What is surfactant in oil recovery
3 Feb 2015 Hirasaki, George J.; Miller, Clarence A. Degree. Doctor of Philosophy. Abstract. The application of surfactants in Enhanced Oil Recovery (EOR) is 6 Mar 2015 The Enhanced Oil Recovery (EOR) technology covers the injection of specific type of a fluid or fluids into the reservoir by several methods (e.g.: Surfactant Enhanced Oil Recovery flooding boosts oil production by lowering interfacial tension, increasing oil mobility thus allowing better displacement of the oil by injected water. 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.

A surfactant is a compound that lowers the surface tension of a liquid, increasing the contact between the liquid and another substance. There are a wide variety of these compounds that work with oil, water, and an assortment of other liquids. Chemical enhanced oil recovery (EOR) is surely a topic of interest, as conventional oil resources become more scarce and the necessity of exploiting heavy and unconventional oils increases. EOR methods based on polymer flooding, surfactant-polymer flooding and alkali-surfactant-polymer flooding are well established, but new challenges always emerge, which give impulse to the search for new solutions.
Chemical enhanced oil recovery (EOR) and particularly surfactant injection has recently received a great deal of attention. The suggested recovery mechanisms
Crude oil development and production in U.S. oil reservoirs can include up to three distinct phases: primary, secondary, and tertiary (or enhanced) recovery. During primary recovery, the natural pressure of the reservoir or gravity drive oil into the wellbore, combined with artificial lift techniques (such as pumps) One of the most common methods for enhanced oil recovery is the utilization of different types of surfactants (synthetic or natural) in order to decrease the oil-water interfacial tension. However, the surfactants being used today are usually synthetic chemicals Surfactant flooding, also known as detergent or micro emulsion flooding, uses low concentration of surfactants augmented water to lower the interfacial tension between oil and water and in some cases alter the wettability of the rock to create favorable conditions for efficient oil displacement. A new type of green low surface energy surfactant (LSES) that is stable in the harsh conditions of enhanced oil recovery (EOR) has been reported. This efficient surfactant examined by scientists at Swansea University is shown to improve the oil recovery by 72% in both
Furthermore, surfactant can also drive the reservoir wettability towards more water-wet and lifting off the attached oil film from the pore wall, thus decreasing residual oil saturation and enhancing oil recovery.
Surfactants in Oil & Gas and Paints & Coatings Oxiteno also serves other markets, such as oil & gas, by offering non-emulsifiers and flow-back aids (non-ionic surfactants) as well as corrosion inhibitors (cationic surfactants) used in drilling and fracking to increase oil recovery.
