Oil Recovery Techniques in Development of Bottom Water-drive Reservoirs
By A. PoushevOil reservoirs with bottom water drive have the advantage of a high oil recovery due to energy support from the aquifer. However, over time the encroachment of the water into the producing oil well caused by the pressure drawdown around the wellbore creat

Dissolution Behaviour of a Binary Mixture in a Capillary Tube
Authors M. S. P. Stevar and A. VorobevWe develop a pore-level physical model for the process of miscible displacement through porous media. Using the network model, the current task is reduced to the study of the dissolution dynamics of a binary mixture within a single capillary tube. Tubes o

Prospect of In – situ Combustion Applying as IOR Process on Russkoe Field
Authors M. A. Chudinov and G. M. NemirovichThe main oil deposits of Russkoye Field relate to the anisotropic reservoir with both sizeable gas cap and bottom water. The additional issue for petroleum engineering is heavy oil (0.91-0.94 g/cm3) with unique oil properties, high viscosity (140-360 mPa

Numerical Assessment of Cold and Hot-Water Floods for a Heavy-Oil Sandstone Reservoir in Middle East
Authors H. Alajmi and P. R. KingA combination of growing energy demand and oil price has been stimulating interests in both heavy oil (HO) resources and the methods of exploiting them. The vast volumes of these resources notwithstanding, their low reservoir-scale mobility precludes expl

Experimental Investigation of the Effect of Wettability and Drainage Rate on Tertiary Oil Recovery in Fractured Media
Authors P. Maroufi, M. Escrochi, S. Ayatollahi and A. JahanmiriVertical displacement of oil by gas is the most efficient known method for oil recovery from naturally fractured reservoirs. Unlike the homogeneous media, the ultimate oil recovery by gravity drainage in fractured media is very dependent on the production

Improved Oil Recovery in Carbonates by Modified Seawater – Optimal Ionic Composition and Salinity
Authors S. J. Fathi, T. Austad and S. StrandNot only the concentration of the active ions Ca2+, Mg2+, and SO42 is important for wettability alteration in a water-based EOR process, but also the amount of non-active salt, Na+ and Cl-, has an impact on the wettability alteration. Removing NaCl from the composition of the seawater improved the oil recovery about 10% of OOIP compared to seawater. In this work, we have modified the seawater depleted in NaCl by adjusting the concentration of the potential determining ions Ca2+ and SO42-. Outcrop chalk cores were used as the porous medium with an initial formation brine of 10%, saturated and aged in a crude oil with AN=2.0 mgKOH/g. The oil displacement tests were performed at 100 and 120oC by spontaneous imbibition of the optimized seawater. The concentration of SO42- in the imbibing brine had the largest effect on the oil recovery. When the concentration of SO42- in the seawater depleted in NaCl was increased four times, the ultimate oil recovery increased by about 20% of OOIP compared to the seawater depleted in NaCl. The amount of Ca2+ in the seawater depleted in NaCl had no significant effect on the oil recovery at 100 oC, but small improvements were observed at 120oC.
