    One of the simplest and most widely used methods of estimating the advance of a fluid displacement front in an immiscible displacement process is the Buckley-Leverett method. [1], [2]. The Buckley-Leverett theory [] estimates the rate at which an injected water bank moves through a porous medium. The approach uses fractional flow theory and.   HA was observed to quickly mobilize the residual oil by reducing the interfacial tensions of the water-oil system. Residual oil in unsaturated silicate sand with an approximate bulk density of g/[3] ranged from 30 to 42% (Table 2). Unstable immiscible fluid displacement in porous media affects geological carbon sequestration, enhanced oil recovery, and groundwater contamination by non-aqueous phase liquids. Characterization of immiscible displacement processes at the pore scale is important to better understand macroscopic processes at the continuum scale. A series of displacement Cited by:

Department of Energy.; Northwestern University (Evanston, Ill.)]. Fig. 8 depicts the variation of residual oil recovery with slug volume prepared using alkali (1 wt% NaOH). Initially oil recovery of % IOIP was obtained at PV and then additional oil up to % IOIP was recovered at PV.

Further increase in slug volume (up to 2 PV) resulted in less residual oil recovery till % by:   The oil upstream flowed along these oil threads to meet the residual oil downstream so that an oil bank was built. In the process of residual oil flowing along the oil threads, because of the cohesive force of the oil/water interfaces, it was also possible to form new oil droplets, which flowed downstream and coalesced with other oils.

– Changes mobility ratio of water-oil displacement more favorable in the case of (initially) undersaturated oil. Oil Swelling by Dissolved Gas – Residual oil contains less stock tank oil, thus increasing recovery even in the absence of any Sor. Enhanced oil recovery (abbreviated EOR), also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise.

EOR can extract 30% to 60% or more of a reservoir's oil, compared to 20% to 40% using primary and secondary recovery. According to the US Department of Energy, there are three primary techniques for EOR: thermal, gas injection. While oil/water interfacial tension decreased from 16mN/m to ×mN/m, the two-phase region became wider, and residual oil saturation decreased.

At the same time, water relative permeability at residual oil saturation increased, and ultimate oil recovery increased by %, % and % respectively. Effects of interfacial tension and emulsification on displacement efficiency in dilute surfactant flooding Article in RSC Advances 6(56) January with 99 Reads How we measure 'reads'.

Residual oil after water flooding can be classified into five types, that is, oil drop, oil column, oil film, oil cluster, and oil in a dead end, and oil film type has the largest quantity and the Author: Jian Hou.

Surfactant imbibition experiments were carried out with four surfactants and effects of interfacial tension and surface wettability on oil recovery were studied. A convenient imbibition process with quartz sands was used, and the experimental results suggest that anionic and non-ionic surfactants have higher oil recovery than cationic surfactant, and the sand Cited by: 4.

Modeling and simulation of microbial enhanced oil recovery including interfacial area David Landa-Marbán†, Florin A. Radu † and Jan M. Nordbotten† Abstract The focus of this paper is the derivation of a non-standard model for micro-bial enhanced oil recovery (MEOR) that includes the interfacial area (IFA) between the oil and water.

Conventional recovery methods (primary and secondary) typically extract approximately one-third of the original oil-in-place in a reservoir. Estimates (made in the late s) of worldwide oil in-place range up to trillion barrels; using that figure, it is estimated that the oil remaining as a residual oil saturation after conventional recovery would be approximately trillion barrels.

the oil recovery factor. When oil is displaced by water, the oil/water mobility ratio is so high that the injected water fingers through the reservoirs. By injecting polymer solution into reservoirs, the oil/water mobility ratio can be much reduced, and the displacement front advances evenly to sweep a larger Size: KB.

Russian’s oil recovery factors have been on the decline in the last 30 years because of the depletion of giant fields.

Describes approaches to improving the understanding of the fundamentals of displacement, with the goal of simplifying systems sufficiently to enable measurements and. The results indicate that the interfacial tension between polymer system with low interfacial tension and oil first reduced, then increased with the increasing of polymer mass concentration, when the polymer mass concentration changes form gram/Litre to gram/Litre, the interfacial tension is milli-Newton/meter order of magnitude Cited by: 1.

Chemical enhanced oil recovery (EOR) has been adjudged as an efficient oil recovery technique to recover bypassed oil and residual oil trapped in the reservoir. This EOR method relies on the injection of chemicals to boost oil recovery. Recently, due to the limitations of the application of chemical EOR methods to reservoirs having elevated temperatures and high salinity and Author: Afeez Gbadamosi, Radzuan Junin, Muhammad Manan, Augustine Agi, Jeffrey Oseh.

Water flooding is an economic method commonly used in secondary recovery, but a large quantity of crude oil is still trapped in reservoirs after water flooding. A deep understanding of the distribution of residual oil is essential for the subsequent development of water flooding.

on the oil/water interface to improve the effects of water flooding. Published results [1] show that stimulating bacterial growth in core samples can give significant increase in oil recovery.

Reduction in interfacial tension (IFT) by bacterial action is one of the proposed mechanisms for this increased oil recovery. Enhanced oil recovery - Lecture 1 1. Prepared By Yasir Albeatiy Enhanced oil recovery Introduction Enhanced oil recovery (abbreviated EOR) is the implementation of various techniques for increasing the amount of crude oil that can be extracted from an oil field.

The saturate, aromatics, resin and asphaltene components of paraffin-base (PB) and naphthenic-base (HB) crude oil are separated by chromatographic column.

The acidic components of crude oil are extracted by compounded polar solvents and identified by methyl esterification of diazomethane. The acidic components before and after asphaltene removal .Interfacial tension is the Gibbs free energy per unit area of interface at fixed temperature and pressure.

Interfacial tension occurs because a molecule near an interface has different molecular interactions than an equivalent molecule within the bulk fluid.oil during a past displacement event.

It follows that pores where residual oil occurs do not contain water to any significant extent. A scanning electron micrograph of residual oil ganglia appears in Figure 1.
