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. 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. [Enhanced Oil Recovery, Drilling Fluids] A chemical that preferentially adsorbs at an interface, lowering the surface tension or interfacial tension between fluids or between a fluid and a solid. This term encompasses a multitude of materials that function as emulsifiers, dispersants, oil-wetters, water-wetters, foamers and defoamers. What is a Surfactant? 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.

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. Many companies manufacture a range of surfactants for various purposes, ranging from soaps to inks. Oil Chem Technologies is a technology provider of surfactants used for Chemical Enhanced Oil Recovery (EOR) including ASP and SP. ASP In the Alkaline Surfactant Polymer (ASP) process, a very low concentration of the surfactant is used to achieve ultra low interfacial tension between the trapped oil and the injection fluid/formation water. 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. 6.

Schramm, Karin Mannhardt, and Laurie Hodgins OILWELL,NEAR-WELL, AND SURFACE OPERATIONS 8. The Use of Surfactants in Lightweight Drilling Fluids 295 What is Enhanced Oil Recovery? In a conventional reservoir drilled with conventional methods, the expected initial extraction rate of available hydrocarbons maybe as much as 15% – leaving 85+% of hydrocarbons in the reservoir. Pump jacks and initial gas injection or thermal recovery can increase that capture to the 25-30% range.
In petroleum recovery and processing industry, surfactants are used at various stages, for example, injection in reservoir, oil well drilling, production, and plant process [ 22 ]. Surfactant consists of polar (hydrophilic) and non-polar (lipophilic or hydrocarbon loving) portion as shown in Figure 1 [ 1, 5 ].
