Thin liquid films in improved oil recovery from low-salinity brine
a r t i c l e i n f o Keywords: Low-salinity Waterflood LSW Brine Double-layer Sandstone Carbonate Film Low-salinity waterflooding is a relatively new method for improved oil recovery that has generated much interest. It is generally believed that low-salinity brine alters the wettability of oil reservoir rocks towards a wetting state that is optimal for recovery. The mechanism(s) by which the ...
متن کاملWettability Alteration of Oil- Wet and Water-Wet of Iranian Heavy Oil Reservoir by CuO Nanoparticles
The petroleum industry requires the best materials to reverse the rock wettability to water-wet state which give significantly improved oil recovery.Nanoparticles are suggested as enhanced oil recovery potential agents to decrease viscosity and alter the wettability of reservoir towards more water-wet. This study provides new insights into CuO nanoparticles effects on wett...
متن کاملFunctionalization of micromodels with kaolinite for investigation of low salinity oil-recovery processes.
Sandstone formations are ubiquitous in both aquifers and petroleum reservoirs, of which clay is a major constituent. The release of clay particles from pore surfaces as a result of reduced injection fluid salinity can greatly modify the recovery of hydrocarbons from subsurface formations by shifting the wettability properties of the rock. In this paper we demonstrate a microfluidic approach whe...
متن کاملManaging Injected Water Composition To Improve Oil Recovery: A Case Study of North Sea Chalk Reservoirs
In recent years, many core displacement experiments of oil by seawater performed on chalk rock samples have reported SO4 2−, Ca, and Mg as potential determining ions for improving oil recovery. Most of these studies were carried out with outcrop chalk core plugs. The objective of this study is to investigate the potential of the advanced waterflooding process by carrying out experiments with re...
متن کاملAn Experimental Investigation of Wettability Alteration in Carbonate Reservoir Using γ-Al2O3 Nanoparticles
Wettability alteration is one of the most important methods for oil recovery from sandstone and carbonate reservoirs. The effects of salinity, pH, temperature, and chemicals such as surfactants and fatty acids on the alteration of the wettability were described in previous studies. In recent years, attention has been directed to nanoparticles as a wettability alteration agent. The effect of som...
