Surface chemistry has a great effect in enhancing oil recovery. For oil-wet sandstone reservoirs, low salinity waterflooding (LSWF) is effective as it can alter rock wettability and reduce the oil/water interfacial tension. LSWF application is related to rock’s clay content and type. Clay hydrocarbon bonding can be formed through many mechanisms such as van deer waals forces and ionic bridge. LSWF effect is to weaken these bonds through two main mechanisms, Double Layer Expansion (DLE) and Multicomponent Ionic Exchange (MIE). Two fields (S and D), in Egypt’s Western Desert, have depleted strongly oil-wet reservoirs with similar rock and fluid properties. Field (S) is flooded by low salinity water (LSW), while Field (D) is flooded by high salinity water (HSW). Fortunately, the water source for Field (S) flooding is a LSW zone, which has a salinity +/- 5000 ppm as total dissolved solids (TDS). The formation water salinity was +/- 25,000 ppm as TDS. Field (S) lab experiments showed good compatibility between injected LSW, formation water and rock minerals. XRD and SEM indicate calcareous cementation with detrital clays content around 5%. Kaolinite is the common clay type, which has a low cation exchange capacity. For Field (S), the estimated ultimate recovery (EUR) is 46%, while EUR for Field (D) is 39%. One of the main causes of this increase in Field (S) is LSWF application.

The importance of Enhanced Oil Recovery (EOR) technologies cannot be overemphasized, especially in the context of the surge in energy demand driven by rapid economic growth in developing countries as people strive to improve their living standards. Getting higher oil recovery from existing fields will be a key part of meeting the world's growing demand for energy. In the past decade, injection of brines of low salinity content and selected ionic composition in sandstone reservoirs has been developed into an emerging EOR technology. The advantage of low salinity waterflooding is that it is operationally comparable to conventional waterflooding and does not require expensive chemicals or carbon dioxide and nitrogen. The complexity of the crude oil/brine/rock interactions is well recognized and the mechanisms behind the low salinity EOR process have been debated in the literature for the last decade. The objective of this work is to explore by experimental study the effect of low salinity waterflooding on different outcrop and reservoir cores. Investigation of increased oil recovery by injection of low salinity water such as coalbed methane production water has been extended to reservoir cores from the Tensleep, Minnelusa and Phosphoria formations in Wyoming and outcrop cores (Berea and Bentheim). The Tensleep and Minnelusa formations are eolian sandstones of comparable depositional environment that contain interstitial anhydrite, dolomite and occasional calcite cements. The Phosphoria dolomite has pin-point to coarse vuggy pores lined by sparry dolomite crystals and also features patches of anhydrite. All the cores taken from pay zones showed increased oil recovery ranging from 5 to 8% original oil in place through injection of low salinity water. Increase in sulfate ion content of the effluent brine confirmed the dissolution of anhydrite, for all three reservoir rock types. Proposed mechanisms of recovery by low salinity flooding of sandstones which are tied to the presence of clay cannot apply because none of these rocks have significant clay content. Further evidence of the role of anhydrite dissolution was provided by the recovery behavior of Tensleep cores taken from the water-saturated aquifer zone of an oil reservoir. Anhydrite cement was sparse and only visible in occluded regions of pore space but not in regions that were clearly permeable. For these cores, there was no additional oil recovery when the injected brine was switched to low salinity water. The release of dolomite crystals and other fine embedded minerals which is likely associated with dissolution of anhydrite, may be a factor in the observed response to low salinity waterflooding. The movement of cement components is a possible contributing factor in the wide variety of observed relationships between pressure drop and oil recovery. For example, significant variation of relative permeability to brine at constant saturation is often observed.

Low-salinity waterflooding (LSWF) is a potential new method for enhanced oil recovery (EOR) in sandstone and carbonate rock formations. LSWF approach has gained an attention in the oil and gas industry due to its potential advantages over the conventional waterflooding and other chemical EOR technologies. The efficiency of waterflooding process is effected via reservoir and fluid parameters such as formation rock type, porosity, permeability, reservoir fluid saturation and distribution and optimum time of water injection. Combined effect of these factors can define the ultimate recovery of hydrocarbon. The main objective of this chapter is to review the mechanism of LSWF technique in improving oil recovery and the mechanism under which it operates. Various laboratory studies and few field applications of LSWF in recent years have been presented mainly at the lab scale. Also it will explore numerical modeling developments of this EOR approach.

This book aims at presenting, describing, and summarizing the latest advances in polymer flooding regarding the chemical synthesis of the EOR agents and the numerical simulation of compositional models in porous media, including a description of the possible applications of nanotechnology acting as a booster of traditional chemical EOR processes. A large part of the world economy depends nowadays on non-renewable energy sources, most of them of fossil origin. Though the search for and the development of newer, greener, and more sustainable sources have been going on for the last decades, humanity is still fossil-fuel dependent. Primary and secondary oil recovery techniques merely produce up to a half of the Original Oil In Place. Enhanced Oil Recovery (EOR) processes are aimed at further increasing this value. Among these, chemical EOR techniques (including polymer flooding) present a great potential in low- and medium-viscosity oilfields. • Describes recent advances in chemical enhanced oil recovery. • Contains detailed description of polymer flooding and nanotechnology as promising boosting tools for EOR. • Includes both experimental and theoretical studies. About the Authors Patrizio Raffa is Assistant Professor at the University of Groningen.
