چکیده
The present study investigates the effect of TiO2 nanoparticles on stability Enhanced Oil Recovery (EOR)-produced stable emulsion. chemical precipitation method is used to synthesize nanoparticles, and their properties were determined using various analytical characterization techniques such as X-ray Diffraction (XRD), High-Resolution Transmission Electron Microscopy (HRTEM), Field Emission Scanning (FESEM). evaluated by measuring oil/water (o/w) separation, rag layer formation, oil droplet size, zeta potential residual EOR produced laser scattering technique determine o/w separation. results showed that spherical-shaped anatase phase with an average particle size 122 nm. had a positive separation clarity separated water. aqueous phases’ 75% 45% without respectively. Laser analysis revealed enhanced light transmission in presence suggesting higher ASP-produced overall increase was recorded be 19% indicating decrease This can attributed improved coalescence’ action between adjacent droplets behavior interfacial film. An observable difference found before after addition where increased from 3 µm 35 µm. A similar trend also noticed nanoparticles. Zeta −13 mV −7 mV, which unstable emulsion range.

Microbial 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 کاملEnhanced Acoustic Separation of Oil-Water Emulsion in Resonant Cavities
This paper explores the use of acoustics for the recovery of oil in oil-water emulsions. A series of experimental studies were conducted using acoustic standing waves in resonant cavities as means of trapping oil droplets and enhancing oil separation. Several cavity configurations were explored and the frequency range used was between 1 MHz-2 MHz. Oil-water emulsions studied were made using min...
متن کاملA Pore Scale Evaluation of Produced Biosurfactants for Ex-situ Enhanced Oil Recovery
Microbial enhanced oil recovery (MEOR) is an economical method used to improve the oil recovery from reservoirs. In the MEOR techniques, by applying different microorganisms, a variety of products such as bioacid, biogas, biosurfactant, and biopolymer are generated, among which biosurfactant, one of the important metabolites, is produced by bacteria. It is worthy to note that bacteria are suita...
متن کاملOil-water de-emulsification using ultrasonic technology.
In this paper an oil-water de-emulsification process within large tanks using ultrasonic technology is presented. As the device would operate in hazardous areas, it should not consume an excessive amount of electrical power. Hence, the paper investigates the suitable oil-water concentrations (10-90% concentrations in step of 10%) which would lead to the fastest separation while consuming the mi...
