An Experimental Study of Surfactant Alternating CO2 Injection for Enhanced Oil Recovery of Carbonated Reservoir
Core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating CO2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. The core samples were provided from a low permeability mixed wet oil reservoir at 156 °F and 1900 psia. In addition, very few studies of surfactant adsorption on car...
متن کاملFluorosurfactants in Enhanced Oil Recovery
Fluorosurfactants are effective in a variety of Enhanced Oil Recovery (EOR) techniques including (i) improving subterranean wetting, (ii) increasing foam stability, and (iii) modifying the surface properties of the reservoir formation. While fluorosurfactants have been used in gas and oil exploration for four decades, the increased demand for petroleum and the greater understanding of the benef...
متن کاملMicrobial Enhanced Oil Recovery Using Biosurfactant Produced by Alcaligenes faecalis
A bacterial strain (designated as Alcaligenes sp. MS-103) isolated from oil sample of the Aghajari oilfield in the south of Iran, was able to produce an effective extracellular lipopolysaccharide biosurfactant (1.2±0.05 g/l) on molasses as a sole carbon source. The highest surface tension reduction to level 20 mN/m was achieved by biosurfactant produced by cells grown on molasses under optimum ...
متن کاملApplication of Nanoparticles for Chemical Enhanced Oil Recovery
In this paper, the potentials of using particles, especially nanoparticles, in enhanced oil recovery is investigated. The effect of different nanoparticles on wettability alteration, which is an important method to increase oil recovery from oil-wet reservoirs, is reviewed. The effect of different kinds of particles, namely solid inorganic particles, hydrophilic or hydrophobic nanoparticles, an...
متن کاملCharacterization of vesicle for Enhanced Oil Recovery
A systematic study has been performed employing the use of a cationic surfactant didodecyldimethylammonium bromide (DDAB), an anionic surfactant sodium lignosulfonate (SLS) and water for Enhanced Oil Recovery (EOR) from the underground porous media of the depleting oil field of Naharkotiya, Duliajan, in the Upper Assam basin, India. The strong electrostatic interaction between the oppositely ch...
