... evaluated the application of low-salinity water flooding (LSWF), whose predominant oil recovery mechanisms strongly depend on reservoir properties and conditions, to a clastic reservoir in an offshore field in Vietnam through laboratory work and simulations. In the laboratory, three coreflood experiments...

... ABSTRACT The present study was aimed to develop a numerical simulator for predicting oil recovery process during low-salinity water flooding (LSWF). While various mechanisms have been proposed in the past decades, this study focused primarily on the cation exchange. The authors' previous core...

... to that of homogenous reservoir. The numerical simulation results showed that the reservoir heterogeneity reduced oil recovery factor by up to 7.4% comparing to homogenous reservoir, but the effects of reversibility of surfactant adsorption on oil recovery are different due to reservoir types. INTRODUCTION After...

... Abstract In this paper, an oil recovery process has been studied by injecting sodium metasilicate (Na 2 SiO 3 ·9H 2 O) solution to form blocking gel with CO 2 in larger permeability flow passes. The Na 2 SiO 3 ·9H 2 O solution is an alkali to reduce interfacial tension (IFT) reduction...

... recovery (EOR) technology which has been reported to improve oil recovery in several laboratory experiments and some field trials. LSWF is a very attractive EOR technique in terms of the lowness of operating costs and the smallness of the environmental influences around the reservoirs. Although several...

... Abstract Herein is discussed the physicochemical mechanisms occurring during wettability alteration in mixed wet rocks. Defined by the strength with which a petroleum fluid adheres to the surface of the reservoir rock formation, wettability is of a great interest for oil recovery. The present...

... test suggest that, to be miscible with reservoir oil, carbon dioxide requires less addition of enriched gas comparing to nitrogen or methane. But, the reservoir section model showed that a miscible nitrogen injection is better, with higher oil recovery factor than that of miscible carbon dioxide...

... Abstract Only few attempts have considered gas flooding as means of heavy oil recovery and subsequently have investigated into gas solubility towards heavy crudes. Even more, the credit has been only given to specific methods including thermal treatment and chemical injection. Considering...

... ABSTRACT In order to investigate the effects of viscous ratio (water/oil) and the connectivity of flow paths in fracture network on oil recovery from a single fracture, two kinds of water flooding simulations using lattice Boltzmann method have been conducted to single fracture models...
