Ionic liquids for chemical enhanced oil recovery
THE INFLUENCE OF IONIC LIQUID TYPE, CONCENTRATION, AND SLUG Recent studies show that Ionic Liquids (ILs) have the ability to improve oil recovery. enhanced oil recovery; cold heavy oil production; slug concentration; slug 7 Jan 2015 For the further development of the field a CO2-EOR continuous simulations) does not include any ionic liquid components in its currently numerous EOR methods, which divided in categories are thermal, chemical, gas. Substantial amount of crude oil remains in the reservoir after primary and secondary production. Chemical flooding is one of the enhanced oil recovery (EOR) methods; however, chemicals (i.e., Surfactant) used are sensitive to the harsh environment characterizing the local reservoirs. The current study aimed at investigating the utilization of ionic liquids (ILs), known as environment friendly Surfactant flooding is one of the chemical EOR methods that can be implemented to recover oil from the remaining oil in place. Ionic liquids (ILs), which are salts with a melting point beneath 100 °C, were considered as a prospective alternative to the surfactant because of their superiority in different points. Chemical-Enhanced Oil oil recovery for secondary brine and tertiary ionic solution flooding at low S wirr. Contact angle and relative perme-ability measurements demonstrate the role of wettability alteration behind the extra oil recovery which is very much affected by ionic liquid concentration that can be altered by dilution with formation and injected brines. A significant portion of crude oil remains in the reservoir after the application of conventional recovery. To meet the growing demand of energy, enhanced oil recovery (EOR) methods should be used efficiently to recover the extra amount of trapped crude oil after secondary water flooding. Surfactant flooding is one of the chemical EOR methods that can be implemented to recover oil from the 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

The schematic mechanism of enhanced oil recovery by ionic liquids is presented in Fig. 4, which shows the specific adsorption of ionic liquid molecules at the interface between oil and water within the porous medium of reservoir from the aqueous ionic liquid solution. As the interface gets saturated with ionic liquid molecules, the IFT achieves

In order to improve oil recovery, Enhanced Oil Recovery (EOR) techniques have been applied to several light and medium oil reservoirs. This research was directed towards the development of chemical flooding methods for such reservoirs. The main objective of this experimental work was to investigate the efficiency of introducing various types of Ionic Liquids (ILs), 1-Ethyl-3-methylimidazolium
